After connectivity problems, only try connecting to bridges which
are currently configured; don't mark bridges which we previously
used but are no longer configured. Fixes 14216. Reported by
and fix provided by arma.
If the returned value of read/recv is 0 (meaning EOF), we'll end up in an
infinite loop (active wait) until something is written on the pipe which is
not really what we want here especially because those functions are called
from the main thread.

It's now possible to use SocksPort or any other kind of port that can use a
Unix socket like so:
SocksPort unix:/foo/bar/unix.sock

Introduces two new circuit status name-value parameters: SOCKS_USERNAME
and SOCKS_PASSWORD. Values are enclosing in quotes and unusual characters
are escaped.
Example:
650 CIRC 5 EXTENDED [...] SOCKS_USERNAME="my_username" SOCKS_PASSWORD="my_password"
Here is why:
1) v0 descriptors are deprecated since 0.2.2.1 and not suppose to be alive
in the network anymore. This function should only serve v2 version for now
as the default.
2) It should return different error code depending on what's the actual
error is. Right now, there is no distinction between a cache entry not found
and an invalid query.
3) This function should NOT test if the intro points are usable or not. This
adds some load on a function that should be "O(1)" and do one job.
Furthermore, multiple callsites actually already test that doing twice the
job...
4) While adding control event, it would be useful to be able to lookup a
cache entry without having it checking the intro points. There are also
places in the code that do want to lookup the cache entry without doing
that.

If --disable-systemd is given, $enable_systemd is set to "no", not "false".
As a result, if libsystemd is found, we still turn on systemd support even
if we explicitly disable it with --disable-system.
