fd41cb8491 Fixed rate histogram calculation 
Using small values for --buf-sz= in command line causes
floating point exception due to division by zero.

4e82f01547 Tokenize MB optimized 
Optimized C-code of the following functions:
 - vp8_tokenize_mb
 - tokenize1st_order_b
 - tokenize2nd_order_b
Gives ~1-5% speed-up for RT encoding on Cortex-A8/A9
depending on encoding parameters.

b73a3693e5 Disable __longjmp_chk protection 
glibc implements some checking on longjmp() calls by replacing it with
an internal function __longjmp_chk(), when FORTIFY_SOURCE is defined.
This can be problematic when compiling the library under one version of
glibc and running it under another. Work around this issue for the one
symbol affected for now, before taking out the undef hammer.

Fixes http://code.google.com/p/webm/issues/detail?id=166

0e9a6ed72a Add improvements made in good-quality mode to real-time mode 
Several improvements we made in good-quality mode can be added
into real-time mode to speed up encoding in speed 1, 2, and 3
with small quality loss. Tests using tulip clip showed:

e9751d4b74 Better allocate yuv buffers. 
Previously allocated more memory than necessary for yuv buffers.
This makes it harder to track bugs with reading uninitialized
data.

precision to avoid error caused by right shifting operation.

622958449b New loop filter interface 
Separate simple filter with reduced no. of parameters.
MB filter level picking based on precalculated table. Level table updated for
each frame. Inside and edge limits precalculated and updated just when
sharpness changes. HEV threshhold is constant.
ARM targets use scalars and others vectors.

Change works only with --target=generic-gnu
All other targets have to be updated!

b748045470 Bug fix in motion vector limit calculation 
Motion vector limits are calculated using right shifts, which
could give wrong results for negative numbers. James Berry's
test on one clip showed encoder produced some artifacts. This
change fixed that.
