Only enable XDG activation when compiling against wayland-protocols
1.21. Older versions don’t have this protocol.
When available, define HAVE_XDG_ACTIVATION.
Make all usages of xdg_activation_v1 and xdg_activation_token_v1
conditional.
All of these include wayland.h (either directly, or indirectly), which
pulls in xkbcommon.h.

There are cyclic dependencies between the log, debug and xmalloc
libraries. While having them as separate static libraries work, as
long as consumers of them link against all of them, having them in a
single library feels slightly better.
This is the only time it’s needed.
In non-PGO builds, it is completely unnecessary, and we’re only
wasting CPU cycles building it.
In full PGO builds, with -Db_pgo=use, we get link warnings and/or
failures, depending on compiler, since the pgo binary hasn’t been
executed.
But appears to have been allowed in older versions of meson.
Fixes an issue where foot’s version was always reported as the last
stable release, even though it was a git build.
This requirement is due to the recently added maybe_repair_key_combo()
function, which is making use of xkb_keymap_key_get_mods_for_level().

ncurses on FreeBSD still uses termcap(5) while foot works fine with
xterm-256color sans status line and visible bell. Having more than
one ncurses version installed may break other applications.
Document -Dterminfo=false uses --term=xterm-256color by default
Base compiler on BSDs doesn't look where packages are installed to
avoid tainting build environment. When system fcft is installed to
the same prefix as wayland-client it passes CFLAGS that satisfy both
but when using subprojects/fcft there's a build error.

epoll/timerfd are Linux-only but BSDs have a shim via kqueue.
libwayland on FreeBSD uses epoll-shim by default, so the build may
fail at linking instead of compilation stage.

* ‘term’ struct contains an array of 160 fcft glyph pointers
* the glyph pointers are lazily allocated when we need to draw a box
drawings character
* Filtering out box drawings characters is easy - they are (except
unicode 13, which isn’t handled yet )all in a single range.
Dependency chains:
* pgolib -> terminal.c -> terminal.h -> wayland.h
* vtlib -> csi.c -> config.h -> wayland.h
wayland.h includes <primary-selection-unstable-v1.h>, which must be
generated by a custom_target() rule *before* any sources that require
it are built. Failure to fully specify these dependencies can otherwise
result in a race condition, where a dependent source file gets compiled
(and fails with a "header not found" error) before the header itself
has been generated.
