6e7ef5ec35 Probetest, to test the demuxers probe functions against random and not so random
input.

97e078087b Improve sierravmd probe. It is still quite weak, but further improvements
are non-obvious and probably need a large (about 1kB at least) probe buffer.

6377de611a Try harder to avoid false positives for DV probe.
Require at least one signature match per provided 1MB of probe data,
and if there is only a single match, return at most MAX/4.
Fixes issue1382 but could/should probably still be improved.

98487a5b69 Make dnxhd probe more strict, fail if we detect values in header that would
make our decoder fail anyway.
dnxhd probe now passes probetest.

89c4e176f6 Rewrite h261_probe().
New code can detect h261 startcodes even when the first is damaged or not at the
begin. It also passes probetest v2 & v3.

05bdd33a12 Make DTS probe more robust against false positives (as e.g. probetest shows).
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.

9f449d57c7 Check the index validity more thoroughly for the c93 probe function.
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.

ddbb7c9be2 Add more sanity checks for header elements, rejecting files with clearly
invalid values that wouldn't play right anyway and reduce probe score to MAX/2.

e4c01d408a Rewrite h263_probe().
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.

8466ab59b2 Check buffer size for idcin check, otherwise false positives are too likely for
small probe buffer sizes due to 0-padding (see probetest results).

cbb5da57cd When resetting vst->pkt.data to NULL, also set vst->slices.
This avoids a crash when the next slice is not a start slice and thus
pkt->data is still NULL.
This probably only happens with broken or unsupported files like
http://samples.mplayerhq.hu/real/multirate/JustaSpa1937_64kb.rm
that need further fixes, but keeping vst state consistent is still a good idea.

46c32e2654 Prepare for optimised forward MDCT implementations
This adds a function pointer for forward MDCT to FFTContext and
initialises it with the existing C function.  ff_calc_mdct() is
changed to an inline function calling the selected version as
done for other fft/mdct functions.
