a BIT of 65C02 optimisations
...
Use BIT immediate instead of AND when reloading A is required
afterwards.
Add an fread unit test as the optimisation touches fread.
Sprinkle a few zero page indexed while we're at it.

Added a special version of a function which uses an absolute addressing mode to access the zero page.
...
The PCEngine needs such operands to be redirected to RAM page $20 explicitly. Fixes #1482 ; fixes #1483 .

Use the new declarations from the zeropage include file. In interrupt handlers
...
that call C code, we don't need to save the register bank, because the C code
will save it, when needed.

ignored) that do not exist.
Added C99 modifiers z, j and t.
