Embed the wayland.dtd protocol data into the scanner binary so we can validate
external protocol files without requiring makefile changes. Hat-tip to Pekka
Paalanen for the embedding trick.
The embedding trick doesn't work well if the to-be-embedded file is in a
different location than the source file, so copy/link it during configure and
then build it in from the local directory.
The current expat parser is not a validating parser, moving scanner.c to
another parser has the risk of breaking compatibility. This patch adds libxml2
as extra (optional) dependency, but that also requires parsing the input
twice.
If the protocol fails validation a warning is printed but no error is returned
otherwise.

The previous idiom for building a cross-compiled Wayland is to build once for
the build host (with --enable-scanner --disable-libraries) to get a
wayland-scanner binary that can then be used in a cross-compile (with
--disable-scanner). The problem with this is that the cross wayland is missing
a wayland-scanner binary, which means you then can't do any Wayland development
on the target.
Instead, always build wayland-scanner for the target and change
--enable/disable-scanner to --with/without-host-scanner. Normal builds use the
default of --without-host-scanner and run the wayland-scanner it just built, and
cross-compiled builds pass --with-host-scanner to use a previously built host
scanner but still get a wayland-scanner to install.
(a theoretically neater solution would be to build two scanners if required (one
to run and one to install), but automake makes this overly complicated)

When building just the scanner or docs it's not required.
This can reduce requirements for a host cross compiling wayland,
since only the scanner needs to be built natively.

This paritally reverts commit a4afd90f9f.
On older expat versions (ie the one on Ubuntu 12.04) there is no pkg-config
file, so fall back to a test for the header and library. In addition the
source for expat does not seem to be in a git repository but in cvs instead
and it seems preferrable to not require cvs to build wayland.
The restored test has been updated to use AC_SEARCH_LIBS. This version
uses empty square brackets for the unused branches, similar to many other
if statements in configure.ac.

This test includes one of wayland headers, which produced
error with C++ compiler. C compiler can't be used for this test,
because it issues only a warning[1] and only when wayland headers
are not installed in system headers path (/usr/include).

Publican isn't packaged for some distros, xmlto is a lot more common. Most of
what publican provides for us is the stylesheet anyway, so we can just use
xmlto and the publican stylesheet to get roughly the same look.
PDF and XML generation has been dropped, this needs a bit more more effort
than a mere switchover to xmlto.
The top-level directory structure imposed by publican is kept for now
(specifically the Wayland/en-US/html tree). This makes it easier to transition over
for packagers. Note that the list of files inside has changed.
CSS files are taken from publican to keep a uniform look compared to previous
documentations. Stylesheets are licensed under CC0 1.0 Universal license, see

Same reason as commit cd31275f28b0a04d2ec5426dc81e875197b47e52 from weston:
The scanner needs to be good enough. If it crashes or fails to report
invalid input, that needs to get fixed.
If posix_fallocate is available, use it instead of ftruncate. Unlike
ftruncate, when posix_fallocate succeeds, it guarantees that you cannot
run out of disk space, when later writing to the mmap()'ed file.
With posix_fallocate, if os_create_anonymous_file() succeeds, the
program cannot get a SIGBUS later from accessing this file via mmap. If
there is insufficient disk space, the function fails and errno is set to
ENOSPC.
This is useful on systems, that limit the available buffer space by
having XDG_RUNTIME_DIR on a small tmpfs.

The scanner is not very forgiving if the protocol doesn't match it's
expectations and crashes without much of a notice. Thus, validate the protocol
against a DTD.
Move the protocol subdir forward so we validate first before trying anything
else, and install the DTD so we can validate weston's protocols as well.
