Summary: The type timespec is unconditionally used in __threading_support. Since the C library is only required to provide it in C11, this might cause problems for platforms with external thread porting layer (i.e. when _LIBCPP_HAS_THREAD_API_EXTERNAL is defined) with pre-C11 C libraries. In our downstream port of libc++ we used to provide a definition of timespec in __external_threading, but this solution is not ideal because timespec is not a reserved name. This patch renames timespec into __libcpp_timespec_t in the thread-related parts of libc++. For all cases except external threading this type is an alias for ::timespec (and no functional changes are intended). In case of external threading it is expected that the __external_threading header will either provide a similar typedef (if timespec is available in the vendor's C library) or provide a definition of __libcpp_timespec_t compatible with POSIX timespec.
