Xwin's DestroyPixmap proc just free()s the PixmapRec directly, w/o catering
for devPrivate's, so leaving a memleak. The correct DIX function for this
is FreePixmap().

$ 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

This header includes libxfont2.h, but the dependency isn't stated anywhere,
causing some drivers to FTBS (when libxont2.h is in non-standard location).
Since this header doesn't seem to need including libxfont2.h at all, just
stop including it, instead of adding yet another dependency to server SDK.

The old PCCONS driver only seems to be used on minimal install disks and
cannot coexist with newer ones, so there's probably no practical use case for
supporting it in Xorg anymore.

PANORAMIX was the original working title of the extension, before it became
official standard. Just nobody cared about fixing the symbols to the official

Both xlib as well as the Xserver use the same identifier "GC" for
different types. While on xlib it's just the numerical ID of a GC,
the xserver defines a struct for it by the same name. This is this
ugly and needs ridiculous hacks for Xserver code that needs xlib.
Easy to solve by just renaming the GC typedef to GCRec (consistent
with how we're naming other structs) and replacing GC* by GCPtr.

The functions declared here aren't used by any driver, so no need to keep
them in the public driver API. Since the whole file isn't included by anybody
outside the xserver tree itself, it doesn't need to be installed at all,
so making it internal and move it to Xi directory.

These functions shouldn't be called by drivers or extensions, thus

already huge ones aren't cluttered with even more things.

DEV_MEM define isn't used by any drivers, and BSD seems to be the only
platform using /dev/pmem instead of /dev/mem - as well as the DEV_MEM
define from xf86_OSlib.h (Linux uses the symbol, but defines on its own)
Therefore, just define it where actually used and drop it from the global
xf86OSlib.h file.
Note that /dev/pmem refers to physical memory, not to be mixed up with
Linux's persistent memory subsys, which uses /dev/pmem[N] device nodes.

These have been forgotten on some major cleanup back almost two decades ago.
(Daniel dropped a lot of dead code, which already had been removed earlier
but merged back accidentially).
Didn't look further back on where exactly they had become obsolete - being
unused for decades should be enough justification for dropping.

The symbol controls whether to include dix-config.h, and it's always set,
thus we don't need it (and dozens of ifdef's) anymore.
This commit only removes them from our own source files, where we can
