2257f66ec5 lavc: drop libdirac encoder. 
Libschroedinger is the preferred way to encode dirac video now, it
produces better output and has a nicer API.

01cb62aba2 lcl: don't overwrite input memory. 
If the PNG filter is enabled, a PNG-style filter will run over the
input buffer, writing into the buffer. Therefore, if no zlib compression
was used, ensure that we copy into a temporary buffer, otherwise we
overwrite user-provided input data.

b5696ff2b8 prores: use natural integer type for the codebook index 
The operations that use it require it to be promoted to a larger (natural)
type and thus perform sign extension on it.

While an optimal compiler may account for this, gcc 4.6 (for x86 Windows)
fails. Using the natural integer type provides a 2% speedup for Win64
and 1% for Win32.

3ab9a2a557 rv34: change most "int stride" into "ptrdiff_t stride". 
This prevents having to sign-extend on 64-bit systems with 32-bit ints,
such as x86-64. Also fixes crashes on systems where we don't do it and
arguments are not in registers, such as Win64 for all weight functions.

After:
