msg: Add bb.warnonce() and bb.erroronce() log methods

This adds a log level and logging function call to use it where the
warning or error will only be displayed once, regardless of how many
times the message is logged.

This has to be done either in the cooker or on the UI side. I've opted
for the UI side since display control is really a UI issue but it uses
a common library filter function to enable it which can be reused
elsewhere.

The knotty message displayed as the build summary is tweaked to
make sense when the numbers won't match since it will still count
the number of times it was logged and this is probably helpful
for debugging in some cases so I've deliberately left it that way.
