This reverts commit ea251806b8.
Keep "assert(interned == NULL);" in _PyUnicode_Fini(), but only for
the main interpreter.
Keep _PyUnicode_ClearInterned() changes avoiding the creation of a
temporary Python list object.
gvfs-open was deprecated in 2015 and removed in 2018, but its replacement,
gio(1), is not available in Ubuntu 16.04, which is apparently still
supported by CPython upstream even though it is considered to be EOL by
Ubuntu developers.

x_mul()'s squaring code can do some redundant and/or useless
work at the end of each digit pass. A more careful analysis
of worst-case carries at various digit positions allows
making that code leaner.
This change solves two problems encountered by users of the macOS Python Launcher app on recent macOS releases (10.14+):
- The launcher app was no longer able to launch the macOS Terminal.app to run a script.
- Even if Terminal.app was already launched, the launcher app was unable to send an Apple Event to Terminal.app to open and run Python with the desired .py file.
* bpo-46218: Change long_pow() to sliding window algorithm
The primary motivation is to eliminate long_pow's reliance on that the number of bits in a long "digit" is a multiple of 5. Now it no longer cares how many bits are in a digit.
But the sliding window approach also allows cutting the precomputed table of small powers in half, which reduces initialization overhead enough that the approach pays off for smaller exponents too. Depending on exponent bit patterns, a sliding window may also be able to save some bigint multiplies (sometimes when at least 5 consecutive exponent bits are 0, regardless of their starting bit position modulo 5).
Note: boosting the window width to 6 didn't work well overall. It give marginal speed improvements for huge exponents, but the increased overhead (the small-power table needs twice as many entries) made it a loss for smaller exponents.

The idea is to ensure that module `xml.parsers.expat.errors`
contains all known error codes and messages,
even when CPython is compiled or run with an outdated version of libexpat.
