gdbmtool: accept commands from command line as well as from file

Commands can be supplied to gdbmtool in three ways:

 1. From a file, using the --file (-f) option:

     gdbmtool -f comfile

 2. From the command line, if first argument is the database name:

     gdbmtool test.db count \; fetch mykey \; avail

    Note the use of semicolon to delimit commands.

 3. From the interactive shell, if neither of the above is used.
