* csv: reject reentrant reader advancement
Snapshot the reader generation before calling the input iterator. If a nested
call completes a record and advances the same reader, reject the outer call
with csv.Error instead of continuing with stale parser state.
Increment the generation on each successful record path, matching CPython's
handling of the existing reentrant-reader regression. Enable that test by
removing its expectedFailure marker.

* csv: invalidate outer reads after reentry
Advance the reader generation immediately after the reentrancy check, before
validating or parsing the returned input item. This invalidates the outer call
even when a nested read later fails validation or parsing.
Remove the per-return generation updates now that the common path advances it
exactly once.

* csv: generation type conversion(usize to u64)
On 32-bit targets (like WebAssembly, which RustPython supports), usize is 32-bit.
Csv with over 32-bit rows can raise panic on these platform.
type conversion from usize to u64.
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.
