Jamey Sharp ee1bc1d28a xcb_send_request: Send all requests using a common internal send_request. 
This simplifies the critical section of xcb_send_request and fixes a
couple of subtle bugs:

- It's possible for xcb_send_request to need to issue two sync requests
  before it can issue the real request. Previously, we counted sequence
  numbers as if both were issued, but only one went out on the wire.

- The test for whether to sync at 32-bit sequence number wrap has been
  incorrect since we switched to 64-bit sequence numbers internally.

This change means that if the output queue was already full and the
current request is bigger than the output queue, XCB will do one more
write syscall than it did before. But syncs are rare and small requests
are the norm, so this shouldn't be a measurable difference.

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.
