Add patches for block-level quant in theora, -O2 on build, and statically
link pthread on Windows
For Theora changes, also includes 4 patches that fix various decoder crash
bugs in theora due to bad clamping of values, or forgetting to check return
codes.
There is a build settings patch to use -O2 for all platforms instead of
-O3, and to statically link pthreads on windows. This reduces the produced
binary sizes, and decreases CPU usage by like 10% on windows.
