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.

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.

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.
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.
