938d44d59c Issue #14605: Expose importlib.abc.FileLoader and 
importlib.machinery.(FileFinder, SourceFileLoader,
_SourcelessFileLoader, ExtensionFileLoader).

This exposes all of importlib's mechanisms that will become public on
the sys module.

5c903e6ee1 Issue #13959: Continue to try to accomodate altsep in importlib by not 
ignoring altsep if it already exists on a path when doing a join.

cf649958f7 Revert to os.path.join() semantics for path manipulation in importlib 
which is different than what imp.cache_from_source() operates on.

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.

f0434e647a Issue #14599: Generalize a test for ImportError.path and add support

This should fix the remaining importlib test failure on Windows.
Support in AIX and HP-UX will be in a separate checkin.

b0b224233e Issue #14385: Support other types than dict for __builtins__ 
It is now possible to use a custom type for the __builtins__ namespace, instead
of a dict. It can be used for sandboxing for example.  Raise also a NameError
instead of ImportError if __build_class__ name if not found in __builtins__.

94c001b503 Fix email post-commit review comments. 
Add INCREFs, fix args->kwargs, and a second args==NULL check was removed,
left over from a merger with another function. Instead, checking msg==NULL
does what that used to do in a roundabout way.

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.

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.
