ae394bff7c kernel: add support for event objects
Threads may wait on an event object such that any events posted to
that event object may wake a waiting thread if the posting satisfies
the waiting threads' event conditions.

The configuration option CONFIG_EVENTS is used to control the inclusion
of events in a system as their use increases the size of
'struct k_thread'.

cc8ab95760 tracing: Add user-definable tracing interface
Create a new tracing option TRACING_USER that allows
the user to define certain user_sys_trace_... functions
to perform whatever work desired for tracing when
tasks are swiched in/out, during isr enter/exit, and when
cpu is idle.

This infrastructure can be useful for plugging into
locally defined tracing tools or any user-specific
debugging environment.
