read or readall methods no longer lose data when an underlying read
system call is interrupted within an io module object. IOError is no
longer raised due to a read system call returning EINTR from within
these methods.
This is a backport of changeset 781b95159954 from 3.2.
The earlier 2.7 changeset 67dc99a989cd already fixed this for the
builtin python 2.x file object.
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.
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).

In open(), only set the buffer size from st.st_blksize when it is greater
than 1. This matches the pure Python implementation in _pyio and should
fix a couple of failures on the NetBSD buildbot.
