Kristjan Valur Jonsson 85634d7a2e Issue #14909: A number of places were using PyMem_Realloc() apis and
PyObject_GC_Resize() with incorrect error handling.  In case of errors,
the original object would be leaked.  This checkin fixes those cases.

Victor Stinner d3f0882dfb 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.

   the maximum character (whereas we already know it, it is just the character

   stderr.
 * Fix time.strftime() (if wcsftime() is missing): decode strftime() result

 * Remove _PyUnicode_DIRTY(): no need to reset the hash anymore, because if the
   hash has already been computed, you cannot modify a string inplace anymore
 * PyUnicode_Concat() checks for integer overflow

Victor Stinner c3cec7868b Add asciilib: similar to ucs1, ucs2 and ucs4 library, but specialized to ASCII
ucs1, ucs2 and ucs4 libraries have to scan created substring to find the
maximum character, whereas it is not need to ASCII strings. Because ASCII
strings are common, it is useful to optimize ASCII.

Victor Stinner ce5faf673e unicodeobject.c doesn't make output strings ready in debug mode
Try to only create non ready strings in debug mode to ensure that all functions
(not only in unicodeobject.c, everywhere) make input strings ready.

Victor Stinner c80d6d20d5 Speedup str[a🅱️step] for step != 1
Try to stop the scanner of the maximum character before the end using a limit
depending on the kind (e.g. 256 for PyUnicode_2BYTE_KIND).

Victor Stinner ae86485517 Speedup find_maxchar_surrogates() for 32-bit wchar_t
If we have at least one character in U+10000-U+10FFFF, we know that we must use
PyUnicode_4BYTE_KIND kind.

Victor Stinner b9275c104e Speedup str[a:b] and PyUnicode_FromKindAndData
* str[a:b] doesn't scan the string for the maximum character if the string
   is ascii only
 * PyUnicode_FromKindAndData() stops if we are sure that we cannot use a
   shorter character type. For example, _PyUnicode_FromUCS1() stops if we
   have at least one character in range U+0080-U+00FF

Victor Stinner 702c734395 Speedup the ASCII decoder
It is faster for long string and a little bit faster for short strings,
benchmark on Linux 32 bits, Intel Core i5 @ 3.33GHz:

./python -m timeit 'x=b"a"' 'x.decode("ascii")'
./python -m timeit 'x=b"x"*80' 'x.decode("ascii")'
./python -m timeit 'x=b"abc"*4096' 'x.decode("ascii")'

length |   before   | after

     1 | 0.234 usec | 0.229 usec
    80 | 0.381 usec | 0.357 usec
