This patch prevents tracebacks and instead logs exceptions
that may happen during event processing.

The registration of a remote UI event handler may fail
if the server cooker is currently in some certain states.
This may happen, for example, when a remote UI is started
very fast after the bitbake server is started, and the
server hadn't time to finish initial configuration parsing.
Rather than fail outright, we have the remote UI event retry
registration for five time at one-second intervals,
in the hope it will succeed.

When we use the XMLRPC client API to connect to a bitbake server,
we want to receive errors from the API instead of having the
API exiting without warning.
Thus the "bb.fatal" calls have been replaced with "bb.warn" calls,
and we re-raise the original exception for handling by the
original caller.
The bitbake starting script has been modified to properly test
for failures in calling the client API and handle them.
Additional error handling added in the client, as to prevent
fatal crashes.

Rather than passing featureset around various places where the data doesn't
really belong, run a command at connection time to set the appropriate
features. This is similar to what the process server does.

Implementing feature set selection that allows a client
to enable specific features in the server at connection time.
Only enabling of features is supported, as there is
no way to safely remove data loaded into the cooker.
Once enabled, a feature will remain enabled for the
life of the cooker.
Client-server connection now supports specifying the feature
set required by the client. This is implemented in the Process
server using a managed proxy list, so the server cooker
will now load dynamically needed features based on what client
connects to it.
In the XMLRPC server the feature set is requested by
using a parameter for registerUIHandler function.
This allows observer-only clients to also specify features
for the server.
The server code configuration now is completly separated
from the client code. All hardcoding of client knowledge is
removed from the server.
The extra_caches is removed as the client can now specify
the caches it needs using the feature. The UI modules
now need to specify the desired featureSet. HOB is modified
to conform to the featureSet specification.
The only feature available is CookerFeatures.HOB_EXTRA_CACHES
which forces loading the bb.cache_extra:HobRecipeInfo class.

I add an observer only mode for the knotty UI and
the XMLRPC server that will allow the UI to register
a callback with a server in order to receive events.
The observer-UI is able to send read-only commands to the
server, and also is able to register as an event handler.
Read-only commands are the commands that do not change
the state of the server and have been marked as such in
the command module.
The observer can switch to a full client if it calls addClient
at any time, and the server has no other client running.

There is a race where the registerEventHandler() server call may happen in
a different thread to the main UI, causing the main UI to see
httplib.CannotSendRequest exceptions.
This moves the call into the main thread, removing the init race and fixing
errors I was seeing with the xmlrpc backend.

In server/client split model, the client will bind to a specific address
and port. We need to pass the values to BitBakeServerConnection().

The change to Queue up events before the UI is spawned broke the xmlrpc
server because the uievent implementation of BBUIEventQueue expects pickled
strings for its queue_event() method.
This is because the RPC exposed event.send() method must accept pickled
strings, but for xmlrpc event.send() is just mapped to queue_event(). Work
around this by adding a send_event method which unpickles strings and hands
them off to queue_event() which can then be used for the remapping.

We now have ParseStarted, ParseProgress, and ParseCompleted. I think this
clarifies matters, and avoids sending all our statistics with every parse
progress event.

as glade is not imported by default and need that extra line,
pyflakes does not know...
