if the "shared" var has not been explicitely enabled, rather than if
it has been explicitly disabled.

This way is not necessary to explicitly disable shared libraries in
order to have a pc file usable with only static libraries.

New code can detect h261 startcodes even when the first is damaged or not at the
begin. It also passes probetest v2 & v3.

In particular check that the detected markers clearly indicate a specific DTS
format (a wild mixture of e.g. little- and big-endian markers is unlikely to be
a valid DTS file) and ensure the markers appear with sufficient frequency.

In particular, check that length of the first index entries is not 0 since
that is interpreted "end of file" and makes no sense in the very first entries.

Passes probetest v2.

Originally committed as revision 19842 to svn://svn.ffmpeg.org/ffmpeg/trunk

The new code should detect h263 even if the first startcode is damaged or
somewhere else than the first byte. It also passes probetest v2 as just
posted on ffmpeg-dev.
