This patch implements a new Multi Level Command called: 'info' into 
fhpd.  This new multi level command attempts to group all the 
'information-providing' commands into one command-group. This is so the 
main top-level command's help does not get unwieldy. The commands auxv, 
maps and debuginfo registrations have been moved into info command. The 
regs command registration has been duplicated into info command due to 
the hpd specifying the regs command should also be a top-level command.

Usage Scenarios:

Usage: info help - will print out all the information sub-commands that 
info knows about.

Usage: info help <sub-command> - will print out the sub-command's help. 
E.g. info help regs

Usage: info <sub-command> -help. Same as above. E.g. info regs -help

Usage: info <sub-command>  - will execute the sub-command. E.g. info auxv.


Class usage:

To add commands to 'info', simple edit the InfoCommand.java as show in 
the patch, or call the .add() function.

Known bugs:

An unsolved issue is that info -help does not parse the -help correctly 
and identifies it as a command. Extending ParameterizedCommand instead 
of Command leads to the InfoCommand cannibalizing command options that 
the sub-command should process.
