Disable interrupts whilst checking for keys in OS_ReadC / INKEY

This ensures that on exit from OS_ReadC / INKEY either a character is returned or the input buffer is empty, and that Portable_Idle is only called when the input buffer is empty.

This avoids a 10 microsecond delay and relying on timer interrupts to make progress and allows reliably waiting for input and another event by:

Disable Interrupts
Repeat
  Call INKEY(0), exit loop if key pressed
  Check other event, exit loop if key pressed
  Call Portable_Idle
