config: dpi-aware: remove ‘auto’ value, and default to ‘no’
We now default to scaling fonts using the scaling factor, not monitor
DPI.

The ‘auto’ value for dpi-aware has been removed.

Documentation (man pages and README) have been updated to reflect the
new default.

.desktop: remove StartupWMClass from server, use distinct StartupWMClass for foot and footclient
For this to work, the default app-id of footclient has been changed
from ‘foot’ to ‘footclient’.

By using distinct StartupWMClasses, the compositor can connect a
running foot/footclient instance to the correct .desktop-file. This
ensures the correct icon is being used in e.g. docks, and that actions
like “open another window” works correctly.

Note that the user can override the app-id, either by setting app-id
in foot.ini, or with the -a,--app-id command line option.

utmp: rewrite utmp logging
This patch generalizes the utmp support, to not only support
libutempter, but also ulog (and in the future, even more interfaces).

* Rename config option main.utempter to main.utmp-helper
* Add meson option -Dutmp-backend=none|libutempter|ulog|auto
* Rename meson option -Ddefault-utempter-path to -Dutmp-default-helper-path
* utmp is no longer detected at compile time, but at runtime instead.

Meson will configure the following pre-processor macros, based on the
selected utmp backend:

* UTMP_ADD - argument to pass to utmp helper when adding a record (starting foot)
* UTMP_DEL - argument to pass to utmp helper when removing a record (exiting foot)
* UTMP_DEL_HAVE_ARGUMENT - if defined, UTMP_DEL expects an extra argument ($WAYLAND_DISPLAY)
* UTMP_DEFAULT_HELPER_PATH - path to the default utmp helper binary

The documentation has been updated to mention which arguments are
passed to the helper binary.

Add support for creating utmp records
This patch adds support for creating utmp records using the ‘utempter’
helper binary from the ‘libutempter’ package.

* New config option ‘main.utempter’
* New meson command line option, -Ddefault-utempter-path. Defaults to
  auto-detecting the path.

The default value of the new ‘main.utempter’ config option depends on
the meson command line option ‘-Ddefault-utempter-path’.

If ‘main.utempter’ is *not* set to ‘none’, foot will try to execute
the utempter helper binary to create utmp records when a new terminal
is instantiated. The record is removed when the terminal instance is
destroyed.

key-binding: new API, for handling sets of key bindings
Up until now, our Wayland seats have been tracking key bindings. This
makes sense, since the seat’s keymap determines how the key bindings
are resolved.

However, tying bindings to the seat/keymap alone isn’t enough, since
we also depend on the current configuration (i.e. user settings) when
resolving a key binding.

This means configurations that doesn’t match the wayland object’s
configuration, currently don’t resolve key bindings correctly. This
applies to footclients where the user has overridden key bindings on
the command line (e.g. --override key-bindings.foo=bar).

Thus, to correctly resolve key bindings, each set of key bindings must
be tied *both* to a seat/keymap, *and* a configuration.

This patch introduces a key-binding manager, with an API to
add/remove/lookup, and load/unload keymaps from sets of key bindings.

In the API, sets are tied to a seat and terminal instance, since this
makes the most sense (we need to instantiate, or incref a set whenever
a new terminal instance is created). Internally, the set is tied to a
seat and the terminal’s configuration.

Sets are *added* when a new seat is added, and when a new terminal
instance is created. Since there can only be one instance of each
seat, sets are always removed when a seat is removed.

Terminals on the other hand can re-use the same configuration (and
typically do). Thus, sets ref-count the configuration. In other words,
when instantiating a new terminal, we may not have to instantiate a
new set of key bindings, but can often be incref:ed instead.

Whenever the keymap changes on a seat, all key bindings sets
associated with that seat reloads (re-resolves) their key bindings.

fcft: adapt to API changes in fcft-3.x
Fcft no longer uses wchar_t, but plain uint32_t to represent
codepoints.

