Brett Cannon 2657df4744 Issue #13959: Re-implement imp.get_suffixes() in Lib/imp.py. 
This introduces a new function, imp.extension_suffixes(), which is
currently undocumented. That is forthcoming once issue #14657 is
resolved and how to expose file suffixes is decided.

Larry Hastings 76ad59b7e8 Issue #14127: Add ns= parameter to utime, futimes, and lutimes. 
Removed futimens as it is now redundant.
Changed shutil.copystat to use st_atime_ns and st_mtime_ns from os.stat
and ns= parameter to utime--it once again preserves exact metadata on Linux!

Victor Stinner ec89539ccc Issue #14428, #14397: Implement the PEP 418

   QueryPerformanceCounter()
 * time.monotonic() uses CLOCK_HIGHRES if available
 * Add time.get_clock_info(), time.perf_counter() and time.process_time()

Brett Cannon efad00d520 Issue #14646: __import__() now sets __loader__ if need be. 
importlib.util.module_for_loader also will set __loader__ along with
__package__. This is in conjunction to a forthcoming update to PEP 302
which will make these two attributes required for loaders to set.

Brett Cannon e0d88a173c Issue #14605: Make explicit the entries on sys.path_hooks that used to 
be implicit.

Added a warning for when sys.path_hooks is found to be empty. Also
changed the meaning of None in sys.path_importer_cache to represent
trying sys.path_hooks again (an interpretation of previous semantics).
Also added a warning for when None was found.

The long-term goal is for None in sys.path_importer_cache to represent
the same as imp.NullImporter: no finder found for that sys.path entry.

the sys module.

Brett Cannon 24117a748b Issue #13959: Keep imp.get_magic() in C code, but cache in importlib 
for performance. While get_magic() could move to Lib/imp.py, having to
support PyImport_GetMagicNumber() would lead to equal, if not more, C
code than sticking with the status quo.

does what that used to do in a roundabout way.

Brett Cannon 8a1d04c643 Issue #13959: Simplify imp.reload() by relying on a module's 
__loader__.

Since import now sets __loader__ on all modules it creates and
imp.reload() already relied on the attribute for modules that import
didn't create, the only potential compatibility issue is if people
were deleting the attribute on modules and expecting imp.reload() to
continue to work.

importlib (privately) and then publicly exposed in imp.

Brett Cannon 881535b726 Issue #14582: Import returns the module returned by a loader instead 
of sys.modules when possible.

This is being done for two reasons. One is to gain a little bit of
performance by skipping an unnecessary dict lookup in sys.modules. But
the other (and main) reason is to be a little bit more clear in how
things should work from the perspective of import's interactions with
loaders. Otherwise loaders can easily forget to return the module even
though PEP 302 explicitly states they are expected to return the module
they loaded.

importlib._bootstrap is now frozen into Python/importlib.h and stored

code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().
