0e27028d74 Add a separate internal function to initialize the CRC32 
table, which is used also by LZ encoder. This was needed
because calling lzma_crc32() and ignoring the result is
a no-op due to lzma_attr_pure.

880c330938 Make it easy to choose if command line tools should be 
linked statically or dynamically against liblzma. The
default is still to use static liblzma, but it can now
be changed by passing --enable-dynamic to configure.
Thanks to Mike Frysinger for the original patch.

Fixed a few minor bugs in configure.ac.

3306cf3883 Introduced LZMA_API_STATIC macro, which the applications 
need to #define when linking against static liblzma on
platforms like Windows. Most developers don't need to
care about LZMA_API_STATIC at all.

99c1c2abfa Updated the x86 assembler code: 
- Use call/ret pair to get instruction pointer for PIC.
  - Use PIC only if PIC or __PIC__ is #defined.
  - The code should work on MinGW and Darwin in addition
    to GNU/Linux and Solaris.

22a0c6dd94 Modify LZMA_API macro so that it works on Windows with 
other compilers than MinGW. This may hurt readability
of the API headers slightly, but I don't know any
better way to do this.

6a2eb54092 Add LZMA_API to liblzma API headers. It's useful at least 
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h
has to be #included separately where needed.

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.

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.
