Revised the Delta filter implementation. The initialization function is still shared between encoder and decoder, but the actual coding is in separate files for encoder and decoder. There are now separate functions for the actual delta calculation depending on if Delta is the last filter in the chain or not. If it is the last, the new code copies the data from input to output buffer and does the delta calculation at the same time. The old code first copied the data, then did the delta in the target buffer, which required reading through the data twice. Support for LZMA_SYNC_FLUSH was added to the Delta encoder. This doesn't change anything in the file format.

Put the interesting parts of XZ Utils into the public domain. Some minor documentation cleanups were made at the same time.

Added lzma_delta_coder_memusage() which also validates the options.

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.

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.
