Now that all XML validation errors have been fixed, it is time to turn
the validation back on to make sure the errors stay out.

Creating an empty <variablelist> is illegal. This can already be seen in
the XSL anywhere it is generated. The used XSL programming pattern
requires the look-up conditions to be repeated between the <xsl:if> and
<xsl:apply-templates> tags. Usually this is not a problem, but the
conditions for memberdef is too much to copy around.
The conditions between the if and the apply-templates have already
diverged, causing validation errors (that are currently suppressed).
Rearrange the XSL so that the applicable memberdef are stored in a
variable, so that both the if and the apply-templates operate on the
exact same set of matches. This avoids emitting empty <variablelist>.
As a result, the members of structures wl_argument, wl_interface,
wl_message, and wl_listener newly appear in the documentation.

When generating documentation, xmllint complained:

These were referring to wl_signal_add() and wl_signal_emit() I think,
which are static inlines in a public header.
The XSLT ignored static functions, probably assuming that they cannot be
public API. Internal (static) functions are present in the Doxygen XML,
so they do need to be excluded. Now we include static functions if their
body is in a header. We de not scan private headers, so they must be
public API.
Comparing the final generated HTML documentation, these functions are
added to both Client and Server APIs:
wl_fixed_to_double
wl_fixed_from_double
wl_fixed_to_int
wl_fixed_from_int
These functions are added to the Server API:
wl_signal_init

Meson is a next generation build system, simpler than Autotools and also faster
and more portable. Most importantly, it will make integrating ASan easier in
CI.
The goal is to maintain feature parity of the Meson build with the
Autotools build, until such time when we can drop the latter.
Add a script which generates the desired Doxygen configuration for our various
output formats and executes it using that configuration. This is not something
Meson can or should do.

Make considers a variable called VPATH when trying to satisfy
dependencies, e.g. for a target 'foo', it will consider the target
extant if VPATH is '../../bar' and '../../bar/foo' exists.
Part of the doc build, the '$(alldirs)' target, exists to create the
target directories if they do not exist. For example, before generating
xml/wayland-architecture.png, it will ensure the 'xml' target is
considered up-to-date thanks to the target dependency.
Creating $(srcdir)/doc/doxygen/xml thus means that the 'xml' dependency
will be satisfied, so we'll never create the output directory, and the
doc build will fail.
Change the alldirs target list to be absolute paths, so VPATH will not
be consulted and defeat the entire point of what we're trying to do.
This fixes the Meson build, where we later create
doc/doxygen/xml/meson.build.

When wayland-scanner encounters a new_id field with no corresponding
interface name defined, instead of emitting a function whose signature
lines up with the usual case (a uint32_t ID), it adds the interface name
as a string and the version number so that the interface can be
identified from the protcol message.
Without docs, this was previously left for the interprid wire protocol
implementor (e.g. me an hour ago) to discover when Wayland clients send
them apparently bogus messages.
I would have preferred if a different primitive type were used here
(e.g. typed_new_id) to reflect the fact that the wire protocol is
different, but I felt it unwise to add a new primitive to wayland.xml in
$current_year.
The docbook-xsl package includes all the stylesheets required to build
the docs without internet access.
Test:
One way to emulate missing style sheets is to move /etc/xml/catalog file
to a different location. Doing so should cause configure to fail with
"checking for docbook stylesheets... no"

In order to support system compositor instances, it is necessary to
allow clients' wl_display_connect() to find the compositor's listening
socket somewhere outside of XDG_RUNTIME_DIR. For a full account, see
the discussion beginning here:
https://lists.freedesktop.org/archives/wayland-devel/2017-November/035664.html
This change adjusts the client-side connection logic so that, if
WAYLAND_DISPLAY is formatted as an absolute pathname, the socket
connection attempt is made to just $WAYLAND_DISPLAY rather than
usual user-private location $XDG_RUNTIME_DIR/$WAYLAND_DISPLAY.
This change is based on Davide Bettio's submission of the same concept
at:
https://lists.freedesktop.org/archives/wayland-devel/2015-August/023838.html.
v4 changes:
* Improved internal comments and some boundary-condition
error checks in test case.
* Refer to compositor as "Wayland server" rather than "Wayland
display" in wl_display_connect() doxygen comments.
* Remove redundant descriptions of parameter-interpretation
mechanics from wl_display_connect() manpage. Reworked things
to make it clear that 'name' and $WAYLAND_DISLAY are each
capable of encoding absolute server socket paths.
* Remove callout to reference implementation behavior in protocol
documented. In its place there is now a simple statement that
implementations can optionally support absolute socket paths.
v3 changes:
* Added test case.
* Clarified documentation to note that 'name' parameter to wl_display_connect()
can also be an absolute path.
v2 changes:
* Added backward incompatibility note to wl_display_connect() manpage.
* Rephased wl_display_connect() manpage changes to precisely match actual
changed behavior.
* Added mention of new absolute path behavior in wl_display_connect()
doxygen comments.
* Mentioned new absolute path interpretation of WAYLAND_DISPLAY in
protocol documentation.
