nptl: Add C11 threads call_once functions
This patch adds the call_* definitions from C11 threads (ISO/IEC 9899:2011), more specifically call_once and required types. 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, 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. [BZ #14092] * 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_2.28]: Add call_once symbol. * nptl/call_once.c: New file. * sysdeps/nptl/threads.h (ONCE_FLAG_INIT): New define. (once_flag): New type. (call_once): New prototype.
