3778db1be5 liblzma: Make the use of lzma_allocator const-correct. 
There is a tiny risk of causing breakage: If an application
assigns lzma_stream.allocator to a non-const pointer, such
code won't compile anymore. I don't know why anyone would do
such a thing though, so in practice this shouldn't cause trouble.

Thanks to Jan Kratochvil for the patch.

0d21f49a80 liblzma: Fix decoding of LZMA2 streams having no uncompressed data. 
The decoder considered empty LZMA2 streams to be corrupt.
This shouldn't matter much with .xz files, because no encoder
creates empty LZMA2 streams in .xz. This bug is more likely
to cause problems in applications that use raw LZMA2 streams.

0076e03641 Clean up a few FIXMEs and TODOs. 
lzma_chunk_size() was commented out because it is
currently useless.

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.

cd70801520 LZMA2 decoder cleanups. Make it require new LZMA properties 
also in the first LZMA chunk after a dictionary reset in
uncompressed chunk.

3b34851de1 Sort of garbage collection commit. :-| Many things are still 
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.
