Patch by Nico <nsabbi@libero.it>

this patch fixes a recently discovered bug for which DVB-C users
couldn't tune
(wrong parsing of the config file and incorrect parameter passing to
tune_it())
and includes the still unapplied patch posted in date 6/9/2003:

-  it works correctly with and without caches; in the former case it
doesn't take anymore a lot of time to empty the cache before changing channel;
the uninit_cache() function is called in mplayer.c just after
the new tuning operation
- initialized a variable identifying the tuner type, and exit if it
isn't supported


- doesn't crash anymore when
1) the channels file doesn't exists
2) the tuner is used by another application
3) in the menu, when trying to select a channel before the first
4) some mp_msg() called in case of error
