Zephyr's POSIX API is moving toward using the standard
nomenclature from IEEE 1003.1-2017 for as much as possible. In
particular, we want to have consistent naming between Zephyr's
POSIX API Kconfig options and the naming for POSIX Options and
Option Groups.
The Kconfig option CONFIG_PTHREAD_IPC has been (ab)used for a
very long time for a variety of different purposes. However,
the standard Option / feature test macro for POSIX Threads is,
intuitively _POSIX_THREADS. There is a corresponding sysconf()
key named _SC_POSIX_THREADS.
Annoyingly, the POSIX Option Group that corresponds to the
Option is POSIX_THREADS_BASE, which is a minor inconsistency
in the standard.
The _POSIX_THREADS Option already includes mutexes, condition
variables, and thread-specific storage (keys). So with this
change, we also deprecate the redundant Kconfig variables that
do not have a corresponding match in the standard.
- CONFIG_PTHREAD_IPC
- CONFIG_PTHREAD
- CONFIG_PTHREAD_COND
- CONFIG_PTHREAD_MUTEX
- CONFIG_PTHREAD_KEY
Additionally, create Kconfig variables for those configurables
which we are lacking:
- CONFIG_POSIX_THREADS_EXT
- CONFIG_POSIX_THREAD_ATTR_STACKSIZE
- CONFIG_POSIX_THREAD_ATTR_STACKADDR
- CONFIG_POSIX_THREAD_PRIORITY_SCHEDULING
- CONFIG_POSIX_THREAD_PRIO_INHERIT
- CONFIG_POSIX_THREAD_PRIO_PROTECT
- CONFIG_POSIX_THREAD_SAFE_FUNCTIONS
Some Kconfig variables were renamed to more properly match the spec:
- CONFIG_MAX_PTHREAD_COUNT -> CONFIG_POSIX_THREAD_THREADS_MAX
- CONFIG_MAX_PTHREAD_KEY_COUNT -> CONFIG_POSIX_THREAD_KEYS_MAX

The POSIX_MAX_FDS option does not correspond to any standard
POSIX option. It was used to define the size of the file
descriptor table, which is by no means exclusively used by
POSIX (also net, fs, ...).
POSIX_MAX_FDS 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. Namely,
POSIX_OPEN_MAX. CONFIG_POSIX_MAX_OPEN_FILES is being deprecated
for the same reason.
To mitigate any possible layering violations, that option is
not user selectable. It tracks the newly added
CONFIG_ZVFS_OPEN_MAX option, which is native to Zephyr.
With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":
* CONFIG_POSIX_DEVICE_IO
Similarly, with this deprecation, we introduce the following
Kconfig options that map directly to standard POSIX Options by

In order to maintain parity with the current feature set, we
introduce the following Kconfig options.
* CONFIG_POSIX_DEVICE_IO_ALIAS_CLOSE
* CONFIG_POSIX_DEVICE_IO_ALIAS_OPEN
* CONFIG_POSIX_DEVICE_IO_ALIAS_READ
* CONFIG_POSIX_DEVICE_IO_ALIAS_WRITE
Gate open(), close(), read(), and write() via the
CONFIG_POSIX_DEVICE_IO Kconfig option and move
implementations into device_io.c, to be conformant with the
spec.
Lastly, stage function names for upcoming ZVFS work, to be
completed as part of the LTSv3 Roadmap (e.g. zvfs_open(), ..).

With this change, we collect implementations of functions that are
part of the POSIX_FD_MGMT Option Group into one compilation unit
(fd_mgmt.c) and provide a matching Kconfig symbol that is
reflective of the standard.
Additionally, provide Kconfig options for aliases of those functions
since Newlib-based toolchains internally use an underscore-prefixed
alias for many POSIX functions (in this case _lseek).
Prefix Zephyr-native implementations with zvfs_ to prepare for the
up-coming changes in that area.

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

Some POSIX header tests assumed that various structures would be
declared even if POSIX_API=n. Actually most meaningful POSIX
structures are guarded by feature test macros defined by
the implementation (i.e. implementation conformance macros).
So only run tests on those structures when CONFIG_POSIX_API=y.
Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
The header tests for the existence of constants like
_POSIX_SPIN_LOCKS are bound to fail in one circumstance or
another because each of those options are (theoretically)
features which can be enabled or disabled.
Moreover, some implementations (e.g. external libc) might
not implement one particular subset or option group.
These tests are poorly conditioned, so remove them.
