Subject: Make DLion BITBLT interruptable

Lisp Version: 

Description: It will not be possible to make DLion RS232 work with reasonable responsiveness until the BITBLT opcode (and any others of indefinite length) check for interrupts. BITBLT is the most important because it is the bottleneck in RS322 chat, and not getting interrupts means that it isn''t possible to service the port rapidly even if we enabled interrupt-on-character-pending.'
