f310c50286 Initialize the last byte of the dictionary to zero so that
lz_get_byte(lz, 0) returns zero. This was broken by
1a3b218598.

596fa1fac7 Always initialize lz->temp_size in lz_decoder.c. temp_size did
get initialized as a side-effect after allocating a new decoder,
but not when the decoder was reused.

1a3b218598 Don't memzero() the history buffer when initializing LZ
decoder. There's no danger of information leak here, so
it isn't required. Doing memzero() takes a lot of time
with large dictionaries, which could make it easier to
construct DoS attack to consume too much CPU time.

ab5feaf1fc Fix LZMA_SYNC_FLUSH handling in LZ and LZMA encoders.
That code is now almost completely in LZ coder, where
it can be shared with other LZ77-based algorithms in
future.

e22b37968d Major changes to LZ encoder, LZMA encoder, and range encoder.
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.

9547e734a0 Don't use coder->lz.stream_end_was_reached in assertions
in match_c.h.

f73c2ab607 Eliminate lzma_lz_encoder.must_move_pos. It's needed
only in one place which isn't performance criticial.
