d5379b350f Use ARRAY_SIZE all over the tree
Roundhouse kick replacing the various (sizeof(foo)/sizeof(foo[0])) with
the ARRAY_SIZE macro from dix.h when possible. A semantic patch for
coccinelle has been used first. Additionally, a few macros have been
inlined as they had only one or two users.

1549e30372 Add a Meson build system alongside autotools.
This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far.  The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet.  The unit tests are also not done.

The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools.  meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

v2: Fix indentation nits, move version declaration to project(), use
    existing meson_options for version-config.h's vendor name/web.

c7be7a688a Use #ifdef instead of #if for features to make Meson easier.
We mostly use #ifdef throughout the tree, and this lets the generated
config.h files just be #define TOKEN instead of #define TOKEN 1.

8920dca009 loader: Remove unused arguments from LoadModule
Nobody was ever calling this with a non-null argument for subdir list or
pattern list.  Having done this, InitSubdirs is only ever called with a
NULL argument, so it's really just a complicated way of duplicating the

The minor error code was only ever used to distinguish among two cases
of LDR_BADUSAGE. Whatever.

write to the interface not to the OS.  There are a couple of drivers

This also removes the OS name from the loader subdirectory path search.

b5dffbbac1 xfree86: Add ModulePath support for OutputClass config Sections
Allow OutputClass config snippets to modify the module-path.

Note that any specified ModulePaths will be pre-pended to the normal
ModulePath. The idea behind this is that any output hardware specific
modules should have preference over the normal modules.

One use-case for this is the nvidia binary driver, this allows a
config snippet like this:

Section "OutputClass"
    MatchDriver "nvidia"
    Modulepath "/usr/lib64/nvidia/modules"
EndSection

To get the nvidia glx specific glx module loaded, but only when the
nvidia kernel driver is loaded.

Together with the glvnd work done recently, this allows the nouveau
+ mesa and nvidia-binary userspace stacks to co-exist on the same
system without any ldconfig / xorg.conf tweaking and the xserver will
automatically do the right thing depending on which kernel driver
(nouveau or nvidia) is loaded.

258abbf823 Look for ModuleData only in appropriate library
LoaderSymbol calls dlsym with RTLD_DEFAULT pseudo handle making it search in
every loaded library. In addition glibc adds NODELETE flag to the library
containing the symbol.

It's used in doLoadModule to locate <modulename>ModuleData symbol, the
module's library gets the flag and is kept in memory even after it is
unloaded.

This patch adds LoaderSymbolFromModule function that looks for symbol only in
library specified by handle. That way the NODELETE flag isn't added.

This glibc behavior doesn't seem to be documented, but even if other
implementations differ, there is no reason to search ModuleData symbol outside
the module's library.
