6bd525b656 Optimize error handlers of ASCII and Latin1 encoders when the replacement 
string is pure ASCII: use _PyBytesWriter_WriteBytes(), don't check individual
character.

Cleanup unicode_encode_ucs1():

* Rename repunicode to rep
* Clear rep object on error
* Factorize code between bytes and unicode path

e7bf86cd7d Optimize backslashreplace error handler 
Issue #25318: Optimize backslashreplace and xmlcharrefreplace error handlers in
UTF-8 encoder. Optimize also backslashreplace error handler for ASCII and
Latin1 encoders.

Use the new _PyBytesWriter API to optimize these error handlers for the
encoders. It avoids to create an exception and call the slow implementation of
the error handler.

fdfbf78114 Issue #25318: Add _PyBytesWriter API 
Add a new private API to optimize Unicode encoders. It uses a small buffer
allocated on the stack and supports overallocation.

Use _PyBytesWriter API for UCS1 (ASCII and Latin1) and UTF-8 encoders. Enable
overallocation for the UTF-8 encoder with error handlers.

unicode_encode_ucs1(): initialize collend to collstart+1 to not check the
current character twice, we already know that it is not ASCII.

29e68edbf4 Issue #24848: Fixed bugs in UTF-7 decoding of misformed data: 
1. Non-ASCII bytes were accepted after shift sequence.
2. A low surrogate could be emitted in case of error in high surrogate.
3. In some circumstances the '\xfd' character was produced instead of the
replacement character '\ufffd' (due to a bug in _PyUnicodeWriter).

ac2ef65c32 Make the unicode equality test an external function rather than in-lining it. 
The real benefit of the unicode specialized function comes from
bypassing the overhead of PyObject_RichCompareBool() and not
from being in-lined (especially since there was almost no shared
data between the caller and callee).  Also, the in-lining was
having a negative effect on code generation for the callee.
