posix: separate shell utilities and posix api implementation 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. Signed-off-by: Christopher Friedt <cfriedt@meta.com>

posix: add Kconfig.deprecated There will be some POSIX Kconfig symbols that will be deprecated in favour of Kconfig symbols that are exact matches for those in the POSIX specification (1003.1-2017). Create the empty Kconfig file now, and then incrementally add to it as non-standard POSIX Kconfig options are replaced with standard-like POSIX Kconfig options.

posix: add stubs for asynchronous io Add stubs for POSIX asynchronous io that return -1 and set errno to ENOTSUP. The functions and structures in aio.h are required by the _POSIX_ASYNCHRONOUS_IO Option as detailed in Section E.1 of IEEE-1003.1-2017. The _POSIX_ASYNCHRONOUS_IO interface is required for PSE51, PSE52, PSE53, and PSE54 conformance, and is otherwise mandatory for any POSIX conforming system as per Section A.2.1.3 of IEEE-1003-1.2017.

libc: common: implement multiple time functions Implemented the following: - `asctime_r()` - `asctime()` - `localtime()` - `localtime_r()` - `ctime()` - `ctime_r()` Specifically: - the implementation of `localtime()` & `localtime_r()` simply wraps around the gmtime() & gmtime_r() functions, the results are always expressed as UTC. - `ctime()` is equivalent to `asctime(localtime(clock))`, it inherits the limitation of `localtime()` as well, which only supports UTC results currently. Added tests for these newly implemented functions. Signed-off-by: Yong Cong Sin <ycsin@meta.com> Signed-off-by: Yong Cong Sin <yongcong.sin@gmail.com>

posix: deprecate POSIX_FNMATCH GETOPT GETENTROPY The functions fnmatch(), getopt(), getentropy() and others are grouped into the standard Option Group POSIX_C_LIB_EXT. The getentropy() function is currently in-draft for Issue 8 as of 2021. https://www.opengroup.org/austin/docs/austin_1110.pdf Not surprisingly, the POSIX_C_LIB_EXT Option Group also includes the highly debated strnlen() function.

posix: deprecate POSIX_MAX_FDS and add POSIX_DEVICE_IO 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 simply removing "CONFIG": * CONFIG_POSIX_OPEN_MAX 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(), ..). Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>

posix: fd_mgmt: add fd_mgmt option group 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. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>

posix: allow for external implementation of option groups Make it easier for external C libraries, toolchains, and integrators to override Zephyr's implementation of functions and sybmols on a per-Option-Group basis. This change adds a number of non-user-configurable Kconfig options that block internal Cmake rules from building Zephyr's C sources corresponding to the particular option. This is useful, for example, if a specific C library has a smaller, or faster, or more secure version of some symbols belonging to a a particular option group.
