This fixes a number of unused-but-set gcc warnings.

Istvan Sebok provided a sample where field pair -> two fields content
was being misdetected by the existing logic. I added an additional
test to check the input picture type as identified by our h.264
parser.

The function is not implemented (and possibly useless).

The scale filter is used for internal colorspace conversions, so it must
always be present.

Implement av_buffersrc_get_nb_failed_requests.
Deprecate av_vsrc_buffer_get_nb_failed_requests.

It is no longer used anywhere.

Furthermore, the header it was declared in was not installed,
so it can not be considered part of the public API.

av_buffersrc_add_ref can handle audio too now.

The strtol() interface makes it difficult to use with
const-qualified pointers.  With this change, although
the const is still lost, the compiler does not warn
about it.
