Major restructuring of how streams work. Neither input nor output
streams are now blocking. This avoids stalling the rest of the client or
server when a peer is slow or unresponsive.
Note that this puts an extra burden on users of streams to make sure
they are allowed to do their work once the underlying transports are
ready (e.g. monitoring fds).
Provides safety against them accidentally becoming negative because
of bugs in the calculations.
Also does the same to CharArray and friends as they were strongly
connection to the stream objects.
Make socket writes non-blockable. This allows the system to more quickly
return back to the Xorg main loop, meaning that things will be more responsive
in the presence of slow VNC clients.

Removed the FdOutStream::writeBytes() implementation as the same
method of the parent class seems to do the work better. The function
can flush buffered data even if there were only a few bytes in the
buffer. That results in sending packets with just 1 byte of data,
while encoding data with 32-bit Hextile.
