This topic branch provides compatibility for Windows, without the
MINGW32 dependency.
It is based on https://github.com/LibVNC/libvncserver/pull/22.

With Microsoft Visual C++, we cannot use pthreads (MinGW sports an
emulation library which is the reason we did not need Windows-specific
hacks earlier). Happily, it is very easy to provide Windows-specific
emulations for the pthread calls we use.

Microsoft Visual C++ does not allow pointer arithmetic on void pointers.

To support Microsoft Visual C++, we must not guard Windows-specific code
in MinGW-specific #ifdef guards.
Happily, even 64-bit MSVC defines the WIN32 constant, therefore we can use
that instead.

The stdint.h file was copied from:
https://runexe.googlecode.com/svn-history/r9/trunk/src/runlib/msstdint.h
(we can incorporate it because it is licensed under the 3-clause BSD
license.)

In Microsoft's Visual C runtime, the snprintf() function is actually
called _snprintf. Let's just #define the former to call the latter.

We link to ws2_32.lib which corresponds to the winsock2.h header, not the
winsock.h header.

This change is technically not required to support MSVC, but it was
detected by Microsoft's compiler.

If MallocFrameBuffer() returns FALSE, frame buffer pointer is left to
NULL. Subsequent writes into that buffer could lead to memory
corruption, or even arbitrary code execution.
check_xrandr_event() assumes X_LOCK is taken before it is called, and
currently calls X_UNLOCK on behalf of the caller. But in practice, all
callers assume that the lock is still held after check_xrandr_event()
returns. In particular, this leads to a double-unlock and crash in
check_xevents() on any xrandr event.

This makes the library friendly to use as a git submodule within another
project, and should change nothing when compiled alone.
For example when having a directory structure like "my_project/external/libvnc",
where in libvnc resides a checkout of libvncserver, one can just reference that
directory from the CMakeLists.txt in my_project with
> add_directory ( external/libvnc )
and add vncclient / vncserver in my_project's taret_link_libraries, one can just
hack away without having to manually make / install LibVNCServer whenever
something is changed there.
Since we connected to the client through the repeater, chances are
that we want this server shut down once the client disconnected.

UltraVNC offers an add-on to connect clients and servers via IDs with
a so-called repeater (e.g. to bridge firewalled clients and servers):

This example demonstrates how to use that feature with a
LibVNCServer-based server.

rfbClientSetClientData() allocates a new rfbClientData, but never gets
cleaned up, which causes memory leaks.

This patch implements support in LibVNCClient for framebuffer updates
encoded as H.264 frames. Hardware accelerated decoding is performed
using VA API.
This is experimental support to let the community explore the possibilities
offered by the potential bandwidth and latency reductions that H.264 encoding
allows. This may be particularly useful for use cases such as online gaming,
hosted desktops, hosted set top boxes...
This patch only provides the client side support and is meant to be used
with corresponding server-side support, as provided by an upcoming patch for
qemu ui/vnc module (to view the display of a virtual machine executing under
QEMU).
With this H.264-based encoding, if multiple framebuffer update messages
are generated for a single server framebuffer modification, the H.264
frame data is sent only with the first update message. Subsequent update
framebuffer messages will contain only the coordinates and size of the
additional updated regions.
Instructions/Requirements:
* The patch should be applied on top of the previous patch I submitted with
minor enhancements to the gtkvncviewer application:
http://sourceforge.net/mailarchive/message.php?msg_id=30323804
* Currently only works with libva 1.0: use branch "v1.0-branch" for libva and
intel-driver. Those can be built as follows:
cd libva
git checkout v1.0-branch
./autogen.sh
make
sudo make install
cd ..
git clone git://anongit.freedesktop.org/vaapi/intel-driver
cd intel-driver
git checkout v1.0-branch
./autogen.sh
make
sudo make install
