Subject: options: change --no-config option, make it apply to input.conf as
 well

Simplify --no-config and make it a normal flag option, and doesn't take
an argument anymore. You can get the same behavior by using --no-config
and then --include to explicitly load a certain config file.

Make --no-config work for input.conf as well. Make it so that
--input:conf=file still works in this case. As a  technically unrelated
change, the file argument now works as one would expect, instead of
making it relatively to "~/.mpv/". This makes for simpler code and
easier to understand option semantics. We can also print better error
messages.
