(Specifically, carriage return after a quoted value in a config
line. Fixes bug 19167; bugfix on 0.2.0.16-alpha when we introduced
support for quoted values. Unit tests, changes file, and this
parenthetical by nickm.)
This is a kludge to deal with the fact that `tor_addr_t` doesn't contain
`sun_path`. This currently ONLY happens when circuit isolation is being
checked, for an isolation mode that is force disabled anyway, so the
kludge is "ugly but adequate", but realistically, making `tor_addr_t`
and the AF_UNIX SocksPort code do the right thing is probably the better
option.
Closes ticket 20303.
The LIBRESSL_VERSION_NUMBER check is needed because if our openssl
is really libressl, it will have an openssl version number we can't
really believe.
Previously, we would reject even rendezvous connections to IPv6
addresses when IPv6Exit was false. But that doesn't make sense; we
don't count that as "exit"ing. I've corrected the logic and tried
to make it a lottle more clear.
Fixes bug 18357; this code has been wrong since 9016d9e829 in
0.2.4.7-alpha.
When deleting unsuitable addresses in get_interface_address6_list(), to
avoid reordering IPv6 interface addresses and keep the order returned by
the OS, use SMARTLIST_DEL_CURRENT_KEEPORDER() instead of
SMARTLIST_DEL_CURRENT().

We removed that feature in 0.2.4.2-alpha, but some comments seem to
have lingered.
I didn't add a changes/ file since this is just internal code cleanup.
The client addr is essentially meaningless in this context (yes, it is
possible to explicitly `bind()` AF_LOCAL client side sockets to a path,
but no one does it, and there are better ways to grant that sort of
feature if people want it like using `SO_PASSCRED`).
As before, we check server protocols whenever server_mode(options)
is true and we check client protocols whenever server_mode(options)
is false.
Additionally, we now _also_ check client protocols whenever any
client port is set.
(Technically, we could just remove extend2 cell checking entirely,
since all Tor versions on our network are required to have it, but
let's keep this around as an example of How To Do It.)
(Despite the increased size of the consensus, this should have
approximately zero effect on the compressed consensus size, since
the "proto" line should be completely implied by the "v" line.)
