This moves the "classic" contents of <chrono> to a new header, so that <future>, <thread> etc. can get use durations and clocks without calendar types, time zones, and chrono I/O. libstdc++-v3/ChangeLog: * include/Makefile.am: Add new header. * include/Makefile.in: Regenerate. * include/std/chrono (duration, time_point, system_clock) (steady_clock, high_resolution_clock, chrono_literals, sys_time) (file_clock, file_time): Move to ... * include/bits/chrono.h: New file. * include/bits/atomic_futex.h: Include new header instead of <chrono>. * include/bits/atomic_timed_wait.h: Likewise. * include/bits/fs_fwd.h: Likewise. * include/bits/semaphore_base.h: Likewise. * include/bits/this_thread_sleep.h: Likewise. * include/bits/unique_lock.h: Likewise. * include/experimental/bits/fs_fwd.h: Likewise. * include/experimental/chrono: Likewise. * include/experimental/io_context: Likewise. * include/experimental/netfwd: Likewise. * include/experimental/timer: Likewise. * include/std/condition_variable: Likewise. * include/std/mutex: Likewise. * include/std/shared_mutex: Likewise.
