Amazing, io-c is faster but also fixes many bugs!

In the io-c branch, read1() is now a member of BufferedIOBase.

New submission from HiroakiKawai ka...@apache.org:
The documentation says io.TextIOWrapper wraps io.BufferedIOBase raw
stream. In the code, io.TextIOWrapper.read(),
io.TextIOWrapper._read_chunk() calls buffer.read1() which seems
expecting buffer to be an instance of io.BufferedReader. I'm not
Antoine Pitrou pit...@free.fr added the comment:
Indeed, read1() is not documented as a standard method of either IOBase,
RawIOBase or BufferedIOBase. I suggest that it becomes a standard method
of IOBase, with a default implementation simply calling read(n).
It also means unbuffered stdio as

IOBase doesn't even define read(), though! I think we should make it
part of BufferIOBase.

Short example to reproduce the problem:
---
import io, os
fd = os.open(/etc/issue, os.O_RDONLY)
raw = open(fd, rb, buffering=0)
text = io.TextIOWrapper(raw, line_buffering=False)
print(text.read(1))

I don't understand the motivation of having two different methods
for raw streams: read1() and read(). I would prefer to have only a
method read() (because read is the most common name, whereas read1()
is only used on Python3),
