2013-04-12xzcat: more cleanup and some shrinking.Isaac Dunham
-drop __always_inline (c. 1.5k of binary size), -remove the xz_dec_bcj_end and memzero macros (memeq is left because of negative returns), -disable XZ_DEC_SINGLE and XZ_DEC_PREALLOC, since we aren't using them. (160 bytes) -Merge xz_dec_lzma2_end into xz_dec_end -Move xz_crc32 to where it's defined. (That does not seem to be duplicated elsewhere in toybox.)

2013-04-11More of same.Isaac Dunham
Actually, it's not quite the same: -use crc_init(xz_crc32_table,1) -- I guessed on this one based on a match between magic constants, then tested it. First try was wrong, but this works. (This is the sole difference in terms of actual _code_, as opposed to cleaning up defines and the like--here, it adds 48 bytes to final size if xzcat is the only toy, but drops 32 bytes if bzcat is also enabled...) -Move some crc64 code to where the comments are. This puts them near the area where they're used. -Remove some relics of separate files (we had half a dozen "this file is in the public domain" notices, a duplicate include, and used extern declarations for functions in the samefile)

glued all his files together into one big one and threw it in pending. It needs something between cleanup and a complete rewrite.
