Implement the core of the command suite

Implement the core of the command suite.  This includes:

 (*) Standard AFS argument parsing.

 (*) Autogeneration of parsers for commands, based on description in banner
     comments and handler function arguments.

 (*) Bash completion.

 (*) Command suite multiplexing based on argv[0] and argv[1].

 (*) "help" and "apropos" for bos, fs, pts and vos.

Each command must be preceded by a comment that conforms to the following
template:

/***
 * COMMAND: suite command - one-line help
 * ARG: "-switchname"
 * ARG: "-switchname <param-help>"
 * ARG: "-switchname <param-help>+"
