Add key management system

This adds a key management system that stores (currently) two data
encryption keys of length 128, 192, or 256 bits.  The data keys are
AES256 encrypted using a key encryption key, and validated via GCM
cipher mode.  A command to obtain the key encryption key must be
specified at initdb time, and will be run at every database server
start.  New parameters allow a file descriptor open to the terminal to
be passed.  pg_upgrade support has also been added.
