Previously, when parsing multiple configuration files containing the same
section names, only the last occurrence of each section would be retained.
Earlier definitions were silently discarded due to unconditional memory
allocation and overwriting of pointers during parsing.
This resulted in incomplete or incorrect configuration state when users
intended to merge or extend configuration through multiple files.
The section parsing functions in Files.c, Flags.c, and Module.c now
accept existing section pointers. These functions allocate new memory only
if the input pointer is NULL, preserving earlier data when re-parsing.
read.c has been updated to detect and pass existing section pointers when
encountering duplicate sections across files, preventing loss of prior content.
With these changes, the parser properly accumulates and merges configuration
data across multiple files, ensuring that all relevant settings are preserved.

$ echo "#foo\nfoo" > custom_config $ X -config custom_config
will trigger the double free because the contents of xf86_lex_val.str
have been realloc()ed aready when free is called in read.c:209.
This copies the lex token and adds all the necessary free() calls to
avoid leaking it
Part-of: <https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/1176>
Add the const notation to all the static storage as well as the
functions that use it - xf86getToken(), xf86getSubTokenWithTab(),
StringToToken() and xf86getStringToken().

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

Previously it always passed a format string with exactly one argument,
using NULL when the format string needed none. Now pass the right number
of arguments to clear gcc warnings of 'too many arguments for format'.

Provide default modules that may be overrided easily. Previously the
server would load a set of default modules, but only if none were
specified in the xorg.conf, or if you didn't have a xorg.conf at all. This
patch provides a default set and you can add only the "Load" instructions
to xorg.conf that you want without losing the defaults. Similarly, if you
don't want to load a module that's loaded by default, you can add "Disable
modulename" to your xorg.conf (see man xorg.conf in this release for
details). This allows for a minimal "Modules" section, where the user only
need specify what they want to be different. See bug #10541 for more.
The list of default modules is taken from the set loaded by default when
there was a xorg.conf containing no "Modules" section.
A potential problem for some users is that some users disable a module,
most notably DRI, by commenting out the "Load" line in their xorg.conf.
This needs to be changed to an uncommented "Disable" line, as DRI is
loaded by default.
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
