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.

better way to do this.

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.

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.

e114502b2b Oh well, big messy commit again. Some highlights: 
- Updated to the latest, probably final file format version.
  - Command line tool reworked to not use threads anymore.
    Threading will probably go into liblzma anyway.
  - Memory usage limit is now about 30 % for uncompression
    and about 90 % for compression.
  - Progress indicator with --verbose
  - Simplified --help and full --long-help
  - Upgraded to the last LGPLv2.1+ getopt_long from gnulib.
  - Some bug fixes
