* decompression to counter the effects of padding which might be
* added to the compressed buffer and which, if unhandled, would
* confuse the hell out of our decompression function.
* The exact compressed size is needed by the decompression routine,
* so it is stored at the start of the buffer. Note that this may be
* less than the compressed block size, which is rounded up to a
* multiple of 1<<ashift.
