Particularly those that will be needed by the QSV decoder.
More can be added later as necessary.

That loop does the actual full decoding, so 'parse' can be misleading.

This function is independent of the decoding context, so we'll be able
to use it in the parser.

Also, make hls_nal_unit() work only on the provided NAL unit, without
requiring a whole decoding context.

This will allow splitting this code for reuse by the parser.

There is no need to wait until actually decoding the NALU. This will
allow to get rid of the second hls_nal_unit() call later.

Factor out the parameter sets into a separate struct and use it instead.

This will allow us to reuse this code in the parser.

It is used as get_bits argument and reading 0 bits doesn't make sense.

This prevents possible infinite loops with the calling code along the
lines of while (bytestream2_get_bytes_left()) { ... }, where the reader
does not advance.

It provides the following features:
 * verify correctness by comparing output to the C version.
 * detect failure to save and restore clobbered callee-saved registers.
 * detect 32-bit parameters being used as if they were 64-bit in x86-64
   (the upper halves are not guaranteed to be zero - but in practice
   they very often are, which makes those bugs hard to spot otherwise).
 * easy benchmarking.

Compile by running 'make checkasm'.
Execute by running 'tests/checkasm/checkasm'.

Optional arguments are '--bench' to run benchmarks for all functions,
'--bench=<pattern>' to run benchmarks for all functions that starts with
<pattern>, and '<integer>' to seed the PRNG for reproducible results.

Contains unit tests for most h264pred functions to get started, more tests
can be added afterwards using those as a reference.

Loosely based on code from x264. Currently only supports x86 and x86-64,
but additional architectures shouldn't be too much of an obstacle to add.

Note that functions with floating point parameters or floating point
return values are not supported. Some compiler-specific features or
preprocessor hacks would likely be required to add support for that.
