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.

079c4f7fc2 Don't add -g to CFLAGS when --enable-debug is specified. 
It's the job of the user to put that in CFLAGS.

61d1784d8f Set stdin and stdout to binary mode on Windows. This patch is 
a forward port of b7b22fcb979a16d3a47c8001f058c9f7d4416068
from lzma-utils-legacy.git. I don't know if the new code base
builds on Windows, but this is a start.

c9cba97691 Added test_compress.sh and bunch of files needed by it. 
This new set of tests compress and decompress several
test files with many different compression options.
This set of tests will be extended later.

33be3c0e24 Subblock decoder: Don't exit the main loop in decode_buffer() 
too early if we hit End of Input while decoding a Subblock of
type Repeating Data. To keep the loop termination condition
elegant, the order of enumerations in coder->sequence were
changed.

To keep the case-labels in roughly the same order as the
enumerations in coder->sequence, large chunks of code was
moved around. This made the diff big and ugly compared to
the amount of the actual changes made.

b254bd97b1 Fix wrong too small size of argument unfiltered_max 
in ia64_coder_init(). It triggered assert() in
simple_coder.c, and could have caused a buffer overflow.

This error was probably a copypaste mistake, since most
of the simple filters use unfiltered_max = 4.

f88590e001 Fix Subblock docoder: If Subblock filter was used with known 
Uncompressed Size, and the last output byte was from RLE,
the code didn't stop decoding as it should have done.

01d71d60b7 Free the allocated memory in lzmadec if debugging is

f10fc6a69d Use fastpos.h when encoding LZMA dictionary size in 
Filter Flags encoder.

e5728142a2 Revised the fastpos code. It now uses the slightly faster 
table-based version from LZMA SDK 4.57. This should be
fast on most systems.

A simpler and smaller alternative version is also provided.
On some CPUs this can be even a little faster than the
default table-based version (see comments in fastpos.h),
but on most systems the table-based code is faster.

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.

Lasse Collin
3e09e1c058 In lzma_read_match_distances(), don't use 
coder->lz.stream_end_was_reached. That variable
will be removed, and the check isn't required anyway.
Rearrange the check so that it doesn't make one to
think that there could be an integer overflow.

382808514a Define HAVE_ASM_X86 when x86 assembler optimizations are

c7189d981a Test for $GCC = yes instead of if it is non-empty. This 
way it is possible to use ac_cv_c_compiler_gnu=no to
force configure to think it is using non-GNU C compiler.
