  BackupStoreRefCountDatabase: new file format

This format includes an embedded client store marker, which is useful on S3
stores to verify that we haven't downloaded an old version of the refcount DB,
particularly if it was repaired by checking the account, and subsequently not
propagated due to Amazon S3's eventual (not immediate) consistency.

    M test/bbackupd/testbbackupd.cpp

  Log Message:
  -----------
  ServerControl: add signal checks and wait() wrapper

KillServer: add a parameter to allow the expected exit signal to be checked.
This allows us to determine if a process died for the wrong reason, e.g. if it
failed to catch SIGTERM, or was killed by SIGSEGV instead.

WaitForProcessExit: split out, to make it easier to clean up after forked
daemons, and check their exit status and signal.

test/bbackupd: use these to improve handling and failure mode checking of
forking daemon tests, reducing risk of hangs.
