Update from 1.3.5 to 1.5.0 based on PR pkg/46183

 [ANNOUNCE] libX11 1.5.0
------------------------
 At long last, the stable release of Xlib 1.5.0.

 While it only strictly requires libxcb 1.2, it's recommended that libxcb 1.8.1
 be used to get the fix for network connection fallback from Unix sockets to
 TCP that replaces the code previously found in libX11.

 Since there have been no changes since the final release candidate,
 here's the full list of changes since libX11 1.4.4:

[ANNOUNCE] libX11 1.4.4

Thu, 28 Jul 2011 20:05:49 -0700 by  Alan Coopersmith

Another bug fix release of libX11 brings another large set of fixes
found by static analysis or to ease further static analysis, many
documentation fixes and improvments, and improved assertions to
help users and developers figure out why Xlib just crashed on them.

[ANNOUNCE] libX11 1.4.3
-----------------------
Tue Apr 5 14:18:18 PDT 2011 by Alan Coopersmith

A minor release of libX11 to add support for the Sinhala keysyms required
by the recent xkb-config 2.2 release.   Note that to get full support for
these keysyms you will also need to upgrade to x11proto 7.0.21 before
building the new libX11.

[ANNOUNCE] libX11 1.4.2
-----------------------
This bugfix release pulls in a ton of fixes for problems found by code static
analysis tools.  Many thanks to everyone who has helped find and fix these
issues before they turned into nasty problems.

Additionally, Jamey Sharp has provided some fixes for Display lock handling
that caused some deadlocks when using xcb for transport (which was optional
in 1.3.x and is required in 1.4.x), so this update is highly recomended to
users of multi-threaded Xlib applications.

[ANNOUNCE] libX11 1.4.1
------------------------
Tue, 11 Jan 2011 22:35:19 -0800 by Alan Coopersmith

This bugfix release corrects two small issues in Xlib event handling,
and provides, for the first time ever, the XKB API spec in DocBook format.

[ANNOUNCE] libX11 1.4.0
------------------------
Sun Nov 21 14:38:32 PST 2010 by Alan Coopersmith

After 3 release candidates, it's finally done - libX11 1.4 is released.

As previously warned, libX11 1.4 *requires* libxcb.   The Xlib 1.3 branch
continues to support the --without-xcb option for the benefit of any
remaining distributors who do not yet ship XCB in their stable releases.

[ANNOUNCE] libX11 1.3.6
------------------------
2010-09-20 6:16:18 by Daniel Stone

Just a small maintenance release for libX11; pending any catastrophic
bugs, this will probably be the last release from the 1.3.x branch.  The
XStringToKeysym changes should provide a not-insignificant speedup for
X server and application startup.
