Note the addition of the sub-file incrementals feature, and include a
script for upgrading the local database to the new format.

Fix a bug in signature loading for sub-file incrementals.
Signatures for sub-file chunks were being written properly, but were not
being loaded properly (signature data and the algorithm string were
being swapped), so no sub-file incrementals were being generated.

Track quantity of data referenced in old segments more precisely.
When calculating used space in segments, treat a reference to just a subset
of data in an object (for example, with subfile incrementals) as using just
that data, instead of the entire object. This should provide better
information to the segment cleaner.

Initial support for efficient sub-file incrementals.
This is a cleaned-up version of the code written for the OSDI'08
submission to implement sub-file incremental deltas. Large files are
broken into small chunks (in a content-sensitive manner with Rabin
fingerprints, as in LBFS). Hash values are computed for the chunks and
stored in a new database table in the local database. On subsequent
backups, when a file has changed, search for chunks that are identical,
so that portions of old blocks may be re-used even if the entire blocks
cannot be.

Remove some debugging output so backup runs are less verbose.

Put updated copyright statements in all source files.
These now reflect the fact that all code should be distributable under the

Report compressed size of data written in a backup as well as uncompressed.
When exiting, a summary of the size of all segments (grouped by type: data,
metadata, ...) is printed. Extend this so that both the uncompressed and
compressed sizes of the segments are printed, and to do so now also keep
track of the compressed size of data.
