* Take re pos/endpos as signed integers
Negative values clamp to 0, and values beyond Py_ssize_t raise
OverflowError.

* Port the remaining runtime fixes from #7993
- bytearray: keep the buffer exported while converting the needle of
find/count/index/rfind/rindex/__contains__/split/rsplit and the hex
separator, so resizing from there raises BufferError
- str(): report non-str encoding/errors as "str() argument 'X' must be
str, not T", and check argument counts and name/position duplicates
for keyword calls
- _json.scanstring: take end as a signed integer and raise ValueError
when it is out of bounds
- lzma: reject filter specs with keys the filter does not take
- mmap: raise ValueError when growing a shared anonymous mapping on
Linux/NetBSD
- _sqlite3: check that the backup progress argument is callable
- Remove the expectedFailure markers of the tests these fix

* Reject arguments given by name and position in FuncArgs::bind_for
bind_for reports a keyword that fills a parameter already given by
position before other binding errors, using the parameter list of the
FromArgs type. getargs shares the message, str() drops its own check,
and blake2b/blake2s name themselves in binding errors.

This directory contains all of the Python files that make up the standard
library for RustPython.
Most of these files are copied over from the CPython repository (the 3.7
branch), with slight modifications to allow them to work under RustPython. The
current goal is to complete the standard library with as few modifications as
possible. Current modifications are just temporary workarounds for bugs/missing
feature within the RustPython implementation.
The first big module we are targeting is unittest, so we can leverage the
CPython test suite.
