examples: add a am7xxx-play example program
am7xxx-play is a simple player based on ffmpeg/libav which displays the
output on a am7xxx device. It can be used to capture the desktop screen,
or video from a v4l2 device, or from any other device supported by
libavdevice including video files.
However it is to note that am7xxx-play displays the output as fast as it
can so it is not reliable when used to display video files directly.

cmake: fix libusb search
Adjust cmake test for libusb library so that the compatible libusb for
freebsd can be found. Since freebsd's libusb header are located in
a different place from libusb-1.0, the includes in the source code must
be adjusted using #include <libusb.h>. Actually those new include
statements are those that libusb-1.0 really expects to be used (see
libusb-1.0.pc cflags to verify this).

Serialize struct am7xxx_header properly before sending it on the wire

2. be more portable: this way the buffer sent to the wire is
independent of struct alignments or paddings introduced by
compilers or required by a particular architecture.
