97cb302c0e sftp: fix buffer_unpack argument to be char** rather than char*
Summary:
buffer variable 's' gets unpacked as char**, the previous code was passing
a char* causing segfaults on all readlink calls inside the unpacking code

Test Plan:
- without patchy examples/samplesftp segfaults in readlink
- with patchy it doesn't

e9b44d26b1 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

9f5f10552b 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.
