0b634793cc lib: posix: Update to new timeout API
Mostly trivial search-and-replace, except for pthread_rwlock.c, where
we need spread timeout over 2 semaphore operations.

17b19eb810 pthread: add setname/getname glibc extensions
Adding the ability to set and get pthread names by defining
some non-standard extension functions that were first
introduced by Glibc.

Similar to zephyr thread naming, these allow for thread
tracking and debugging even when using the more portable
posix API.

Though Glibc was the originator, the current POSIX functions
have return codes based on Oracle's adopted spec, so these
functions follow suit.  The Oracle and Glibc function
prototypes match.

5b3df8a180 posix: pthread_create: Ignore retval of pthread_mutex_init() calls
pthread_mutex_init() just redirects to Zephyr kernel primitive, for
initializing structure fields. So, use the knowledge that it can't
fail (for as long as structure pointer is initialized, and here it's
from pre-allocated array), and ignore return value of
pthread_mutex_init()

6922d93d8e lib/posix: correct the meaning of CONFIG_MAX_PTHREAD_COUNT
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.

bcdfa76ff3 lib: posix: Fix pthread_attr_init() return code
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.
