bytestream2: set the reader to the end when reading more than available
Merged-by: Michael Niedermayer <michael@niedermayer.cc>
This also prevents an eventual compilation failure once request_channels
is removed.

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.
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.

This makes the output compatible with that of pretty much any other
tool that calculates PSNR.
