[issue25318] Add _PyBytesWriter API to optimize Unicode encoders

[STINNER Victor]

STINNER Victor added the comment:

Buildbots still like this new API :-) (no test failure recently)

I reworked the API a little bit to make its usage simpler in Unicode encoders. I started to open new issues to using this new API in more functions producing byte strings.

I consider that this issue can now be closed. I'm happy, the API looks good to me and the modified code is faster.

----------
resolution:  -> fixed
status: open -> closed
