bitbake: server/process: Improve exception and idle function logging

Browse Source 
Currently if the idle functions loop suffers a traceback, it is
silently dropped and there is no log message to say what happened.
This change at least means the traceback is in the cooker log, making
some debugging possible.

Add some logging to show when handlers are added/removed to allow
a better idea of what the server code is doing from the server log
file.

(Bitbake rev: 9cf3102dc36513124fe5ead2f1e448b51833b6ac)
