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

01834e99e4 os/access.c: replace acmp & acopy macros with memcmp & memcpy calls
No need to cast to char * now that all supported platforms use C89-standard
void * argument types, so just drop the casts from acmp & acopy macros,
which clears the gcc warnings for places const pointers were cast non-const:

access.c: In function 'DefineSelf':
access.c:786:3: warning: cast discards qualifiers from pointer target type
access.c:795:6: warning: cast discards qualifiers from pointer target type
access.c: In function 'NewHost':
access.c:1293:9: warning: cast discards qualifiers from pointer target type
access.c:1298:6: warning: cast discards qualifiers from pointer target type
access.c:1309:5: warning: cast discards qualifiers from pointer target type

Without the casts, acmp & acopy are just a funny way to write memcmp
& memmove, so drop the macros and inline the calls, taking care to
swap the first two arguments to memmove since it had swapped them.

Since all the calls to memmove end up being to non-overlapping memory
(mostly copying from an existing pointer to a newly allocated one),
replace those with memcpy.

And finally, don't actually call memcpy to copy 0 bytes from one place
to another, since that's just a waste of a perfectly good function call.

660f6ab549 Don't crash when asked if a client that has disconnected was local
ProcDRI2Dispatch uses LocalClient to determine if it's safe to respond
to a client that has made DRI2 requests which aren't sensible for
remote clients (anything but version). When the client has disappeared
mid-request stream (e.g. as a result of a kill -9, or a client-side
bug), LocalClient causes the X server to follow suit, as
((OsCommPtr)client->osPrivate)->trans_conn is NULL at this point.

The simple and obvious fix is to just return "not local" when
trans_conn is NULL, which fixes the crash I was seeing; however Keith
Packard pointed out that just checking trans_conn isn't enough;
quoting Keith:

"This looks almost right to me -- I reviewed the os code to see when
_XSERVTransClose is called (which is what frees the trans_conn data) and
found that every place which called that immediately set trans_conn to
NULL, except for the call in CloseDownFileDescriptor which is only
called from CloseDownConnection and which is immediately followed by
freeing the OsCommRec and setting client->osPrivate to NULL. So, I'd
suggest checking client->osPrivate in addition to the above check."

e42a29d269 Fix compiler issues with getifaddrs() call on OpenSolaris
OpenSolaris recently added support for the getifaddrs() API.

"access.c", line 768: warning: argument #1 is incompatible with prototype:

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.

75b9383d8a xserver doesn't stop all connections to localhost
X.Org Bugzilla #23329: http://bugs.freedesktop.org/show_bug.cgi?id=23329
Patch #28648: http://bugs.freedesktop.org/attachment.cgi?id=28648

I noticed in xserver at os/access.c that xorg tries to stop connections
to localhost by checking against the address 127.0.0.1.  However, RFC
3330 defines the localhost network as 127.0.0.0/8.  This means that any
IPv4 address that starts with 127 is just another name for localhost.

49f77fff14 Rework symbol visibility for easier maintenance
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.

  This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)

  LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.

  xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).

d6cbd4511e Export symbols defined in the sdk.
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.

  Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.

  Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:
