9cd8179818 #defines for strict_std_compliance and split between inofficial extensions and non standarized things

132041f06f While adding stereo rematrixing, I came across something that needs to 
be fixed even without adding the feature.  The output correctly uses 4
dummy values for the rematrixing flags in block-0, but the bit
allocation routine does not take these bits into account.  From what I
can tell, there was a patch in 2003 that corrected the output to make it
DVD and spec compatible, but it didn't correct the bit allocation.  It's
only 4 bits over the entire 6 blocks, so overflow errors would happen
rarely or never, but it's still worth fixing.  So here is a fix.

b44985ba12 store the number of runs to avoid storing the last run value 
about 10% lower bitrate for -qscale 32 (forman & some music video)
worst case bitrate increase <0.1% (lossless or low qscale)
and now the bad news, even though this just adds a single subtraction and an if() into the medium sized unpack_coeffs() loop and the if() will only be false once per unpac_coeff() call, gcc produces 50% slower code, i didnt look at the generated asm yet, not sure if i want to ...

a0a74ad9f0 increasing precission of the quantization parameter 
this is needed as the quantization stepsize for each subband is also in this precission and insignificant changes to the wavelet like scaling its coefficients slightly differently would lead to wildly variing PSNR and bitrate
note, a encoder could also simply choose to leave the least significant bits of the quantization parameters zero which would give the exact previous behaviour except a y very tiny number of bits in  the header

ccff9da62a H261 fixing and cleaning: 
-corrected wrong value in mv data
 -set correct mb_type after adjusting index
 -don't use H263 loop filter when the loop filter flag is set but when
  using the H261 encoder
 -use the same unquantizer as H263 (which is optimized btw)
 -removed unused members in H261Context