Since we do a fair amount of string operations in foot, it still makes
sense to use something that actually _is_ a string (or character),
rather than an array of uint32_t.

For this reason, we switch out all wchar_t usage in foot to
char32_t. We also verify, at compile-time, that char32_t used
UTF-32 (which is what fcft expects).

Unfortunately, there are no string functions for char32_t. To avoid
having to re-implement all wcs*() functions, we add a small wrapper
layer of c32*() functions.

These wrapper functions take char32_t arguments, but then simply call
the corresponding wcs*() function.

For this to work, wcs*() must _also_ be UTF-32 compatible. We can
check for the presence of the  __STDC_ISO_10646__ macro. If set,
wchar_t is at least 4 bytes and its internal representation is UTF-32.

FreeBSD does *not* define this macro, because its internal wchar_t
representation depends on the current locale. It _does_ use UTF-32
_if_ the current locale is UTF-8.

Since foot enforces UTF-8, we simply need to check if __FreeBSD__ is
defined.

Other fcft API changes:

* fcft_glyph_rasterize() -> fcft_codepoint_rasterize()
* font.space_advance has been removed
* ‘tags’ have been removed from fcft_grapheme_rasterize()
* ‘fcft_log_init()’ removed
* ‘fcft_init()’ and ‘fcft_fini()’ must be explicitly called

config: unify key- and mouse bindings
With this patch, key- and mouse-bindings structs (the non-layout
specific ones) are unified into a single struct.

The logic that parses, and manages, the key- and mouse binding lists
are almost identical. The *only* difference between a key- and a mouse
binding is that key bindings have an XKB symbol, and mouse bindings a
button and click-count.

The new, unified, struct uses a union around these, and all functions
that need to know which members to use/operate on now takes a ‘type’
parameter.

config: do key binding collision detection after loading the conf
This allows the user to write, to swap two key bindings:

  [key-bindings]
  show-urls-launch=Control+Shift+r
  search-start=Control+Shift+u

instead of:

  [key-bindings]
  search-start=none
  show-urls-launch=Control+Shift+r
  search-start=Control+Shift+u

This should simplify the configuration for people who replace a lot of
the default key bindings.

This also simplifies the parsing somewhat, since we no longer has to
parse a key-binding into a temporary list, ensure it doesn’t have any
collisions, and then copy it into the actual key binding list.

_While_ parsing a key-binding, we still need a temporary array (at
least for the time being), but that temporary array is no longer
visible outside the parsing function that allocates it.

config: add [colors].dim0-7
This allows you to configure custom colors to be used when colors are
being dimmed (`\E[2m`).

It is implemented by color matching (just like
bold-text-in-bright=palette-based); the color-to-be-dimmed is matched
against the current color palette.

If it matches one of the regular colors (colors 0-7), the
corresponding “dim” color will be used.

If it matches one of the bright colors (colors 8-15), the
corresponding “regular” color will be used (but *only* if the “dim”
color has been set).

Otherwise, the color is dimmed by reducing its luminance.

The default behavior, i.e. when dim0-7 hasn’t been configured, is to
dim by reducing luminance for *all* colors. I.e. we don’t do any color
matching at all. In particular, this means that dimming a bright color
will *not* result in the corresponding “regular” color.

csd: add support for a visible border
When we’re using CSDs, we’ve up until now rendered a 5px invisible
border. This border handles interactive resizing. I.e. hovering it
changes the mouse cursor, and mouse button events are used to start an
interactive resize.

This patch makes it possible to color part of (or the entire) border,
with a configurable color.

To facilitate this, two new options have been added:

* csd.border-width
* csd.border-color

border-width defaults to 0, resulting in the look we’re used to.

border-color defaults to the title bar color. If the title bar color
hasn’t been set, it defaults to the default foreground color (just
like the title bar color does).

This means that, setting border-width but not border-color, results in
a border that blends with the title bar.

