libstdc++: Define <stacktrace> header for C++23 Add the <stacktrace> header and a new libstdc++_libbacktrace.a library that provides the implementation. For now, the new library is only built if --enable-libstdcxx-backtrace=yes is used. As with the Filesystem TS, the new library is only provided as a static archive. libstdc++-v3/ChangeLog: * acinclude.m4 (GLIBCXX_ENABLE_BACKTRACE): New macro. * configure.ac: Use GLIBCXX_ENABLE_BACKTRACE. * include/Makefile.am: Add new header. * include/Makefile.in: Regenerate. * include/std/stacktrace: New header. * include/std/version (__cpp_lib_stacktrace): Define. * Makefile.in: Regenerate. * config.h.in: Regenerate. * configure: Regenerate. * doc/Makefile.in: Regenerate. * libsupc++/Makefile.in: Regenerate. * po/Makefile.in: Regenerate. * python/Makefile.in: Regenerate. * src/Makefile.am: Regenerate. * src/Makefile.in: Regenerate. * src/c++11/Makefile.in: Regenerate. * src/c++17/Makefile.in: Regenerate. * src/c++20/Makefile.in: Regenerate. * src/c++98/Makefile.in: Regenerate. * src/filesystem/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. * src/libbacktrace/Makefile.am: New file. * src/libbacktrace/Makefile.in: New file. * src/libbacktrace/backtrace-rename.h: New file. * src/libbacktrace/backtrace-supported.h.in: New file. * src/libbacktrace/config.h.in: New file. * testsuite/lib/libstdc++.exp (check_effective_target_stacktrace): New proc. * testsuite/20_util/stacktrace/entry.cc: New test. * testsuite/20_util/stacktrace/synopsis.cc: New test. * testsuite/20_util/stacktrace/version.cc: New test.
