Enrico Weigelt, metux IT consult 09af7f6a5b xnest: replace xallocarray() by calloc()
Only key difference that calloc(), in contrast to rellocarray(),
is zero-initializing. The overhead is hard to measure on today's
machines, and it's safer programming practise to always allocate
zero-initialized, so one can't forget to do it explicitly.

Cocci rule:

    @@
    expression COUNT;
    expression LEN;
    @@
    - xallocarray(COUNT,LEN)
    + calloc(COUNT,LEN)

Enrico Weigelt, metux IT consult bef80a0db9 Xnest: drop special hack for Xlib's GC type
Now that the name clash on GC type between Xserver and xlib has been fixed,
there's no need to do the special renaming hack anymore.

This file became pretty no-op, just including dix-config.h.
So we can remove it now and include dix-config.h directly.

Since we really don't need more than 2^16 colormaps, using uint16_t here
to silence this warning.

Enrico Weigelt, metux IT consult 6dafe3dbe6 drop remains of support for old Sun compilers
With transition from autoconf to meson, these aren't actually supported
anymore, and re-adding it isn't planned. Thus the now dead code pathes
can be completely removed.

Keith Packard 9838b7032e Introduce a consistent coding style
This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:

	-bap
	-psl
	-T PrivatePtr
	-T pmWait
	-T _XFUNCPROTOBEGIN
	-T _XFUNCPROTOEND
	-T _X_EXPORT

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.

The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.

The comparison was done with this script:

dir1=$1
dir2=$2

for dir in $dir1 $dir2; do
	(cd $dir && find . -name '*.o' | while read file; do
		dir=`dirname $file`
		base=`basename $file .o`
		dump=$dir/$base.dump
		objdump -d $file > $dump
	done)
done

find $dir1 -name '*.dump' | while read dump; do
	otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
	diff -u $dump $otherdump
done

Alan Coopersmith c19c55a93a Fix builds of Xnest & Xephyr with Solaris Studio compilers
Required in order to build with Studio cc now that xorg-macros is
setting -errwarn=E_FUNC_HAS_NO_RETURN_STMT since a bug in the Solaris
system headers causes the noreturn attribute to not be correctly
applied to the exit() prototype in <stdlib.h> when building with
Studio instead of gcc.

Otherwise compiler exits with errors:
"Display.c", line 65: Function has no return statement : x_io_error_handler
"hostx.c", line 341: Function has no return statement : x_io_error_handler

Uses Studio-specific pragma instead of adding another exit() prototype
with a noreturn attribute to avoid causing gcc to warn about having
a redundant prototype for the exit() function.

Mikhail Gusarov 3f3ff971ec Replace X-allocation functions with their C89 counterparts
The only remaining X-functions used in server are XNF*, the rest is converted to
plain alloc/calloc/realloc/free/strdup.

X* functions are still exported from server and x* macros are still defined in
header file, so both ABI and API are not affected by this change.
