- Convert more atoi to str_to_int64() for DB.

- Convert more atoi to str_to_int64() for DB.
- Implement filling in NumVols by querying DB rather
  than trying to keep track of it.
- Add storage name to string passed to in use storage=
- Fix newVolume() so that the Python script is always
  called.
- Fix handling of pool,PoolId, and storage in ua_output.
- Same fix in ua_status.c
- Remove required locking of resources
- Replace pthread_cond_signal() by pthread_cond_broadcast()
  hoping to fix the /lib/tls hang problems (lost signal).
- Move resource locking seaching from parse_conf.c to res.c
  in src/lib.
- Modify end of volume handling so that fixup_... does not
  redo what block.c has already done -- writing Vol info to
  DIR. This fixes a bug with bad numbers of files on a tape
  when it filled as reported by Peter.
- In release_device() do not update the DIR on the Volume
  info if the the information was already written at the
  end of the tape.
