Christian Beier 49cdfb4c1f libvncclient: better return value for non-forking listen.
The return value now better reflects what has happened:
1 on success (incoming connection on listen socket, we
accepted it successfully), -1 on error, 0 on timeout.

Also change the select calls to not check _all_ possible
file descriptors.

Christian Beier 0a4f1bada4 libvncclient: add a non-forking listen function.
Forking the whole process from deep within a library call does
not really work at all with apps that use multiple threads, i.e. every
reasonably modern GUI app. So, provide a non-forking listen function so
that the caller can decide if to fork, start a thread, etc.

This implementation adds a timeout parameter to be able to call the
listen function multiple times so that it's possible to do sth. else
in between, e.g. abort listening.

Alexander Dorokhine 62ae6bb7be libvncclient: Add FinishedFrameBufferUpdate callback
When working on a program which searches the display for some image, one
does not want to search again without getting an FB update.  Add a
callback to make this possible.

Christian Beier a92f7f46a6 mingw32 crosscompile fixes.
SOCKET is redefined in winsock2.h so #undef it where winsock2.h
is included. The changes in rfbproto.c circumvent crosscompiler
errors like 'S_IFMT' undeclared ...', the Makefile.am changes
avoid building linux specific stuff for a win32 host target.
Also added configure option to specify sdl-config.

dscho 8641c8e7bf Fix compilation in the absence of libjpeg
The JPEG library is not necessarily installed everywhere, and sometimes
it is outright undesirable to compile with JPEG support, e.g. when the
server is not very fast.  So fix the compilation for that case.

dscho 3d9a563983 Move tightQualityLevel out of the JPEG specific part
The variable tightQualityLevel is used for ZYWRLE compression, too,
so if libjpeg is not present, but libz is, we still need to have
that struct member.

dscho ce8d6c2409 Make ZYWRLE thread-safe for multiple clients
ZYWRLE used a static buffer, which does not work too well if you have
more than one client in a threaded server.  Instead, we have the data
in the client structure now.

dscho 951ec26b7c The PseudoEncoding extension code was getting silly:
If the client asked for an encoding, and no enabled extension handled it,
LibVNCServer would walk through all extensions, and if they promised to handle
the encoding, execute the extension's newClient() if it was not NULL.

However, if newClient is not NULL, it will be called when a client connects,
and if it returns TRUE, the extension will be enabled. Since all the state of
the extension should be in the client data, there is no good reason why
newClient should return FALSE the first time (thus not enabling the extension),
but TRUE when called just before calling enablePseudoEncoding().

So in effect, the extension got enabled all the time, even if that was not
necessary.

The resolution is to pass a void** to enablePseudoEncoding. This has the
further advantage that enablePseudoEncoding can remalloc() or free() the
data without problems. Though keep in mind that if enablePseudoEncoding()
is called on a not-yet-enabled extension, the passed data points to NULL.
