move misc/slist.h to sys/slist.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Current code implement CONFIG_MAX_PTHREAD_COUNT as the maximum number
of POSIX threads that can ever be created, rather than the maximum
number of active POSIX threads. Use pthread_state of struct posix_thread
to track the state of posix thread in posix_thread_pool so that we can
reuse the unused posix thread.
Fixes#15516.

According with MISRA-C the value returned by a non-void function has
to be used. As memcpy return is almost useless, we are explicitly
ignoring it.

Calling pthread_join() with current thread would lead
to deadlock. Adding check for it and to return
appropriate error code.

ENOTSUP is not being used correctly in
pthread_attr_setschedparam(), hence
replaced its check for EINVAL instead.

Added EAGAIN error code in pthread_create()
with fixing the EINVAL return as it is
limited to attribute checking.

The memory occupied by posix_thread objects are not significant.
Hence, no point in using dynamic allocation.

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.

pthread_attr_init() should not return EBUSY as per POSIX spec
so fixed this by return ENOMEM if the attr pointer is NULL.
Also fixed the attribute initialization logic by copying the
init_pthread_attrs to the attr.

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.
