Added conditionally enabled event state tracing support.
Needed for enhanced debug visibility of tight timed events where
normal print debug messages affect the timing of things. This is a
simple buffer that allows post analysis via gdb of what sequencer
events occurred.

- Removed some debug output and changed the level of others to reduce
the amount of information logged. The reason is that some of this is
causing false positive distractions.
- Removed enabling of FILTER error IRQ events. It isn't needed and is
only informational.
- Changed frame control AR bit inspection to use native retrieval
routine.
- Addressed some coding style issues.

- Reworked the driver logic around TX/RX to correctly handle the
expectations of the underlying 802.15.4 hardware IP.
- Fixed a problem with TX always reporting an error to the stack
which resulted in constant retries.
- Fixed bug in RX to TX transition which would occasionally cause the
driver to error the TX.
- Changed RX logic to ensure that invalid RX frames were not passed up
the stack.
- Simplified hardware timer usage to only use TMR3.
- Added RX watermark and TMR3 support to fix a hardware problem where
the hw IP can get stuck on a receive in noisy environments.
- Modified samples/net/echo_client and echo_server kw41z project config
files to provide enanced debug visibility into stacks and threads.
