paycheck: unit tests + fixes to checker module
This adds missing unit tests for the checker module, bundled with fixes
to some bugs that surfaced due to unit tests. This includes:
* A fake extent (signified by start_block == UINT64_MAX) that
accompanies a signature data blob bears different requirements than
previously implemented. Specifically, the extent sequence must have
exactly one extent; and the number of blocks is not necessarily one,
rather it is the correct number that corresponds to the actual length
of the signature blob.
* REPLACE/REPLACE_BZ operations must contain data.
* MOVE operation validation must ensure that all of the actual message
extents are being used.
* BSDIFF operation must contain data (the diff).
* Signature pseudo-operation should be a REPLACE.