729f7466ae notify: add the notify-focus-inhibit config option
foot doesn't show desktop notifications (via OSC777) if the current
terminal has keyboard focus.

This is probably a sane default, but there are use cases where showing
a notification regardless of the focus status may be desired. For
example, a completion notification of a long running task inside a
non-focused tmux window.

This PR adds the notify-focus-inhibit option which can be used to
disable inhibition of notifications when the window has focus.

The default value is `yes`, which retains the old behavior.

terminfo: install to $datadir/foot/terminfo by default, append to TERMINFO_DIRS
As of 2021-07-31, ncurses ships its own version of foot’s terminfo.

Since:

* It doesn’t have the non-standard Sync,Tc,setrgbf,setrgbb
  capabilities.
* It doesn’t set hs,fsl,dsl (statusbar).
* We want to be able to update our termminfo without waiting for an
  ncurses release.
* Foot should be installable and usable on Linux systems that doesn’t
  have the latest ncurses.

we still want to ship our own version. We can however not install it
to the default terminfo location (e.g. /usr/share/terminfo), since it
will collide with the ncurses provided files.

Our options are to either rename our terminfo to something else, or to
keep the name, but install our terminfo files somewhere else.

The first option would be the easy one. However, I think it makes
sense to use the same name. For example, a user that SSH’s into a
remote system that does *not* have our own version installed,
but *does* have the ncurses one, will gracefully fall back to that
one, which is better than manually having to set
e.g. TERM=xterm-256color.

Now, if we want to use the same name, we need to install it somewhere
else. But where? And how do we ensure our version is preferred over
the ncurses one?

I opted to $datadir/foot/terminfo (e.g. /usr/share/foot/terminfo) by
default. It makes it namespaced to foot (i.e. we’re not introducing a
new “standard” terminfo location), thus guaranteeing it wont collide
with ncurses.

To enable applications to find it, we export TERMINFO_DIRS. This is a
list of *additional* directories to search for terminfo files. If it’s
already defined, we *append* to it.

The nice thing with this is, if there’s no terminfo in that
location (e.g. when you SSH into a remote), the default terminfo
location is *also* searched. But only *after* having searched through
TERMINFO_DIRS.

In short: our version is preferred, but the ncurses one (or an older
version of our terminfo package!) will be used if ours cannot be
found.

To enable packagers full control over the new behavior, the existing
meson command line options have been modified, and a new option added:

-Dterminfo=disabled|enabled|auto: *build* and *install* the terminfo
files.

-Dcustom-terminfo-install-location=<path>: *where* the terminfo files
are expected to be found.

This *needs* to be set *even* if -Dterminfo=disabled. For example, if
the packaging script builds and packages the terminfo files separate
from the regular foot build. The path is *relative to $prefix*, and
defaults to $datadir/foot/terminfo.

This is the value that will be appended to TERMINFO_DIRS. Note that
you can set it to ‘no’, in which case foot will *not* set/modify
TERMINFO_DIRS. Only do this if you don’t intend to package foot’s
terminfo files at all (i.e. you plan on using the ncurses ones only).

-Ddefault-terminfo=foot. Allows overriding the default TERM
value. This should only be changed if the target platform doesn’t
support terminfo files.

91801ae55d render: Allow cells to bleed into their neighbor
This patch adds a `confined` flag to each cell to track if the last
rendered glyph bled into it's right neighbor.  To keep things simple,
bleeding into any other neighbor cell than the immediate right one is
not allowed.  This should cover most use cases.

Before rendering a row we now do a prepass and mark all cells unclean
that are affected by a bleeding neighbor.  If there are consecutive
bleeding cells, the whole group must be re-rendered even if only a
single cell has changed.

The patch also deprecates both old overflowing glyph options
*allow-overflowing-double-width-glyphs* and *pua-double-width* in favor
of a single new one named *overflowing-glyphs*.
