am7xxx: rename am7xxx_header.unknown0 to am7xxx_header.direction
This field should indicate the direction of the communication, according to
the USB dumps it is 0 for outgoing packets and 1 for incoming packets.

am7xxx-play: check if strtok_r is available
On Windows systems, where strtok_r is not available, strtok_s could be
used but this needs the C Run-Time library (msvcrt.dll or msvcr80.dll)
and we can't distribute it.
So for now, when strtok_r is not available, just print a message to warn
the user that the '-o' options is not available.

am7xxx-play: get the framerate from the video stream
When setting the output codec get the time_base (which indicates the
framerate) from the video stream, not from the input codec context, this
is the correct way to do it.
On some systems (Windows) the time_base from the input codec context is
set different from the one of the video stream, and timebase.num ends up
being 0 which results in the output codec initialization failing with
the message "framerate not set".

mingw_cross_toolchain.cmake: set the MINGW variable to True
Setting MINGW to True is important to let cmake set some variables such
as CMAKE_FIND_LIBRARY_PREFIXES and CMAKE_FIND_LIBRARY_SUFFIXES from
Platform/Windows-GNU.cmake
I wasted a lot of time on this with find_library() not finding libav
libraries compiled for MingW whith the ".dll.a" suffix.
