The VARBLOCK file format
--------------------------------------------------
The VARBLOCK file format allows us to encrypt files that are larger
than the RSA key. The format is as follows; || denotes byte string
concatenation::
VARBLOCK := VERSION || BLOCK || BLOCK || ...
VERSION := 1
BLOCK := LENGTH || DATA
LENGTH := varint-encoded length of the followng data, in bytes
DATA := the data to store in the block
The varint-format was taken from Google's Protobuf_, and allows us to
efficiently encode an arbitrarily long integer.
