Remove more vestiges of the thread support
...
Also, remove a required function from console interface. Now a plugin
is only responsible for their thread behavior and never responsible
for the consoleserver mechanism requirement for helping user session
do polling IO. This is additionally great because it means the
coordination is contained to each session object and many client connections
are not causing multiple calls to iterate the wait loop.

Fix cval assignment exception
...
For SOL sessions, the queue could be touched without anything in ipmiq.
Have cval be set to something benign in those cases to avoid a trace in
debug.

Fix race condition on console connect
...
When data was coming in during logon, it was possible for
the handler to be called before rcpts member was initialized.
Correct by initializing rcpts prior to taking any other action.

Have ipmi plugin print out traceback data when exceptions would be encountered
...
For now, see the errors even as they are tolerated. This allows problems to be fixed
as best as possible. Ultimately, this will be logged.

Fix ipmi events if pyghmi spins in an eventloop
...
If circumstances inside pyghmi cause it to be looping in
an event loop, confluent was getting work done, but
the code to wake up the eventlet greenthreads wouldn't get tickled.
Address this by also waking up waiters in the function that is
invited to the pyghmi event loop party.

Better isolate faults in the ipmi plugin
...
Previously, one ipmi failure would tank all consoles and commands.
Now, at least console failures are isolated.
Next stop is to isolate command failures, then fix up session recovery.

Convert wsgi function to be generator
...
Since wsgi function returns iterable, it turns out to be easy to do it this way.
For now, hardcode json dumps, two things:
1: call out to module supporting HTML and JSON interpretation
2: in both cases, a header and footer must sandwich the responses in http
In socketapi, responses will come back without a container, but http
does not afford us such luxury. Create a containing json structure.
On first iteration, do not prepend with ,. prepend with , all other times.
