It is internal only, not a documented API.

SubprocessError and TimeoutError in its list of exported names for the
users wild enough to use "from subprocess import *".

MAXFD, mswindows and list2cmdline should be dealt with (renamed or
moved) in separate commits.

again if the first call to connect() raises an InterruptedError.

When the C function connect() fails with EINTR, the connection runs in
background. We have to wait until the socket becomes writable to be notified
when the connection succeed or fails.

time bytes are received or sent. The socket timeout is now the maximum total
duration of the method.

This change fixes a denial of service if the application is regulary
interrupted by a signal and the signal handler does not raise an exception.

Call internal_select() with a timeout of 0 second, not a timeout of -1 second
(blocking)!

each time data is sent successfuly. The socket timeout is now the maximum total
duration to send all data.

Use _PyTime_FromSeconds() to initialize the default socket timeout to -1
second, instead of -1 nanosecond which causes rounding issues in
internal_select().

orderable and non-orderable elements no longer depends on iteration order of
set or dict.

This changeset does two things: introduces a new RemoteDisconnected exception
(that subclasses ConnectionResetError and BadStatusLine) so that a remote
server disconnection can be detected by client code (and provides a better
error message for debugging purposes), and ensures that the client socket is
closed if a ConnectionError happens, so that the automatic re-connection code
can work if the application handles the error and continues on.

Tests are added that confirm that a connection is re-used or not re-used
as appropriate to the various combinations of protocol version and headers.
