Antoine Pitrou 5aa7df320f Issue #13322: Fix BufferedWriter.write() to ensure that BlockingIOError is
raised when the wrapped raw file is non-blocking and the write would block.
Previous code assumed that the raw write() would raise BlockingIOError, but
RawIOBase.write() is defined to returned None when the call would block.
Patch by sbt.

would be finalized after the reference to its underlying BufferedRWPair's
writer got cleared by the GC.

Antoine Pitrou ee46a7bf9c Issue #12062: In the `io` module, fix a flushing bug when doing a certain
type of I/O sequence on a file opened in read+write mode (namely: reading,
seeking a bit forward, writing, then seeking before the previous write but
still within buffered data, and writing again).

Benjamin Peterson ddd392cbb9 accept None as the same as having passed no argument in file types #7349
This is for consistency with imitation file objects like StringIO and BytesIO.

This commit also adds a few tests, where they were lacking for concerned
methods.

Mark Dickinson 3ddb52717f Roll back ill-considered attempts to fix printf specifier mismatch for off_t.
The sensible solution seems to be to implement %lld for PyString_FromFormat(V)

Antoine Pitrou 20e1f932fa Issue #6629: Fix a data corruption issue in the new `io` package, which could
occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or
"wb+" mode) after having buffered a certain amount of data for reading. This
bug was not present in the pure Python implementation.

Yes, this is a serious issue.
