license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

lib: posix: Switch to use zephyr_interface_library_named cmake directive Similar to how other sub-libraries are defined in Zephyr tree, e.g. "fs", "lgvl", etc. This is supposed to help with the need to explicitly add posix include path to each and every application using POSIX subsys.

lib: posix: Add support for eventfd This implements a file descriptor used for event notification that behaves like the eventfd in Linux. The eventfd supports nonblocking operation by setting the EFD_NONBLOCK flag and semaphore operation by settings the EFD_SEMAPHORE flag. The major use case for this is when using poll() and the sockets that you poll are dynamic. When a new socket needs to be added to the poll, there must be some way to wake the thread and update the pollfds before calling poll again. One way to solve it is to have a timeout set in the poll call and only update the pollfds during a timeout but that is not a very nice solution. By instead including an eventfd in the pollfds, it is possible to wake the polling thread by simply writing to the eventfd. Signed-off-by: Tobias Svehagen <tobias.svehagen@gmail.com>

lib: getopt: rework and extend getopt library Getopt has been rework in this way that calling it does not require extra state parameter and its execution is thread safe. Global parameters describing the state of the getopt function have been made available to ensure full API compatibility in using this library. However, referencing these global variables directly is not thread safe. In order to get the state of the getopt function for the thread that is currently using it, call: getopt_state_get(); Extended the library with getopt_long and getopt_long_only functions. Moved getopt libary from utils to posix. Signed-off-by: Jakub Rzeszutko <jakub.rzeszutko@nordicsemi.no>

headers: Refactor kernel and arch headers. This commit refactors kernel and arch headers to establish a boundary between private and public interface headers. The refactoring strategy used in this commit is detailed in the issue This commit introduces the following major changes: 1. Establish a clear boundary between private and public headers by removing "kernel/include" and "arch/*/include" from the global include paths. Ideally, only kernel/ and arch/*/ source files should reference the headers in these directories. If these headers must be used by a component, these include paths shall be manually added to the CMakeLists.txt file of the component. This is intended to discourage applications from including private kernel and arch headers either knowingly and unknowingly. - kernel/include/ (PRIVATE) This directory contains the private headers that provide private kernel definitions which should not be visible outside the kernel and arch source code. All public kernel definitions must be added to an appropriate header located under include/. - arch/*/include/ (PRIVATE) This directory contains the private headers that provide private architecture-specific definitions which should not be visible outside the arch and kernel source code. All public architecture- specific definitions must be added to an appropriate header located under include/arch/*/. - include/ AND include/sys/ (PUBLIC) This directory contains the public headers that provide public kernel definitions which can be referenced by both kernel and application code. - include/arch/*/ (PUBLIC) This directory contains the public headers that provide public architecture-specific definitions which can be referenced by both kernel and application code. 2. Split arch_interface.h into "kernel-to-arch interface" and "public arch interface" divisions. - kernel/include/kernel_arch_interface.h * provides private "kernel-to-arch interface" definition. * includes arch/*/include/kernel_arch_func.h to ensure that the interface function implementations are always available. * includes sys/arch_interface.h so that public arch interface definitions are automatically included when including this file. - arch/*/include/kernel_arch_func.h * provides architecture-specific "kernel-to-arch interface" implementation. * only the functions that will be used in kernel and arch source files are defined here. - include/sys/arch_interface.h * provides "public arch interface" definition. * includes include/arch/arch_inlines.h to ensure that the architecture-specific public inline interface function implementations are always available. - include/arch/arch_inlines.h * includes architecture-specific arch_inlines.h in include/arch/*/arch_inline.h. - include/arch/*/arch_inline.h * provides architecture-specific "public arch interface" inline function implementation. * supersedes include/sys/arch_inline.h. 3. Refactor kernel and the existing architecture implementations. - Remove circular dependency of kernel and arch headers. The following general rules should be observed: * Never include any private headers from public headers * Never include kernel_internal.h in kernel_arch_data.h * Always include kernel_arch_data.h from kernel_arch_func.h * Never include kernel.h from kernel_struct.h either directly or indirectly. Only add the kernel structures that must be referenced from public arch headers in this file. - Relocate syscall_handler.h to include/ so it can be used in the public code. This is necessary because many user-mode public codes reference the functions defined in this header. - Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is necessary to provide architecture-specific thread definition for 'struct k_thread' in kernel.h. - Remove any private header dependencies from public headers using the following methods: * If dependency is not required, simply omit * If dependency is required, - Relocate a portion of the required dependencies from the private header to an appropriate public header OR - Relocate the required private header to make it public.
