982da7ed31 The .xz file format specification version 1.0.0 is now
officially released. The format has been technically the same
since 2008-11-19, but now that it is frozen, people can start
using it without a fear that the format will break.

3241317093 Fix uninitialized variables in alone_decoder.c. This bug was
triggered by the previous commit, since these variables were
not used by anything before support for a preset dictionary.

f76e39cf93 Added initial support for preset dictionary for raw LZMA1
and LZMA2. It is not supported by the .xz format or the xz
command line tool yet.

128586213f Beta was supposed to be API stable but I had forgot to rename
lzma_memlimit_encoder and lzma_memlimit_decoder to
lzma_raw_encoder_memlimit and lzma_raw_decoder_memlimit. :-(
Now it is fixed. Hopefully it doesn't cause too much trouble
to those who already thought API is stable.

dc8f3be06d Fixed a bug in 7z2lzma.bash to make it work with .7z files
that use something else than 2^n as the dictionary size.
Thanks to Dan Shechter for the bug report.

322ecf93c9 Renamed lzma_options_simple to lzma_options_bcj in the API.
The internal implementation is still using the name "simple".
It may need some cleanups, so I look at it later.

7ed9d943b3 Remove lzma_init() and other init functions from liblzma API.
Half of developers were already forgetting to use these
functions, which could have caused total breakage in some future
liblzma version or even now if --enable-small was used. Now
liblzma uses pthread_once() to do the initializations unless
it has been built with --disable-threads which make these
initializations thread-unsafe.

When --enable-small isn't used, liblzma currently gets needlessly
linked against libpthread (on systems that have it). While it is
stupid for now, liblzma will need threads in future anyway, so
this stupidity will be temporary only.

When --enable-small is used, different code CRC32 and CRC64 is
now used than without --enable-small. This made the resulting
binary slightly smaller, but the main reason was to clean it up
and to handle the lack of lzma_init_check().

The pkg-config file lzma.pc was renamed to liblzma.pc. I'm not
sure if it works correctly and portably for static linking
(Libs.private includes -pthread or other operating system
specific flags). Hopefully someone complains if it is bad.

lzma_rc_prices[] is now included as a precomputed array even
with --enable-small. It's just 128 bytes now that it uses uint8_t
instead of uint32_t. Smaller array seemed to be at least as fast
as the more bloated uint32_t array on x86; hopefully it's not bad
on other architectures.

050eb14d29 Revert a change made in 3b34851de1
that was related to LZMA_MODE_FAST. The original code is slightly
faster although it compresses slightly worse. But since it is fast
mode, it is better to select the faster version.

e33194e79d Bunch of liblzma tweaks, including some API changes.
The API and ABI should now be very close to stable,
although the code behind it isn't yet.

634636fa56 Remove the alignment functions for now. Maybe they will
be added back in some form later, but the current version
wasn't modular, so it would need fixing anyway.

a94bf00d0a Some adjustments to GCC warning flags. The important change
is the removal of -pedantic. It messes up -Werror (which I
really want to keep so that I don't miss any warnings) with
printf format strings that are in POSIX but not in C99.
