Måns Rullgård b7fa5c5abb random_seed: allow to block on /dev/random
If both /dev/random and /dev/urandom failed to return data, an
uninitialised value might be returned.  Since most systems have a
non-blocking /dev/urandom or have /dev/random with similar properties,
the chance of blocking is minimal, and the alternative of returning
non-random data is worse.

Jason Garrett-Glaser 4148855ee4 Eliminate another redundant instruction in vp56/8 arithcoder
Necessary because of this GCC bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44474
To do this, convert some, but not all (!) of the variables in VP56RangeCoder
into local variables.
If we convert c->high into a local variable, gcc gets the stupids and refuses
to use a conditional move for the unpredictable main branch.

TODO: dispense with this bullshit and write an asm version.

Jason Garrett-Glaser 36d6b545a1 CMOV-ify vp56 arithcoder
This incantation causes gcc 4.3 to generate cmov on x86, a vastly better option
than a completely unpredictable branch.
Hopefully this carries over to newer versions and other CPUs with conditionals.
~5 cycles saved per call on a Core i7.

Makes it give correct results with e.g. gcc 4.4.

on e.g. gcc 4.3, making the code a bit larger but also
