04e290a19b config: Parse Match keyword 
Amends f818e63f8, which introduced the constants and matching of this
configuration option, but did not implement the handling of the values
which was causing the configuration parser failing for certain
configurations.

This commit exposes match_pattern_list() from match.c

bad407f5e2 config: Do not overwrite previously matched result in Host blocks 
The match_hostname() expects comma separated list, while the Host
config keyword in openssh uses spaces separated list by default.
Therefore any subseqent match or negated match in space separated
list will overwrite the previous matches.

This also adjusts the tests to make sure both of the versions work.
