This was part of "An experimental pseudocolor emulation layer. Not fully
completed, currently only works for 16bpp." Only neomagic tried to use
it, and that was neutered by the removal of the fbpseudocolor portion of
that emulation layer; the rest is easily removed.

This reverts commit 9120e58556.
Whoops, please revert this patch -- overlay is in use in nvidia drivers,
and it's too late in release cycle to remove it.
I feel really sorry that I kept this patch in my tree. I will submit
another one, removing only XAA overlay hooks which are not used at all.
The only reference to it in server and drivers is in XAA overlay code which
would segfault as no miInitOverlay is called ever. No segfaults were observed
"in wild", so XAA overlay is probably also unused.
XAA code is modified to act as if miOverlayCopyUnderlay always returned false,
because XAACopyWindow8_32 could only set doUnderlay to true if it's called from
miOverlayMoveWindow or miOverlayResizeWindow, which can only be called if
miInitOverlay has hooked those functions, and no driver (on fd.o) or server code
calls that.

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.

Banked framebuffers are so 1990. As of 7.4 the only drivers remaining
that used this were chips, neomagic, trident, and vesa. vesa only used
it when not using shadowfb, which is broadly undesirable anyway, and no
longer uses it at all as of 2.3.0. neomagic never used it by default,
and support for it is gone in git master. The other two effectively
only ever used it for ISA chips; since ISA support is now gone from
the server, they have been modified to only compile mibank support when
ISA support is available.

FindModuleInSubdir seems to expect a / at the end of the subdir its
finding for, so we add the / early, the stat will fail if its
not a subdir, I'm leaving the S_ISDIR in just in case there is another
reason it could return 0. This does look a bit silly in strace
but it seems to work fine.
I have a very intermittent issue where drivers loses its / that
I've been seeing on/off for a while, this may or may not fix it.

In the X log, upon module load, it prints a line similar to the following.

The attached patch removes the extra / before the module name.
Code already exists in hw/xfree86/loader/loadmod.c:InitPathList to add a
trailing slash if needed, removing the one added by sprintf is harmless.

Since it is already parsing cpp output, create a dependency file
in the same process. This will cause sdksyms.c to be regenerated
whenever a sdk header is modified.
This also uses the gmake 'sinclude' directive (don't fail if
included file doesn't exist). This should not cause any problems
given that gmake only constructs are used in several other Makefiles.
- Pass $(CPP) & $(AWK) settings from configure to sdksyms.sh
- Only reset sdk variable (tracks if header is part of sdk) if
a filename is included on the cpp # <line-no> <filename> line,
since Sun compilers omit filename when it is unchanged from
previous line.
Ubuntu uses mawk by default, but it doesn't understand posix character
classes (which are locale dependent, and this patch uses only valid C
identifiers).
Also make sure awk runs with LC_ALL=C to match the regex patterns.
If the basename of header file processed by cpp matches $top_srcdir,
check for extern symbols in the output, and add to the xorg_symbols
vector.
Possibly a better solution then using this script would be to somehow
tell the linker to not drop any symbols from the binary being generated.
Thanks to David Miller for noticing a make problem with sdksyms.c
not being regenerated when sdksyms.sh is updated. This is not yet the
best solution; automake generates dependency for sdksyms.o, but the
build really should also regenerate sdksyms.c when sdksyms.o needs to
be regenerated.
Export the symbols in miext/cw/cw.h. These symbols are in libxaa, and
at least the nvidia driver uses them. Maybe cw.h should be installed
in the sdk.
The awk script was incorrectly referencing the struct name, and
not the struct variable.
Also added some comments to sdksyms.sh, for the reason it generates
the "symbol table" and add a message to the generated file, telling
is was automatically generated.
Traditional posix awk doesn't know about \W and whilst we check that
awk exists in configure.ac we don't check which awk we are using.
This corrects symbol generation for posix only awk.
All .a libraries were converted to .la, and instead of linking the
Xorg binary with a mix of .a and .la, and adding some libraries more
then once in the command line, etc, now it generates a single libxorg.la
from all the required convenience libraries, and links with a dummy
xorg.c (that should usually be the file with the main function...).
This removes the requirement of some things like libosandcommon and
libinit, that existed to circumvent problems when linking multiple
.a and .la in the final Xorg binary.
The "symbol table" is now generated dynamically, by a shell script,
with an embedded gawk parser that parses cpp output. The new file
sdksyms.sh is generated by hand by analyzing all Makefile.am's and
making it create a sdksyms.c file, that includes all sdk headers that
will add symbols for the Xorg binary. Module headers aren't read, and
a in 2 files it was required to add a "<hash>ifndef XorgLoader" around
declarations shared between the Xorg binary and libextmod. A few
other changes were added to other sdk headers, like preventing
multiple inclusion, or including other headers to satisfy dependencies.
This should be a lot more portable, and better (hopefully properly)
using libtool to generate convenience libraries.
If not taking the symbol addresses, linkage will break badly, as not
all symbols will be present, and it also requires changing library order,
and/or making some changes like the "libosandcommon".
This table should be modified to be generated automatically, as
it is required to "fool" the compiler/loader into adding all required
symbols to the X Server.
