LZMA: Add a version of ulzma which takes the input and output buffer sizes. This new version is used to implement the version which doesn't take the input and output buffer sizes.

If the size the lzma header claims it needs is bigger than the space we have, print a message and continue rather than erroring out. Apparently the encoder is lazy sometimes and just puts a large value there regardless of what the actual size is. This was the original intention for this code, but an outdated version of the patch ended up being submitted.
