50b1097643 Constify the reason string throughout the authorization check framework
Almost all of the places the string is assigned point to a literal
string constant, so use const char * for those, and const char **
for function calls that return it via an argument.   Fortunately
the top level function, ClientAuthorized, which returns the string
as its return value is called from only one place, ProcEstablishConnection.

ProcEstablishConnection stores either that return value or a string literal
in char *reason.  It only uses reason as an argument to SendConnSetup.
SendConnSetup passes the reason argument to strlen & WriteToClient,
both of which already have const qualifiers on their args.
Thus added const to the reason variable in ProcEstablishConnection
and the reason argument to SendConnSetup.

Fixes gcc warnings:
dispatch.c: In function 'ProcEstablishConnection':
dispatch.c:3711:9: warning: assignment discards qualifiers from pointer target type

9999819601 Constify string for authorization protocol names
gcc was warning from storing string constants in a char *name field:
auth.c:64:1: warning: initialization discards qualifiers from pointer target type
auth.c:72:1: warning: initialization discards qualifiers from pointer target type
auth.c:81:1: warning: initialization discards qualifiers from pointer target type

Making the field const requires changing AuthorizationFromID to take
a const char ** pointer for the name argument which it sets to point
to the matching name entry.

Changing that argument requires changing its sole caller in the security
extension to pass the address of a const char * variable to it, which it
can do, since the only thing it does with the returned name is to pass
it back to the RemoveAuthorization function that already expects a const
char *name.

8b6a750097 Fix gcc warnings about redundant declarations of fallback functions
Ensure ffs, strndup, strlcat, etc. aren't defined by our headers
if they're already defined in the system headers.

This does export the HAVE_FFS, HAVE_STRNDUP, etc. definitions to drivers,
but if you built the Xserver with a libc that had those, and then build
the drivers with a less capable libc, you're going to have problems anyway,
and this should solve some reported problems with conflicts between our
strndup definition and gcc magic for it.

4be68b0312 Remove unused function checks from configure.ac & include/*.h.in
The code that used getisax to check for MMX support was moved to pixman
and removed from the X server by commit eb2d7fe02f.

The code that used HAVE_MKSTEMP was deleted by the Xprint removal in
commit 1c8bd318fb.

All alloca calls were removed by the patch series end in commit 5e363500c8,
and used custom X checks instead of the autoconf HAVE_ALLOCA anyway.

I can find no record of HAVE_GETUID, HAVE_GETEUID, HAVE_LINK, HAVE_MEMMOVE,
HAVE_MEMSET, HAVE_STRCHR, HAVE_STRRCHR, HAVE_GETOPT, HAVE_GETOPT_LONG,
HAVE_DOPRNT, or HAVE_VPRINTF ever being used, and the calls to those
functions are not wrapped in #ifdefs.
(Most of those are in our baseline requirements of C89 & Unix98 anyway.)

fb22a408c6 Save major/minor opcodes in ClientRec for RecordAReply
The record extension needs the major and minor opcodes in the reply
hook, but the request buffer may have been freed by the time the hook
is invoked. Saving the request major and minor codes as the request is
executed avoids fetching from the defunct request buffer.

This patch also eliminates the public MinorOpcodeOfRequest function,
inlining it into Dispatch. Usages of that function have been replaced
with direct access to the new ClientRec field.

9c38422fc4 include: add BUG_WARN macro for internal bug cases.
There are plenty of cases that can only be triggered by a real bug in the
server and doing the ErrorF dance manually everywhere is a tad painful and
the error message is usually used only to find the spot in the file anyway.

Plus, reading BUG_WARN somewhere is a good indicator to the casual reader
that this isn't intended behaviour.

Note that this is intentionally different to the BUG_ON behaviour on the
kernel, we do not FatalError the server. It's just a warning + stacktrace.
If the bug is really fatal, call FatalError.
