strings are not convincing. For UCS2 (16-bit wchar_t type), use a dummy loop

wchar_t.

Fix the internals of our hash functions to used unsigned values during hash
...
computation as the overflow behavior of signed integers is undefined.
NOTE: This change is smaller compared to 3.2 as much of this cleanup had
already been done. I added the comment that my change in 3.2 added so that the
code would match up. Otherwise this just adds or synchronizes appropriate UL
designations on some constants to be pedantic.
In practice we require compiling everything with -fwrapv which forces overflow
to be defined as twos compliment but this keeps the code cleaner for checkers
or in the case where someone has compiled it without -fwrapv or their
compiler's equivalent. We could work to get rid of the -fwrapv requirement
in 3.4 but that requires more planning.
Found by Clang trunk's Undefined Behavior Sanitizer (UBSan).
Cleanup only - no functionality or hash values change.

Issue #16147 : Rewrite PyUnicode_FromFormatV() to use _PyUnicodeWriter API
...
* Simplify the code: replace 4 steps with one unique step using the
_PyUnicodeWriter API. PyUnicode_Format() has the same design. It avoids to
store intermediate results which require to allocate an array of pointers on
the heap.
* Use the _PyUnicodeWriter API for speed (and its convinient API):
overallocate the buffer to reduce the number of "realloc()"
* Implement "width" and "precision" in Python, don't rely on sprintf(). It
avoids to need of a temporary buffer allocated on the heap: only use a small
buffer allocated in the stack.
* Add _PyUnicodeWriter_WriteCstr() function
* Split PyUnicode_FromFormatV() into two functions: add
unicode_fromformat_arg().
* Inline parse_format_flags(): the format of an argument is now only parsed
once, it's no more needed to have a subfunction.
* Optimize PyUnicode_FromFormatV() for characters between two "%" arguments:
search the next "%" and copy the substring in one chunk, instead of copying
character per character.

Issue #14744 : Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args)

* Formatting string, int, float and complex use the _PyUnicodeWriter API. It
avoids a temporary buffer in most cases.
* Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just
keep a reference to the string if the output is only composed of one string
* Disable overallocation when formatting the last argument of str%args and
str.format(args)
* Overallocation allocates at least 100 characters: add min_length attribute
to the _PyUnicodeWriter structure
* Add new private functions: _PyUnicode_FastCopyCharacters(),
_PyUnicode_FastFill() and _PyUnicode_FromASCII()
The speed up is around 20% in average.

Merge from 3.1: Issue #13703 : add a way to randomize the hash values of basic types (str, bytes, datetime)
...
in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated.
The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.

This excludes the Modules/ tree (datetime and expat both have a copy
for their own purposes with no need for it to be the same).

Add PyUnicode_DecodeLocaleAndSize() and PyUnicode_DecodeLocale()
...
* PyUnicode_DecodeLocaleAndSize() and PyUnicode_DecodeLocale() decode a string
from the current locale encoding
* _Py_char2wchar() writes an "error code" in the size argument to indicate
if the function failed because of memory allocation failure or because of a
decoding error. The function doesn't write the error message directly to
stderr.
* Fix time.strftime() (if wcsftime() is missing): decode strftime() result
from the current locale encoding, not from the filesystem encoding.
