2a5ac99e6e x11grab: Check the XQueryPointer return value
The paint_mouse_pointer() code uses XFixes to retrieve the cursor
coordinates, but XFixes gives no information about which screen the
pointer is on; this results in always drawing the cursor on the
captured screen even if the mouse pointer was on another screen.

For example, when capturing from screen 1 (i.e. -f x11grab -i ":0.1")
the cursor was being drawn in the captured image even when the mouse
pointer was actually on screen 0, which is wrong and visually confusing.

69c34a6ac9 avdevice/x11grab: fix cursor drawing in multi-screen setup
The code uses XFixes to retrieve the cursor coordinates, but XFixes
gives no information of what screen the pointer is on; this results in
always drawing the cursor on the captured screen even if the mouse
pointer was on another screen.

For example, when capturing from screen 1 (i.e. -f x11grab -i ":0.1")
the cursor was being drawn in the captured image even when the mouse
pointer was actually on screen 0, which is wrong and visually confusing.

Use XQueryPointer to check that the pointer is actually on the screen
which is being captured.

preparation of a subsequent change which will introduce a temporary
Window variable for which "w" is an good name.

d3958ab4ed x11grab: fix a memory leak exposed by valgrind
When using "-f x11grab -i :0.0" valgrind reports a definitely lost
memory block with this message:

==31544== 5 bytes in 1 blocks are definitely lost in loss record 1 of 2
==31544==    at 0x4026E68: memalign (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==31544==    by 0x4026F17: posix_memalign (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==31544==    by 0x60D399A: av_malloc (in /usr/lib/x86_64-linux-gnu/libavutil.so.51.22.1)
==31544==    by 0x60D3A70: av_strdup (in /usr/lib/x86_64-linux-gnu/libavutil.so.51.22.1)
==31544==    by 0x4A2BE58: ??? (in /usr/lib/x86_64-linux-gnu/libavdevice.so.53.2.0)
==31544==    by 0x506D29E: avformat_open_input (in /usr/lib/x86_64-linux-gnu/libavformat.so.53.21.0)
==31544==    by 0x400A80: main (in /home/ao2/WIP/am7xxx-play/tests/a.out)

The 5 bytes lost are the ones from param = av_strdup(":0.0"), so let's
free param in the exit path.

Also check the av_strdup() return value.

Note: calling av_free(param) even when av_strdup() fails and param is
NULL is OK and keeps the code simpler without adding another label to
skip av_free().
