Remove debug code under '#if !defined(NDEBUG)' still using av_clamp_mv().

Parse and use it instead.

This is more in line with the behavior from libaom.

This is identical to what libaom does for such OBUs. It prevents us
from doing block decoding, which doesn't make sense for such OBUs,
and would result in using an uninitialized frame header during the
decoding process. Fixes #94.

Otherwise, if the non-last has a max value, the ones after it can go

For MachO, this makes sure that the label difference actually is
evaluated at assembly time (as it already was for ELF and COFF);
evaluating it at link time failed when the difference is stored in
a .hword.

This fixes linking errors like these:
ld: in section __TEXT,__text reloc 0: ARM64_RELOC_SUBTRACTOR must have r_length of 2 or 3 file 'src/src@@dav1d_bitdepth_8@sta/arm_64_mc.S.o' for architecture arm64

This adds an asm.S macro for decorating a symbol for making a
local symbol. For armasm64 with gas-preprocessor, this doesn't
actually create a local label (but neither do the local numbered
labels either currently), which might be slightly inconsistent
in it would be necessary to make the distinction for that assembler
as well.

Alternatively, the table symbol could be made into a plain local
numbered label as all the other labels.

Replaces the boolean 'build_libfuzzer' meson option with 'fuzzing_engine'.
This allows reproducing fuzzing test cases on systems without libfuzzer.
Also prevents regressions in the fuzzing test target since it will be
build by default.

As indicated in the spec, get_poc_diff should return 0 when
order_hints are disabled.

Closes #77

Calling get_uniform(max=1) results in a read_bits(n=0),
In get_uniform, the n param is renamed to max to clarify the
semantics. Asserts are added to detect calls to get_uniform()
and get_bits() that don't actually read anything.

armasm64 fails to assemble this:
error A2173: syntax error in expression
        sub             x7,  x7,  w4, uxth

This clearly is a bug in armasm64, and will be reported. For now,
this workaround should be harmless though, as we've just loaded
the register with ldrh, so the upper parts of the register should
be zeroed.

Fixes #60.

These can be used in intrabc coding. Fixes #74.
