[PATCH] Add aliases "i ty" and "i so".

[Doug Evans <xdje42 at gmail dot com>]

Hi.

I'd gotten tired enough of fully typing out "info types" and "info source"
(which otherwise collide with "info type-printers" and "info sources")
that I have this in my .gdbinit:

alias i ty = info types
alias i so = info source

Does anyone want a more generally available solution?
Another way to go is to put the "alias" solution in a more public
place (the faq or some such).
I don't have a strong preference, just in a "spring cleaning" kind of
mood. :-)

I thought of maybe "i t" for "info types" but I can't think of a reason
to prefer "t" for "types" or "threads", so I'm going with "ty" which
I think is pretty safe.

"s" is taken ("info stack", which is fine by me), so I went with "so"
for "source".
