The patch will change the numerical values for the string constants so bump
micro version.

This patch adds a select_region option to the xcbgrab input device.
If set to 1, the user will be prompted to select the grabbing area
graphically by clicking and dragging. A rectangle will be drawn to
mark the grabbing area. A single click with no dragging will select
the whole screen. The option overwrites the video_size, grab_x, and
grab_y options if set by the user.
For testing, just set the select_region option as follows:
ffmpeg -f x11grab -select_region 1 -i :0.0 output.mp4
The drawing happens directly on the root window using standard rubber
banding techniques, so it is very efficient and doesn't depend on any
X extensions or compositors.

Apparently bmdFormatUnspecified needs SDK 11.0. It is just a fancy way of
checking for zero, so let's do that instead.

Since bae8844e35, the AVPacket that is
intended to be used to return the demuxed packet is automatically
unreferenced when the demuxer returns an error. This makes an
av_packet_unref() in the lavfi demuxer redundant.

av_new_packet() already sets the size. And if the packet is not
allocated by av_new_packet() (which seems to be impossible atm), both
pkt->size as well as size are 0, so setting it again is unnecessary in
this scenario, too.

Fixes#7312, segmentation fault on close of X11 server
xcb_query_pointer_reply() and xcb_get_geometry_reply() can return NULL
if e.g. the X server closes or the connection is lost. This needs to
be checked in order to cleanly exit, because the returned pointers are
dereferenced later.

X2RGB10 tested on both Intel Gen9 and AMD Polaris 11. NV12 tested on
Intel Gen9 only - since it has multiple planes, this requires GetFB2.
Also add some comments to split the list up a bit.
The most useful feature here is the ability to automatically extract the
framebuffer format and modifiers. It also makes support for multi-plane
framebuffers possible, though none are added to the format table in this
patch.
This requires libdrm 2.4.101 (from April 2020) to build, so it includes a
configure check to allow compatibility with existing distributions. Even
with libdrm support, it still won't do anything at runtime if you are
running Linux < 5.7 (before June 2020).
Apparently the changes from 3c9185bf3a
aren't enough; even with that in place, I got errors like this
when trying to build for iOS:
src/libavdevice/avfoundation.m:135:5: error:
'AVCaptureDeviceTransportControlsPlaybackMode' is unavailable: not
available on iOS
AVCaptureDeviceTransportControlsPlaybackMode observed_mode;
^
The capture_started variable was never set, it is simpler to call the stop
functions unconditionally if the interface is available.

Also by wrapping the SHM buffer in an AVBufferRef we eliminate yet another
possible memcpy improving performance.
