Log invalid conf settings as an error

Browse source 
This is not a warning, _parse_options() returns failure without even
parsing further lines and the attempted pacman/pacman-conf program
execution immediately aborts. Warnings are for when e.g. later on if we
don't recognize a setting at all, we skip over it and have enough
confidence in this to continue executing the program.

The current implementation results in pacman-conf aborting with:

warning: config file /etc/pacman.conf, line 60: invalid value for 'ParallelDownloads' : '2.5'
error parsing '/etc/pacman.conf'

or pacman -Syu aborting with the entirely more cryptic:

warning: config file /etc/pacman.conf, line 59: invalid value for 'ParallelDownloads' : '2.5'

and this isn't just a problem for the newly added ParallelDownloads
setting, either, you could get the same problem if you specified a
broken XferCommand, but that's harder as it's more accepting of input
and you probably don't hit this except with unbalanced quotes.
