When receiving bogus data, we have to avoid subtracting a value
larger than 'size' from 'size' variable, resulting in a wrap
that would make 'size' a really large bogus value.

This removes a good 50% of processing time for parsing a buffer.
We do this by simply... getting the nicks that we already have handy
instead of going through the expensive glib system.
Remove the gst-plugins-ugly-plugins.args.new and
gst-plugins-ugly-plugins.signals.new files, that appear
to have been accidentally added in commit

Previously, we could get false sync relatively easily - it sometimes happened
on real files. This cleans the code up a fair bit, and makes it require more
confirmation that we've found valid sync before continuing.
liba52 in a52dec-0.7.4 does not have any MMX, MMXEXT or 3DNOW based
IMDCT transform acceleration. It does however have a software based
acceleration using the djbfft library (D.J. Bernstein's library for
fourier transforms - Extremely fast library for floating-point
convolution). So allow liba52 to use it through the MM_ACCEL_DJBFFT
flag.
The liba52 copy in MPlayer sources does have SSE, 3dnowext, 3dnow
and AltiVec implementations, but those are checked for first, and
djbfft is chosen only if none of those is available - good in the
case of some distributions including a port of the MPlayer changes
in their system a52dec library.
The down and upmix code in liba52 doesn't seem to be disturbed by
this additional MM_ACCEL flag and will still use MMX, SSE or 3DNOW
versions if passed from oil_cpu_get_flags (SSE currently is not).
Fixes bug #592787.
Metadata provided seek tables are consistent with metadata's view of
total size, which typically matches real size, but need not do so
(e.g. a truncated file). Fixes seeking and position reporting
in such truncated files (although duration based on metadata may then
still be incorrect).
asf packets in rtp packets should come with their padding fields
set to 0 and the depayload must update them to the correct
value before pushing downstream
