Enable building libav without optimization

Browse Source 
Some source files do not build with -O0 due to conflicting register
allocation and inline assembler constrains. We enforce optimization (O2)
for these files.

Also, I reduced the noise from warning messages induced by lazy handling
of "assignment discards ‘const’ qualifier" and "passing argument from
incompatible pointer type" in third-party sources.
