Removed repeated checking of bus_request_line_. It's now checked only after each outward perform_machine_cycle.

Merge pull request #214 from TomHarte/Sleeper
Experimentally introduces the concept of a 'sleeper' — a component that will volunteer to be unclocked for a period

Worked logic all the way down to the CPC. If the 8272 announces that it is asleep, it is now no longer clocked. Also very slightly cut down on IRQ line chatter to the Z80.

Sketched out a protocol designed to save processing time on anything that may sleep — probably just disk controllers for now but one can easily imagine it being applicable to printers, and possibly sound chips with suitable changes in guarantee for sound packet receivers.

Having spotted that I was using my single-character loop counter names incorrectly (quelle surprise!), got a bit more explicit. Also flattened into a single loop so that I can break rather than returning.

Step one towards cutting much of this cost: build only the table that's appropriate for the current mode, and at least declare when a more minimal change would be sufficient.

Ideally I would be able to kill this multiplier, as it could easily be derived at runtime. But, for now, just turned it up so that the analysis-oriented parser is better at parsing different bit rates.
