Mostly of the definitions are composed based on POSIX conterparts, such as thrd_t (using pthread_t). For thrd_* function internally direct POSIX pthread call are used with the exceptions: 1. thrd_start uses pthread_create internal implementation, but changes how to actually calls the start routine. This is due the difference in signature between POSIX and C11, where former return a 'void *' and latter 'int'. To avoid calling convention issues due 'void *' to int cast, routines from C11 threads are started slight different than default pthread one. Explicit cast to expected return are used internally on pthread_create and the result is stored back to void also with an explicit cast. 2. thrd_sleep uses nanosleep internal direct syscall to avoid clobbering errno, to handle expected standard return codes, and to avoid making the call a POSIX cancellation entrypoint. 3. thrd_yield also uses internal direct syscall to avoid errno clobbering. Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, tile{pro,gx}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu. * conform/Makefile (conformtest-headers-ISO11): Add threads.h.

Mostly of the definitions are composed based on POSIX conterparts, and mtx_t is also based on internal pthread fields, but with a distinct internal layout to avoid possible issues with code interchange (such as trying to pass POSIX structure on C11 functions and to avoid inclusion of pthread.h). The idea is to make possible to share POSIX internal implementations for mostly of the code (and making adjustment only when required). Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, tile{pro,gx}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu. * conform/data/threads.h-data (mtx_plain): New constant.

Mostly of the definitions are composed based on POSIX conterparts,including once_flag (pthread_once_t). The idea is to make possible to share POSIX internal implementations for mostly of the code (and making adjustment only when required). Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, tile{pro,gx}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu. * conform/data/threads.h-data (ONCE_FLAG_INIT): New macro. (once_flag): New type. (call_once): New function. * nptl/Makefile (libpthread-routines): Add call_once object. * nptl/Versions (libphread) [GLIBC_2.27]: Add call_once symbol. * nptl/call_once.c: New file. * sysdeps/nptl/threads.h (ONCE_FLAG_INIT): New define.

Mostly of the definitions are composed based on POSIX conterparts, and cnd_t is also based on internal pthreads fields, but with distinct internal layout to avoid possible issues with code interchange (such as trying to pass POSIX structure on C11 functions and to avoid inclusion of pthread.h). The idea is to make it possible to share POSIX internal implementation for mostly of the code making adjust where only required. Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, tile{pro,gx}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu. * conform/data/threads.h-data (cnd_t): New type. (cnd_init): New function.

Mostly of the definitions are composed based on POSIX conterparts, including tss_t (pthread_key_t). Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, tile{pro,gx}-linux-gnu, and x86_64-linux-gnu). Also ran a full check on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabhf, and powerpc64le-linux-gnu. * conform/data/threads.h-data (thread_local): New macro.
