[New-bugs-announce] [issue23001] Accept mutable bytes-like objects

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Some builtins accept only read-only bytes-like objects (PyArg_Parse format codes "s#", "z#", "y", and "y#"). Proposed patch makes them accepting also mutable bytes-like objects such as bytearray.

I'm not sure that all these changes are useful, but in some cases this can get rid of copying binary data created in bytearray (e.g. read by readinto()).
