In some conditions, where the first band was being zeroed mainly, the wrong global gain scalefactor would be written to the stream since it's always taken from the first band regardless of whether it's been marked as zero or not. So, always make sure it contians something useful.

When both M/S coding and PNS are enabled, scalefactors and coding books would be mistakenly clobbered when setting the M/S flag on PNS'd bands. The flag needs to be set to signal the generation of correlated noise, but the scalefactors, coefficients and the coding books need to be kept intact.

Commit 14ea4151 had a bug in that the conversion of the uint64_t result to an int (the return signature) would lead to implementation defined behavior, and in this case simply returned 0 for NAN. A fix via AND'ing the result with 1 does the trick, simply by ensuring a 0 or 1 return value. Patch tested with FATE on x86-64, GNU/Linux by forcing the compatibility code via an ifdef hack suggested by Michael. Signed-off-by: NGanesh Ajjanagadde <gajjanagadde@gmail.com>

lrintf is anyway used, suggesting we only care up to floating precision. Rurthermore, there is a compat hack in avutil/libm for this function, and it is used in avcodec/aacps_tablegen.h. This yields a non-negligible speedup.

This rewrites into a similar expression avoiding sqrt. Similarity is assured since sqrt(x^2 + y^2)/(x+y) lies in [1/sqrt(2), 1] for x, y > 0. Tested on x86-64, Haswell, GNU/Linux.

avcodec/mpegvideo_enc: Remove slice structured mode from H.263 as well as the code automatically enabing it There is no such thing as a slice structured mode in the original version 1 H.263, that mode was added in H.263+ in 1998. Also the headers for slice structured mode are not part of the older version 1 and this would result in unplayable files An alternative to this patch would be to merge the H263 and H263P AVCodecs and use other means to distinguish the older and newer versions.
