Log Message:
Properly define XTHREAD_CFLAGS/XTHREADLIB on NetBSD:  We do not
want -pthread in XTHREAD_CFLAGS, as this will end up linking everything
against libpthread.  Thus, in keeping with our gcc specfile, define
_REENTRANT in XTHREAD_CFLAGS instead.  XTHREADLIB is now
-pthread, not -lpthread.

While here, update to head of libX11-1.1 branch in GIT (with the
exception of some unicode changes which caused mkpatches to choke).

changes:

 - IM: Respect XMODIFIERS for Thai locale (bug #15719)
 - Bug #15884: Remove useless sleep()'s from the connection code.
 - NLS: Make UTF-8 the default for Russian
 - ConnDis: properly cast 'addr' before accessing it as a byte array.
 - added error check in Xcms color file parser; closes bug #15305
 - Fix missing error condition in cmsColNm.c, also.

Bump PKGREVISION.
