a9e879e273 logging: move sys_log to subsys/logging
Move logging out of misc/ to its own subsystem. Anything related to
logging and any new logging features or backends could be added here
instead of the generic location in misc/ which is overcrowded with
options that are not related to eachother.

954baea90b random: Restructure RANDOM Kconfig
Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu.  Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom.  Do not present pseudo generators if a true random generator
is presented.

This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.

In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.

Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.

a715194d43 random: Rewrite sys_rand32_init() with SYS_INIT()
Use the SYS_INIT() mechanism to invoke the sys_rand32_init() function
in random drivers that require an initializer.  Remove all empty
sys_rand32_init() instances.

The existing explicit sys_rand32_init() function runs immediately after
PRE_KERNEL_2 before stack canaries are initialized.  In order to get
equivalent behaviour with sys_rand32_init() we set SYS_INIT() to
initialize the random drivers at the lowest priority of PRE_KERNEL_2.

bbe84f8ae5 Use ccflags-y and asflags-y instead of EXTRA_CFLAGS
According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build.  This patch converts to them to the newer ccflags-y which also
fixes the problem.

e2fa00be6e Algorithm improvement for timer based random number generator
The timer based pseudo random number generator returns the
number of system clock ticks. If the random number function is
called subsequently in a time less than a system clock tick, it
leads to getting same number.

To prevent this the counter is introduced. Counter gets changed
each call, so it ensures the caller gets different numbers each time
the random number function gets called.
