The norm is that the install target is read only from the point of view
of the source and build directory, so avoid accidentally triggering any
build.

file each time.

FLTK can send events with fl_xevent pointing to random memory, which
means that we cannot trust that structure. XQueryPointer() can give us
what we need, at the cost of an extra round trip.

That extra add_fd() only set the read notification, overwriting any
write notification set up in the lines just above.

Primarily to avoid the versions that are now deprecated.

GnuTLS seems to have dropped grypt support ages ago, so let's not
confuse things by assuming it might be needed when linking GnuTLS
statically.

Although unlikely, there might be other parts of the X server that are
also interested in this call. Make sure we propagate things on properly.

It doesn't just control button events, but all types of pointer events,
including movement.

The MIT-SHM documentation:
https://www.x.org/releases/X11R7.7/doc/xextproto/shm.html
says to run XShmDetach() first, and then to destroy the segment.

Mouse events in shared connections are locked to one viewer at a time.
If the a mouse drag is happening in the first viewer, the second viewer
can't interfere unless the first viewer has been inactive for a set
amount of time. This timeout was put in place in
71c83b479335337b25dc331d3fb4a6e29382ceb5 to handle the case where the
first viewer disconnects while the mouse drag is happening. Prior to the
timeout, this resulted in all input being blocked.
This commit increases this timeout from 3 seconds to 10 seconds. This is
to minimize the risk of this happening during "normal" use. With this
change, the first viewer has to be inactive for 10 seconds before the
second viewer can take control again.
In the case where the first viewer disconnects, a waiting time of 10
seconds for the second viewer seems very reasonable.

VNCServerST: Add a timeout to pointer button ownership

When one clients holds down a button on the pointer device (probably
dragging something), other clients' attempts at pointer operations
are denied. This yields a sane user experience, but with limits.
When one clients starts dragging, and then his network connection fails,
other clients are denied access to the pointer until the VNC server
finally discovers that the connection is dead and closes it. This can
take about 15 minutes.
Add a timeout to this policy: If we don't hear from the client for 3
seconds, other clients are allowed to control the pointer once more.
This solves the problem that one failing network could make the server
completely deaf to other clients for a long time.

The common use case is probably to only listem to the systemd provided
socket when using socket activation, but it might not be the only use
case. Make sure things can be combined if explicitly requested.

Avoid magical numbers as it makes it hard to understand the code.

We don't need to look for this on Windows or macOS, and we need to be
able to gracefully handle systems without pkg-config.

systemd can pass in sockets as file descriptors 3 and beyond. Allows
the server to use socket activation.
When triggered by systemd, no other listening sockets (e.g. rfbport) will
be activated.

When the connection is severed, release all mouse buttons.
This fixes an issue with x0vncserver where the local display
would stop responding to mouse events if the connection closes
while the remote user was holding down a mouse button.
To reproduce, start a VNC client, press and hold a mouse button
and then kill the connection (e.g. close client, kill server,
yank network cable). This caused the local screen to no longer
respond to any mouse-down events until a VNC client reconnects
and clicks anywhere.
This may inject a "mouse release" event while closing, however,
if you click on your screen and then yank the mouse cable, a mouse
release event also would not come unexpectedly, so the cure's
side effects aren't as bad as the disease.

This affects the ordering of visuals, which breaks some buggy
applications that assume the first visual is the root window visual.

Use dup() instead to get an available file descriptor to avoid hijacking
already existing descriptor.

Option is -D, which is what sshd uses for the same option.
Also add description of the new option to the vncsession
man page.
Tested on Void Linux using the new option, also tested on
Fedora without using the new option.

It's a reoccurring issue that users try to build individual components
by pointing cmake at a specific subdirectory, e.g. 'cmake vncviewer'.
CMake, unfortunately, has insufficient protection against this so we'll
need to add a manual check.
This commit only adds it to the most likely places for misuse so we
don't have to pollute every CMakeLists.txt.

This is a manually set up table specific for TigerVNC. For clarity,
separate it out from the general keysym/Unicode table.

This is mainly a copy of XKeysymToString() from libX11. We've also added
a wrapper that still gives a string, even if there is no name for the
requested keysym.
This grows the binaries a bit, but not with any extreme amount so is
hopefully worth it to get better debug logging.

Most compilers currently accept arbitrary identifiers in this place
and ignore then, but this is going to change and turn into an error.
(It prevents compilers from diagnosing misspelled type names,
and the resulting declaration is not a prototype, so no type
errors will be reported at call sites.)

This change makes the ZRLEEncoder respect a client's desired
compressionLevel. The ZlibLevel option is marked deprecated and removed
from the manpages.
