postproc: Made QP, nonBQP, and pQPb arrays
...
Also pulled QP initialization out of inner loop, which removed some redundent code.
Added some dummy fields to PPContext to allow current code to work while
changing the rest of the postprocessing code to support the arrays.
I also increased alignment requirements for some fields in the PPContext struct to
support future avx2 code.

postproc: Replaced inline asm for prefetching with prefetch functions
...
Prefetching functions are defined in postprocess_template using the
RENAME macro so that prefetching is used when available. For x86
targets inline asm is used and the functions are non-empty only for
cpus where prefetching is available. For non x86 targets the gcc bultin
prefetch is used if it is available, otherwise no prefetching is done.

postproc: Removed unecessary if/else branch when getting QP.
...
There's still an if, as QP needs to be modified if isColor=0, but it
still removes a unecessary branch.

* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.
