Good, the .dectmp cleanup on error is handled now - thanks for fixing that from
v1.

The blob decryption computes csum/size here but they seem to be unused? the
new_manifest and the add_file() calls for blobs only appear in patch 27.  At
this commit the decrypted file replaces the encrypted one on disk, but the
manifest still carries the encrypted file's checksum.
Consider squashing the manifest registration into this commit, or at least
comment that this is intentionally "disarmed" and completed by the later patch
(similar to how patch 23 documents it for the index writer).
