This patch creates a global function __syncbuf_get_mutex, gated by
_GLIBCXX_HAS_GTHREADS, replacing a static instantiated member
_S_get_mutex used in syncbuf<> construction, and makes the global
symbol visible. A static local table of 16 mutexes is shared among
all specializations of syncbuf<>, chosen on construction by a hash
of the wrapped streambuf's address.
It detaches the implementation of _S_get_mutex from the C++20 ABI.
libstdc++-v3/ChangeLog:
* include/std/syncstream: (syncbuf<>::__mutex) Remove _S_get_mutex,
use extern function instead.
* src/c++20/syncbuf.cc: Define global __syncbuf_get_mutex.
* src/c++20/Makefile.am: Mention syncbuf.cc.
* src/c++20/Makefile.in: Regenerate.
* config/abi/pre/gnu.ver: Mention mangled __syncbuf_get_mutex.
