libbb: split bb_get_chunk_from_file and bb_get_chunk_with_continuation
This also moves bb_get_chunk_with_continuation into its sole user, parse_config.c. This allows to optimize both functions separately, they need to be optimized for speed. (this need was highlighted by slow modprobe caused in part by slow bb_get_chunk_with_continuation in config parser). function old new delta bb_get_chunk_from_file 7 130 +123 config_read 457 558 +101 bb_get_chunk_with_continuation 194 - -194 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 2/0 up/down: 224/-194) Total: 30 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
