2008-06-01	Fix a buffer overflow in the LZMA encoder. It was due to my	Lasse Collin	1	-16/+2
	misunderstanding of the code. There's no tiny fix for this problem, so I also cleaned up the code in general. This reduces the speed of the encoder 2-5 % in the fastest compression mode ("lzma -1"). High compression modes should have no noticeable performance difference. This commit breaks things (especially LZMA_SYNC_FLUSH) but I will fix them once the new format and LZMA2 has been roughly implemented. Plain LZMA won't support LZMA_SYNC_FLUSH at all and won't be supported in the new .lzma format. This may change still but this is what it looks like now. Support for known uncompressed size (that is, LZMA or LZMA2 without EOPM) is likely to go away. This means there will be API changes.
2008-04-24	Fix wrong return type (uint32_t -> bool).	Lasse Collin	1	-1/+1

2008-04-24	Fix data corruption in LZ encoder with LZMA_SYNC_FLUSH.	Lasse Collin	1	-0/+4

2008-01-18	Fix LZMA_SYNC_FLUSH handling in LZ and LZMA encoders.	Lasse Collin	1	-0/+1
	That code is now almost completely in LZ coder, where it can be shared with other LZ77-based algorithms in future.
2008-01-14	Major changes to LZ encoder, LZMA encoder, and range encoder.	Lasse Collin	1	-5/+12
	These changes implement support for LZMA_SYNC_FLUSH in LZMA encoder, and move the temporary buffer needed by range encoder from lzma_range_encoder structure to lzma_lz_encoder.
2008-01-10	Eliminate lzma_lz_encoder.must_move_pos. It's needed	Lasse Collin	1	-4/+0
	only in one place which isn't performance criticial.
2007-12-09	Imported to git.	Lasse Collin	1	-0/+161
