Avoid a compilation warning on macOS in scheduler_ev_add()
...
This warning is caused by a different tv_usec data type on macOS
compared to the system on which the patch was developed.
Fixes 23575 on 0.3.2.1-alpha.

sched: BUG() on event_add() and log_warn next_run
...
It is highly unlikely to happen but if so, we need to know and why. The
warning with the next_run values could help.

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.

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.

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.
