Makes the purpose and capabilities of the kernel event logger
clearer, and leaves much of the low-level detail relating to
use of the configuration options and APIs to the configuration
option guide and API guide, respectively. Also corrects some
bugs in the example code for retrieving event information.

Also updates the API guide to make a clear distinction between
the general purpose event logger framework and the kernel event
logger (which is a specific instance of this framework).

Prepares the kernel event logger APIs for inclusion in the
API guide. Also corrects a couple of other issues:

* Gets rid of obsolete thread monitor code.
* Renames "timer_func" global variable to "_sys_k_timer_func"
  to align it with kernel naming conventions.

Since it is not possible to continue execution it is better

Coverity complained about the use of strncpy() to fill up a buffer of
size N with a string of the same size didn't leave room for the final
\0.

This is a valid concern; however, the usage is valid too, as the
writer intended to create a pattern that later can be tested--addind a
\0 would break the pattern.

So instead, use memcpy() for the same function.

Pinmux driver almost certainly should be initialized before the
rest of hardware devices (which may need specific pins already
configured for them), and usually after generic GPIO drivers.
Thus, its priority should be between KERNEL_INIT_PRIORITY_DEFAULT
(default 40) and KERNEL_INIT_PRIORITY_DEVICE (default 50). Thus,
we set PINMUX_INIT_PRIORITY to 45.

There are exceptions to the rule above for particular boards. For
example, BOARD=galileo has GPIO and pinmuxer on I2C bus and thus
overrides PINMUX_INIT_PRIORITY to be much higher. Note that while
PINMUX_INIT_PRIORITY was defined previously (at 60), it was used
only for galileo, which overrides it anyway.

This fix was prompted by investigation why eth_ksdk driver was
non-functional after kernel priorities re-hashing: both eth_ksdk
and pinmux used the same priority, and eth_ksdk happened to run
before pinmux. While bumping eth_ksdk priority would help in the
particular case, the same would likely reoccur with other drivers
like I2C, SPI, etc.

Rewrites the example of a timer's expiry routine offloading
processing that can't be done at interrupt level. The example
now submits work to the system workqueue directly, rather than
using an alert. This saves footprint by eliminating the need
for alert-related API support that isn't needed. (This is a
true savings, since the alert code just called the same
workqueue APIs the example now calls directly.)

This commit fixes an issue in the test_ccm_mode.c file:

sizeof(data) is used to compute the length of the array pointed to
by the 'uint8_t *data' pointer.

At the same function scope, there is a variable (dlen) that already
specifies the required length, so we use that variable instead of
the 'sizeof' function call.
