broken. API has changed a lot and it will still change a
little more here and there. The command line tool doesn't
have all the required changes to reflect the API changes, so
it's easy to get "internal error" or trigger assertions.

literal coder as part of the main LZMA encoder or
decoder structure.
Make the LZMA decoder to rely on the current internal API
to free the allocated memory in case an error occurs.

misunderstanding of the code. There's no tiny fix for this
problem, so I also cleaned up the code in general.
This reduces the speed of the encoder 2-5 % in the fastest
compression mode ("lzma -1"). High compression modes should
have no noticeable performance difference.
This commit breaks things (especially LZMA_SYNC_FLUSH) but I
will fix them once the new format and LZMA2 has been roughly
implemented. Plain LZMA won't support LZMA_SYNC_FLUSH at all
and won't be supported in the new .lzma format. This may
change still but this is what it looks like now.
Support for known uncompressed size (that is, LZMA or LZMA2
without EOPM) is likely to go away. This means there will
be API changes.

word literal instead of char for better consistency.
There are still some names with _char instead of _literal
in lzma_optimum, these may be changed later.
Renamed length coder variables.
This commit doesn't change the program logic.

lzma_encoder_init.c. While we don't call
fill_distances_prices() and fill_align_prices() in
lzma_lzma_encoder_init(), we still need to initialize
these two variables so that the fill functions get
called in lzma_encoder_getoptimum.c in the beginning
of a stream.

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.
