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.

Added initial support for preset dictionary for raw LZMA1

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.

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.

Updated src/liblzma/Makefile.am to use liblzma.pc.in, which

should have been in the previous commit.

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.

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.

be added back in some form later, but the current version
