2e418f5ed8 Make avcodec_thread_init() set the thread count, even in the case when 
threads support is not enabled. This should avoid the need for
thread_count explicit setting in applications.

b750fb6945 Display dimensions should not affect the real size of coded frame, thus set 
only avctx->{width,height} and don't touch coded_{width,height} when parsing
them. This fixes the case when coded and display dimensions differ by more
than one macroblock.

97f9214342 Support reading packed YUV422 10bit samples from Sveriges Television AB (SVT) 
which have AFAIK been created for the jvt:
ftp://vqeg.its.bldrdoc.gov/HDTV/SVT_exports/SVT_YUV10_Exports_/NewMobCal_YUV10_720p5994_/
I have called the format v210x due to its similarity to v210, note though I have
not confirmed that v210x is different from actual v210 samples it just is
different from the description of v210 I am aware of.

420df93037 mlpdec: Don't overallocate buffers. 
Now that max channels and primitive matrices are properly validated, there is
no need to be paranoid that random data will be overwritten.
As a bonus this makes matrix_coeff 16-byte aligned between matrices.
