Version 1.22
* Fix file header validation
* Fix key verification in sequential access
* Fix testing with DejaGNU 1.6.3
* Fix stack overflow in print_usage
* Fix a leak of avail entry on pushing a new avail block
The leak would occur if the original avail table had odd number of entries.
* New gdbmtool variables: errorexit, errormask, trace, timing
"Errorexit" and "errormask" control which GDBM errors would cause the
program termination and emitting a diagnostic message,
correspondingly. Both variables are comma-delimited lists of error
codes.
The "trace" variable enables tracing of the gdbmtool commands.
The "timing" variable, when set, instructs gdbmtool to print time
spent in each command it runs.
* New gdbmtool options: -t (--trace), and -T (--timing)
