Combine lzma_options_block validation needed by both Block

encoder and decoder, and put the shared things to
block_private.h. Improved the checks a little so that
they may detect too big Compressed Size at initialization
time if lzma_options_block.total_size or .total_limit is
known.

Allow encoding and decoding Blocks with combinations of
fields that are not allowed by the file format specification.
Doing this requires that the application passes such a
combination in lzma_options_lzma; liblzma doesn't do that,
but it's not impossible that someone could find them useful
in some custom file format.
