Implements the decoding of video streams using common H264 decoders. We also implement
a trivial feedback algorithm.

Some window managers do not support _NET_WM_FULLSCREEN_MONITORS.
In that case multimonitor fullscreen does not properly work, so
add a path resizing the window over all screens instead.
Based on @erbth pull request, adding proper X11 atom checks.
If the display channel is available we use it to allow the user to resize the
xfreerdp window. When the window is resized we announce a new monitor layout and
the server reacts by doing a reactivation sequence to the new size.
The minimum window size is limited to 300x300 as 2012 servers crash horribly
if we send them a smaller layout.
* client/x11: Fix colors on big endian
The bitmaps are recieved in little endian byte order (LSBFirst in terms
of X11). This is a problem on systems, where bitmaps are expected in big
endian byte order (MSBFirst). X11 client tries to handle this situation
by different color formats (e.g. RGBX vs. BGRX), but this doesn't work.
BGRX is not MSBFirst variant of RGBX, it should be XRGB. But this would
work only for 32/24 depths, where color channels matches bytes. Let's
say to the XServer that all the bitmaps are in LSBFirst encoding instead
of changing the color formats on big endian systems.

* client/x11: Fix cursor color on big endian
The cursor color is wrong on big endian systems. It is not probably
possible to force bitmap_order for XcursorImage as it is possible for
XImage. Fortunately, cursors are always 32 bit so we can use ABGR
instead of BGRA to deal with.

* client/x11: Fix comment indentation
The comment has wrong indentation for some reason, let's fix it.
* client/x11: Fix BGR vs. RGB detection
The BGR vs. RGB detection code is leftover from history and I am conviced
that it is wrong with the current color handling, where invert flag is TRUE
by default. However, I suppose that the detection still makes sense and
XServer may use the inverted formats in some cases. Maybe we can force XServer
to use our masks somehow, but let's just fix the value to FALSE now.
* client/x11: Remove unused color shifts
The color shifts are lefover from history and are not used in current
code. Let's remove them.
RDP expects to receive an indicator of the physical mouse button that
was pressed on the client, whereas X11 deliver a value for which
logical mouse button that was pressed.
This patch introduces a (reverse) mapping from logical mouse buttons to
physical mouse buttons, so that the RDP server can do correct mapping
for the event on its end.
However, no actual mapping is done here; this patch just introduces the
framework to do so. Thus, there should be no behavioural change from
this patch alone.
There is an implicit assumption that only the first three buttons are
mapped to eachother. Enabling more a general mapping would require
extensive changes to the event handling as fourth logical button and
up is used for special functionality such as wheel.
1. Make use of freerdp_set_last_error to set authentication failure without the helper functions
2. Rename ssl callback function
3. Break out AuthenticationOnly exit handling from bad connect handling
When using software gdi (/gdi:sw) the rdp update PDU callback
gdi_palette_update() is used which writes the new colors to
the rdpContext's gdi->palette buffer.
The X11 functions however access xfc->palette which gets only
updated by xf_gdi_palette_update() which is the callback if
/gdi:hw is used.
This commit changes xfc->palette to a pointer which points to
xfc's private buffer with /gdi:hw or to the gdi->palette if
software gdi is used.
- make smart-sizing work again which was killed in previous commits
- removed several unnecessary/ugly workarounds
- miscellaneous small fixes
- new feature: restore previous window position when toggling out of
fullscreen mode
- new feature: if /f is specified in combination with /smart-sizing:WxH
we run the session in the /smart-sizing dimensions scaled to full screen
Since several contributers in the past repeatedly made the error
to treat xfc->width and xfc->height as equal with the x11 window
width and heigth I've renamed these variables to sessionWidth and
sessionHeight.
Small cleanup of passing around decorations flag.
Limit PercentScreen to single monitor vs. entire desktop. IMO - this is better behavior in a multimonitor environment.
Handle fullscreen windows better:
1. Ensure that size hints are set to allow resizing before setting a window to fullscreen as some window managers do not behave properly.
2. Handle fullscreen toggles without destroying and recreating window.
3. Use NET_WM_STATE_FULLSCREEN Extended Window Manager Hint for fullscreen functionality
4. Use the NET_WM_FULLSCREEN_MONITORS Extended Window Manager Hint when appropriate
5. When a single monitor fullscreen is requested - use the current monitor(as determined from mouse location)
6. Handle cases where there is no local monitor at coordinate 0,0. The Windows server expect there to be a monitor at this location, so we maintain offset if necessary between our local primary monitor and the server side primary monitor located at 0,0.
Note: /gdi:sw was working fine, this commit fixes /gdi:hw
* calculate color channel shifts based on X11 visual color masks
* fast path to skip conversion if visual color masks equal rdp color masks
* successfully tested 8/15/16/24/32 bpp rdp sessions on 16/24/32 bpp visuals
* fixed crash on server-initiated desktop resize and fullscreen toggle with /gdi:sw
* implemented desktop resize for /gdi:sw
* check for availibility of XRender extension and show error messages if a setting would require it
* fixed compile error if xrender devel packages are missing
* fixed bug with server-initiated desktop resize in fullscreen mode
