Michel Dänzer f85661c3bc Call _xcb_wake_up_next_reader from xcb_wait_for_special_event 
All functions calling _xcb_conn_wait() must make sure that waiting
readers are woken up when we read a reply or event that they are waiting
for. xcb_wait_for_special_event() did not do so. This adds the missing
call to_xcb_in_wake_up_next_reader().

Fixes deadlock when waiting for a special event and concurrently
processing the display connection queue in another thread.

About libxcb
============

libxcb provides an interface to the X Window System protocol, which
replaces the current Xlib interface. It has several advantages over
Xlib, including:
- size: small, simple library, and lower memory footprint
- latency hiding: batch several requests and wait for the replies later
- direct protocol access: interface and protocol correspond exactly
- proven thread support: transparently access XCB from multiple threads
- easy extension implementation: interfaces auto-generated from XML-XCB

Xlib can also use XCB as a transport layer, allowing software to make
requests and receive responses with both, which eases porting to XCB.
However, client programs, libraries, and toolkits will gain the most
benefit from a native XCB port.


Please report any issues you find to the freedesktop.org bug tracker,
at:

	<https://bugs.freedesktop.org/enter_bug.cgi?product=XCB>

Discussion about XCB occurs on the XCB mailing list:

        <mailto:xcb at lists.freedesktop.org>

You can obtain the latest development versions of XCB using GIT.
