More cleaning for libwmapro; use codeclib's bitstream functions and drop those from the libwmapro.

-name
-    arbitrary name which is used as prefix for the internal variables
-
-gb
-    getbitcontext
-
-OPEN_READER(name, gb)
-    loads gb into local variables
-
-CLOSE_READER(name, gb)
-    stores local vars in gb
-
-UPDATE_CACHE(name, gb)
-    refills the internal cache from the bitstream
-    after this call at least MIN_CACHE_BITS will be available,
-
-GET_CACHE(name, gb)
-    will output the contents of the internal cache, next bit is MSB of 32 or 64 bit (FIXME 64bit)
-
-SHOW_UBITS(name, gb, num)
-    will return the next num bits
-
-SHOW_SBITS(name, gb, num)
-    will return the next num bits and do sign extension
-
-SKIP_BITS(name, gb, num)
-    will skip over the next num bits
-    note, this is equivalent to SKIP_CACHE; SKIP_COUNTER
-
-SKIP_CACHE(name, gb, num)
-    will remove the next num bits from the cache (note SKIP_COUNTER MUST be called before UPDATE_CACHE / CLOSE_READER)
-
-SKIP_COUNTER(name, gb, num)
-    will increment the internal bit counter (see SKIP_CACHE & SKIP_BITS)
-
-LAST_SKIP_CACHE(name, gb, num)
-    will remove the next num bits from the cache if it is needed for UPDATE_CACHE otherwise it will do nothing
-
-LAST_SKIP_BITS(name, gb, num)
-    is equivalent to LAST_SKIP_CACHE; SKIP_COUNTER
