PythonCore, but extensions may want to use some of
the routines not included. Fixes a bug reported by
Tom Loredo.

Fixes problem with not detecting UTF-8 errors.

- Don't scan for cmd-. unless in the foreground
- Scan before switching out to other processes, not after
- don't scan if SchedParams.check_interrupt is false (!)
  - But: do scan if we're blocked on I/O

One problem remains: in the last case KeyboardInterrupt is raised
too late.

supports the single-segment readable buffer interface.

Add documentation for this and other PyObject_XXXBuffer() calls.

socket.gaierror. :( This allows test_socket to pass on a RH6.1-ish
Linux system.

Easy enough to catch assignment in the compiler.  The perverse user
can still change the value of __debug__, but that may be the least he
can do.

message for bad mode argument -- so that it doesn't fail on Windows.

It's hack.  We know that errno is set to 0 in this case on Windows, so
check for that specifically.

strptime() -- I'm too lazy to code it otherwise.

object, so the "Metroworks only" section should not decref it in case
of error (the caller is responsible for decref'ing in case of error --
and does).

rfc822.py.  The old rfc822.formatdate() produced date strings using
obsolete syntax.  The new version produces the preferred RFC 2822
dates.

Also, an optional argument `localtime' is added, which if true,
produces a date relative to the local timezone, with daylight savings
time properly taken into account.

Fix contributed by Jeffrey C. Ollie.

I haven't tested the fix because the situation is non-trivial to
reproduce.

The basic solution is to get rid of the __current_realm attribute of
authentication handlers.  Instead, prevent infinite retries by
checking for the presence of an Authenticate: header in the request
object that exactly matches the Authenticate: header that would be
added.

The problem prevent authentication from working correctly in the
presence of retries.

Ollie mentioned that digest authentication has the same problem and I
applied the same solution there.

Fix by Neil Schemenauer.  Visit the Subscript node when trying to find
the operation for a statement.

XXX Not sure if there are other nodes that should be visited.

If fopen() fails with EINVAL it means that the mode argument is
invalid.  Return the mode in the error message instead of the
filename.

other platforms that have funny ideas about whether addresses of
functions in dlls are compile-time constants.

Lannert.  Added descriptions of HTTP_PORT and HTTPS_PORT.
