Hardware: separate monitor from keyboard/mouse devices

branlwyd commented 11 years ago

Refactor DebuggerFrame, InstructionDecoder, Operand value formatting to use a new ValueFormatter interface rather than using parameters to specify hex or dec. This would add flexibility if we wanted to add different numeric formats later, or if we add another debugger UI. 99dc35871f0f8cf2ba976ab25ef13ef057d3e0f1
~~The *Operand classes in cc.bran.bdcpu16.codegen are only ever intended to be used by Operand. Move these classes to be private internal classes to Operand.~~ 9470ecadddef3515293f6e4ddccf25ab6beac7c7
Refactor int Operand.wordsUsed() into boolean usesWord(). Every operand uses 0 or 1 words, so this is still sufficiently expressive; and many places in code make the assumption that every operand will consume 0 or 1 words, so making this change will cause the interface to match the existing assumptions. 9470ecadddef3515293f6e4ddccf25ab6beac7c7
Consider factoring the Keboard/Mouse device pieces apart from the Terminal (UI) piece, and allowing Keyboard/Mouse devices to be arbitrarily attached/detached from Terminals.

Renaming this since there is only one refactor left, and it's pretty big.
