After profiling many iterations of several driver operations, the
observed absolute maximum number of queue scheduler messages was 452
during soft AP startup. Typical maximums for this test case are less
than 100, occasionally getting as high as 250. The median for all of
the driver operations in general were in the range of 1-2. Given this
information, a round number around twice the worst case rate was
picked.
Reduce SCHEDULER_CORE_MAX_MESSAGES to 1000, down from 8000 for MCL.
This saves a significant amount of unused statically allocated memory.

Part of the scheduler component has been migrated to the new sched_*
logging wrappers, but part of it still remains to be ported. Finish
migrating all of the scheduler logging APIs.

Reduced the number of scheduler message buffers for WIN to
2k from 4k since WIN is only using 2 scheduler queues.
Changed the order of two members of scheduler messgae structure
to avoid additional padding on 64bit platform.

A commonly used and robust life-cycle pattern consists of the following
4 steps:
1) create (allocate resources)
2) start (mark resources as safe for use)
3) stop (mark resources as unsafe for use)
4) destroy (deallocate resources)
This pattern effectively prevents access to uninitialized and freed
resources. While the dispatcher psoc life-cycle follows this pattern,
the global life-cycle is condensed into steps 1 and 4. Unsurprisingly,
this led to uninitialized and freed resource access problems, especially
in regards to the scheduler thread.
Split the scheduler init and deinit life-cycle functions into init,
enable, disable, and deinit. Create new global enable and disable
dispatcher functions, and call the new scheduler APIs as appropriate.
This brings the global dispatcher life-cycle in line with the existing
psoc life-cycle, and prevents many scheduler related resource access
issues.

A set of logging helpers for the scheduler component were previously
added to reduce boilerplate logging code. Update scheduler_api.c to use
the new logging helpers.

In order to catch long running scheduler messages, start a watchdog
timer before processing each message, and stop the timer after each
message is processed. When the watchdog timer expires, immediately
crash the device in debug builds for easier debugging.

Add provision for flush callback in scheduler message such that
during driver unload scheduler can invoke the flush callback and
components can release the common object ref count which is taken
before posting the message.
