56aae8f304 Issue #17633: Improve support for namespace packages with zipimport. 
Previously zipimport mistakenly limited namespace support to only the
top-level of the zipfile when it should have supported an arbitrary
depth.

Thanks to Phil Connel for the bug report and initial patch and Mike
Romberg for the final patch.

f299abdafa Issue #23731: Implement PEP 488. 
The concept of .pyo files no longer exists. Now .pyc files have an
optional `opt-` tag which specifies if any extra optimizations beyond
the peepholer were applied.

2e385e2592 Fixes issue #19081: When a zipimport .zip file in sys.path being imported from 
is modified during the lifetime of the Python process after zipimport has
already cached the zip's table of contents we detect this and recover
rather than read bad data from the .zip (causing odd import errors).

cc6abd56b8 Fix zipimport.c's read_directory() to use appropriate types for the values 
being read from the header vs the values being used by fseek and ftell
(Py_ssize_t for those).  Updates the Py_BuildValue format string to match
(including several existing wrong 'i's that should have been 'l's).

ab32066e65 Fix zip_import.c's read_directory() to use appropriate types for the values 
being read from the header vs the values being used by fseek and ftell
(Py_ssize_t for those) and how they are computed.  Py_ssize_t is used for
actual file offsets so that files greater than 2gigs could be supported.
Updates the Py_BuildValue format string to match (including several existing
wrong 'i's that should have been 'l's).
