/* Bitstream reader API docs:
454
abritary name which is used as prefix for the internal variables
459
OPEN_READER(name, gb)
460
loads gb into local variables
462
CLOSE_READER(name, gb)
463
stores local vars in gb
465
UPDATE_CACHE(name, gb)
466
refills the internal cache from the bitstream
467
after this call at least MIN_CACHE_BITS will be available,
470
will output the contents of the internal cache, next bit is MSB of 32 or 64 bit (FIXME 64bit)
472
SHOW_UBITS(name, gb, num)
473
will return the nest num bits
475
SHOW_SBITS(name, gb, num)
476
will return the nest num bits and do sign extension
478
SKIP_BITS(name, gb, num)
479
will skip over the next num bits
480
note, this is equinvalent to SKIP_CACHE; SKIP_COUNTER
482
SKIP_CACHE(name, gb, num)
483
will remove the next num bits from the cache (note SKIP_COUNTER MUST be called before UPDATE_CACHE / CLOSE_READER)
485
SKIP_COUNTER(name, gb, num)
486
will increment the internal bit counter (see SKIP_CACHE & SKIP_BITS)
488
LAST_SKIP_CACHE(name, gb, num)
489
will remove the next num bits from the cache if it is needed for UPDATE_CACHE otherwise it will do nothing
491
LAST_SKIP_BITS(name, gb, num)
492
is equinvalent to SKIP_LAST_CACHE; SKIP_COUNTER
