Move general FLTK stuff to own directory
Let's separate TigerVNC specific things from stuff that could be part of
upstream FLTK. These are files that we would like to collaborate with
other FLTK users, so they are more liberally licensed and avoid using
TigerVNC specific things.

Use BufferedOutStream in more streams
Avoid duplicating all the memory mangement, and instead use the
BufferedOutStream as a base clase for all out streams that need an
intermediate buffer.
This commit changes the color of the edges of the dot cursor in the Java
version of vncviewer from fully transparent to white, bringing it in
line with the C++ native version.

Fix Xvnc dependency list (again)
The previous commit was incorrect in that it overrides automake's
dependency list, rather than adding to it. So we need to make sure
things are duplicated between Xvnc_DEPENDENCIES and Xvnc_LDADD as
appropriate.
Use the same approach as the Xorg binary to keep things familiar.

These aren't crucial for a clean build, but must be set for Xvnc to be

Safely discard large (extended) clipboard contents
Avoid having to buffer everything we want to discard, and instead do it
piece by piece. This is more efficient, and avoids hitting any limits on
the buffering.
Note that this is safe here because we already know we have all the
compressed data. It would not be safe for a general input stream.

Properly restore cork state when changed
These streams both need to change the corking state temporarily, but it
is important it is restored to the previous state or things might get
messed up.
For the zlib stream it would just leave things uncorked, which still
works but is less efficient.
But for the TLS stream it might make things very unresponsive as the
corking might be left on permanently, delaying packets indefinitely.

Workaround for MFT cropping in H264 decoding
It seems MFT h264 decoder does not support frame cropping. Which
means that if frame width or height is not multiple of 16 then
decoded output can potentially be used with wrong offset. This
code adds explicit parsing of SPS to extract cropping information
to use, and will apply cropping if reported size differs from
expected.

Ignore socket whilst processing data
FLTK has a lot of synchronous stuff (like dialogs), which mean that the
main loop might be run recursively in some cases. If there is data
available on our socket then CConn::socketEvent() will be called
constantly in a busy loop.
Avoid this by removing socket notifications whilst we are processing
data.

Fix session resize after mirroring on Linux vncviewer
If monitor mirroring was enabled while in a session with vncviewer
running on Linux, the session would not be properly resized on the
server. This was a consequence of only looking at the size and
coordinates of each screen when matching against existing screens after
the screen layout was changed, when in fact we have two (or more)
monitors with the same coordinates and size (but differing ids). This
led to the same monitor being added twice to the layout which would
later fail layout validation, resulting in no resize request being sent
to the server.
When matching, we now also check if the existing screen is not already
present in the layout before considering it a match.

Improve full-screen workaround on connect
If we've explicitly requested a position (using -geometry) then we were
still triggering legacy full-screen request logic. This is very counter
intuitive as having a position that doesn't align with a monitor should
disqualify us for that.
It turns out that at least marco (and probably everything
metacity-derived) ends up ignoring the requested position and we go back
to triggering the legacy logic again.
Work around this by assuming that the window manager will adjust our
initial position and don't consider that in the workaround logic.

Update MonitorArrangement widget after change
If the options dialog was open when a screen configuration happened the
widget could get out of sync from the settings. A scenario when this
happened was:
1) 3 monitors, fullscreen selected on the two right-most screens
2) disconnect the left-most screen (the one not selected)
In this case, using GNOME, vncviewer would appear in fullscreen on the
right of the two remaining monitors, but the widget would show both
monitors selected. The reason was that the MonitorArragement index
doesn't work the same way as FLTK's screen index.
It's debatable how vncviewer should behave here, but the GUI should at
least match the actual setting.
