Issue #19619 : Blacklist non-text codecs in method API
...
str.encode, bytes.decode and bytearray.decode now use an
internal API to throw LookupError for known non-text encodings,
rather than attempting the encoding or decoding operation and
then throwing a TypeError for an unexpected output type.
The latter mechanism remains in place for third party non-text
encodings.

Close #19568 : Fix bytearray_setslice_linear(), fix handling of

PyByteArray_Resize() failure: leave the bytearray object in an consistent state.
If growth < 0, handling the memory allocation failure is tricky here because
the bytearray object has already been modified. If lo != 0, the operation is
completed, but a MemoryError is still raised and the memory block is not
shrinked. If lo == 0, the bytearray is restored in its previous state and a
MemoryError is raised.

The setobject freelist was consuming memory but not providing much value.
Even when a freelisted setobject was available, most of the setobject

a memset(). This meant that the custom freelisting scheme for sets was
providing almost no incremental benefit over the default Python freelist
scheme used by _PyObject_Malloc() in Objects/obmalloc.c.

Instead of XORed indicies, switch to a hybrid of linear probing and open addressing.
...
Modern processors tend to make consecutive memory accesses cheaper than
random probes into memory.
Small sets can fit into L1 cache, so they get less benefit. But they do
come out ahead because the consecutive probes don't probe the same key
more than once and because the randomization step occurs less frequently
(or not at all).
For the open addressing step, putting the perturb shift before the index
calculation gets the upper bits into play sooner.
