This allows to avoid the codes table; furthermore, given
that the runs fit into seven bits and level into nine,
one can put them into one int16_t and use as symbols table
in ff_vlc_init_from_lengths().

Initialize a list of 128 pointers at decoder init
instead of using a const list of pointers (which
will be initialized at runtime when libavcodec
is loaded when using pic code with Elf); the former
takes only 128 bytes (+ a bit of initialization code),
the latter 1KiB on 64 bit systems (+3KiB on x64 elf
for relocation information).

This table is so small (32 elements amounting to 128 bytes)
that it is more efficient size-wise to hardcode it instead
of initializing it at runtime.
Also stop duplicating it in hq_hqa.o and hqx.o.

It is only used by hq_hqa.c, so said header can simply
be included there.
Also move the code to initialize the VLCs to hq_hqa.c.
