card: Implement non-interactive mode.

Browse source 
* tools/card-tool.h (opt): Add field 'initialized'.
* tools/card-call-scd.c (scd_learn): Set it.
* tools/gpg-card-tool.c (main): Reworked.
(dispatch_command): New.
--

This work is not yet finished because most commands need some tweaks
for non-interactive work.  What you already can do are things like:

 $ gpg-card-tool list -- 'auth <oldkey' \
   -- auth --setkey --raw 123456781234567812345678 -- help auth

Which will list the current card, authenticate using a hex encoded key
from the file "oldkey", set the new admin key to "123...78", and print
help for the auth command.  Note that the -- acts as a delimiter
between commands.  To use a double dash as argument to a command the
entire command must be quoted.
