This update makes the example work on versions of ffmpeg newer than "ancient," fixes a bunch of bugs in the process, and with better documentation of the pitfalls.
Since autotools officially is no longer supported (see various github
issues), drop the related infrastructure to stop tempting people to use
it for building.

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

Keys got stuck because unicode is 0 upon SDL_KEYUP events, even if the
same key event sets unicode correctly in SDL_KEYDOWN events.
Work around that for the common case (ASCII) using the fact that both SDL
and X11 keysyms were created with ASCII compatibility in mind. So as long
as we type ASCII symbols, we can map things trivially.

Besided making libvncserver reverseVNC IPv6-aware, this introduces some changes
on the client side as well to make clients listen on IPv6 sockets, too. Like
the server side, this also uses a separate-socket approach.
I think it may encourage people to implement more features for the viewer,
because a GTK GUI seems to be easier to implement than a SDL one
(and it is more integrated with the major Linux Desktops out there).

I got annoyed having to specify -resizable all the time; I never use it in

Adds automagically generating libvncserver/libvncclient API
documentation using doxygen. This gives a nice overview on both APIs,
include dependencies and function call/caller dependencies.
TODO: Modify all the explaining comments in the .c files for use with
doxygen as well.
This patch only changes comments, no functional changes at all!

set the port to listen on and really ensure that the
window of the fork()ed instance is closed.
works somewhat: it's now actually possible to listen for an
incoming connection and to close it again, but the second
connection attempt fails with 'XIO: fatal IO error 11
(Resource temporarily unavailable)'. this could relate to the
fact that SDL uses threads internally and we're fork()ing
here...

Instead of having deep indent levels, put the code to handle events into
its own function. That also helps readability.

Using "SDLvncviewer -resizable", you make the window resizable. This
means that you can shrink the window (e.g. when you are trying to access
an x11vnc from your little netbook), or you can enlarge it.

The flag handling (both compiler options and include paths) are a mess at
the moment. There is no point in forcing "-O2 -g" when these are already
the defaults, and if someone changes the defaults, chances are good they
don't want you clobbering their choices.
The -Wall flag should be handled in configure and thrown into CFLAGS once
rather than every Makefile.am. Plus, this way we can control which
compilers the flag actually gets used with.
Finally, the INCLUDES variable is for -I paths, not AM_CFLAGS. Nor should
it contain -I. as this is already in the default includes setup.
