734dbfa590 sched: Make the scheduler object static
Each type of scheduler implements its own static scheduler_t object and
returns a reference to it.

This commit also makes it a const pointer that is it can only change inside
the scheduler type subsystem but not outside for extra protection.

84d18f70f3 sched: Always call on_channel_free() regardless of state
A channel can bounce in the scheduler and bounce out with the IDLE state which
means that if it came in the scheduler once, it has socket information that
needs to be freed from the global hash table.

7cc9621d11 sched: Add Schedulers torrc option
This option is a list of possible scheduler type tor can use ordered by
priority. Its default value is "KIST,KISTLite,Vanilla" which means that KIST
will be used first and if unavailable will fallback to KISTLite and so on.

a06f2a0509 sched: Fallback to naive approach if no runtime KIST support
It is possible that tor was compiled with KIST support but the running kernel
has no support for it. In that case, fallback to a naive approach and flag
that we have no kernel support.

At this commit, if the kernel support is disabled, there are no ways to come
back from it other than restarting tor with a kernel that supporst KIST.

b2c56eacdd sched: Remove vanilla sched options that will be going away
- massive change to src/tgest/test_options.c since the sched options
  were added all over the place in it
- removing the sched options caused some tests to pass/fail in new ways
  so I assumed current behavior is correct and made them pass again
   - ex: "ConnLimit must be greater" lines
   - ex: "Authoritative directory servers must" line
- remove test_options_validate__scheduler in prep for new sched tests

e31a7be161 Make NETINFO clock skew detection work on clients
An unnecessary routerlist check in the NETINFO clock skew detection in
channel_tls_process_netinfo_cell() was preventing clients from

e05414d241 Fix several places where md-using relays would get wrong behavior.
This patch replaces a few calls to router_get_by_id_digest ("do we
have a routerinfo?") with connection_or_digest_is_known_relay ("do
we know this relay to be in the consensus, or have been there some
time recently?").

Found while doing the 21585 audit; fixes bug 23533.  Bugfix on
0.3.0.1-alpha.

5cc80692b8 prop224: Fix memleak in client_get_random_intro().
The memleak was occuring because of the way ExcludeNodes is handled in
that function. Basically, we were putting excluded intro points extend
infos in a special variable which was never freed. Also, if there were
multiple excluded intro points then that variable was overwritten
everytime leaking more memory. This commit should fix both issues.

This commit adds a pretty advanced test for the client-side making sure that
picking intro is done properly.

This unittest also reveals a memleak on the client_pick_intro() function which
is fixed by the subsequent commit.
