- don't try anything unless something really lives in sys.modules by
that name

that
When Stream.connect() fails, have it just use on_disconnect(). Now there
is a single disconnect cleanup path.
Remove cutpasted DiagLogStream setup/destruction, and move it into the
base class (temporarily), and only manage the lifetime of its underlying
FD via Side.close(). This cures another EBADF failure.
The user@host prefix in new-style OpenSSH messages unfortunately takes
the host part from ~/.ssh/config and friends. There is no way to know
which hostname will appear in this string without parsing the OpenSSH
config, nor which username will appear.
Instead just regex it.
Add SSH stub modes to print the new/old errors and add some simple
tests.
This extends the work done in b9112a9cbb
* ansible: use unicode_literals everywhere since it only needs to be
compatible back to 2.6.
* compat/collections.py: delete this entirely and rip out the parts of
functools that require it.
* Introduce serializable Kwargs dict subclass that translates keys to
Unicode on instantiation.
* enable_debug_logging() must set _v/_vv globals.
* cStringIO does not exist in 3.x.
* Treat IOLogger and LogForwarder input as latin-1.
* Avoid ResourceWarnings in first stage by explicitly closing fps.
* Fix preamble_size.py syntax errors.
See source comment. This behaviour always existed, but it now seems to
be triggered since we started draining the master side input buffer,
which someone was prolonging the life of the PTY.
