Added 4 new pthread_key APIs for thread-specific data
key creation, deletion, setting and getting the values.
Added a key list to the posix_struct for threads.
Added pthread_once API.

The pthread mutex changes went in with an adaptation to build with the
new wait queue API, but they did it by using the old dlist hooks
directly through typecasting and union assignment. That... is sort of
the opposite of the intent to having the new API be abstracted. The
pthread code worked, but failed once wait queues (on x86) stopped
being dlists.
Simple fix once I saw the problem, anyway.

There were multiple spots where code was using the _wait_q_t
abstraction as a synonym for a dlist and doing direct list management
on them with the dlist APIs. Refactor _wait_q_t into a proper opaque
struct (not a typedef for sys_dlist_t) and write a simple wrapper API
for the existing usages. Now replacement of wait_q with a different
data structure is much cleaner.
Note that there were some SYS_DLIST_FOR_EACH_SAFE loops in mailbox.c
that got replaced by the normal/non-safe macro. While these loops do
mutate the list in the code body, they always do an early return in
those circumstances instead of returning into the macro'd for() loop,
so the _SAFE usage was needless.

Move posix layer from 'kernel' to 'lib' folder as it is not
a core kernel feature.
Fixed posix header file dependencies as part of the move and
also removed NEWLIBC related macros from posix headers.

This patch provides POSIX sleep APIs for POSIX 1003.1 PSE52 standard.
sleep(n) is implemented using Zephyr k_sleep API.
uleep(n) is implemented using Zephyr k_sleep/k_busy_Wait API.

As per POSIX standard typedef should be part of sys/types.h file.
So moving typedef from pthread.h to sys/types.h file.

As per IEEE 1003.1 POSIX APIs should return ERROR_CODE on error.
But currently these are returning -ERROR_CODE instead of ERROR_CODE.
So fixing the return value.

Having posix headers in the default include path causes issues with the
posix port. Move to a sub-directory to avoid any conflicts.
