Move somewhat useful (but private and internal functions) that deal
with struct timespec to posix_clock.h until there is a better API
available for dealing with operations on struct timespec.

Add a common private function timespec_is_valid() that
can be used to check if a timespec object is valid, and
use that consistently in lib/posix/options.

If it is not possible to create a timer in timer_create(),
then the timer_obj associated with the timer must be freed.
However, the address of the pointer was mistakenly being
passed to k_mem_slab_free() rather than simply the
the pointer.
This caused a crash in tests which can easily be avoided
by passing the pointer rather than the address of the
pointer.

For SIGEV_SIGNAL, the function zephyr_timer_wrapper() is the handler
between kernel and posix layer.
Here, for one-time timer, reload is equal to 0 and function returns.
As a consequence, handler function was never called.

options/fs.c and options/timer.c both use POSIX-only functions. To ensure
those symbols are visible from the underlying C library, define
_POSIX_C_SOURCE.

The POSIX_CLOCK option does not correspond to any standard
option. It was used to active features of several distinct
POSIX Options and Option Groups, which complicated API and
application configuration as a result.
POSIX_CLOCK is being deprecated in order to ensure that Zephyr's
POSIX Kconfig variables correspond to those defined in the
specification, as of IEEE 1003.1-2017.
Additionally, CONFIG_TIMER is being deprecated because it does
not match the corresponding POSIX Option (_POSIX_TIMERS).
With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":
* CONFIG_POSIX_TIMERS
Similarly, we introduce the following Kconfig options that
map directly to standard POSIX Options by simply removing
"CONFIG":
* CONFIG_POSIX_CLOCK_SELECTION
* CONFIG_POSIX_CPUTIME
* CONFIG_POSIX_DELAYTIMER_MAX
* CONFIG_POSIX_MONOTONIC_CLOCK
* CONFIG_POSIX_TIMEOUTS
* CONFIG_POSIX_TIMER_MAX
In order to maintain parity with the current feature set, we
introduce the following Kconfig options that map directly to
standard POSIX Option Groups by simply removing "CONFIG_":
* CONFIG_POSIX_MULTI_PROCESS - sleep()
Similarly, in order to maintain parity with the current feature
set, we introduce the following additional Kconfig options that
map directly to standard POSIX Options by simply removing
"CONFIG":
* CONFIG_XSI_SINGLE_PROCESS - gettimeofday()

Previously, the POSIX shell utilities were intermixed with the
POSIX API implementation.
The POSIX shell utilities only depend on the public POSIX API,
so it makes sense to keep them in a separate subdirectory.
