hciconfig list commands (patch)

Dear All,

I'd like to offer a small patch to tools/hciconfig.c (and the man page).

Currently, running the command "hciconfig hci0 commands" creates a list 
of supported codes and their names in this format[1]. It's rather tricky 
to interpret this format, when trying to discover the command code for a 
particular named action, because both lists are very long, and run 
consecutively rather than concurrently.

My patch adds an extra command ""hciconfig hci0 commands_list", which 
hopefully makes this clearer, emitting output in the format of [2].

I hope this is helpful :-)

If it's necessary to have a legal declaration, then I hereby state for 
the record that I, Richard Neill, wrote the attached code, and I release 
it under the GPL 2+.

P.S. This is my contribution to bluez, so I hope I'm sending the right 
format to the right place.  If I could do this better, I'd welcome 
feedback off-list.
