The tty interfacing via IM2 mode is a bit hackish for now. Unfortunately because

basically forced to use IM2.
Eventually we want to do IM2 properly anyway. The entire system is built around
a design that has proper interrupt handling.
With these changes sorted interrupts now work, and you can fail to find a root
file system. Next task is getting the fdc and root fs working.

kernel: Major rework of the single process in memory model
- Support 'parent runs first' in fork. We will also need this for flat memory
models like 68000 to work nicely. In our case we write the child to swap but
for flat models we'd duplicate the update and write a short stub stack to
the child
- Introduce a makeproc to replace newproc. Different arguments so deliberately
break all the old code
- Fix some interestingly bad scheduling corner cases where we have a process
running for a long time with nothing else that then causes fork to thrash
- Make tmpfree always a function. Useful for debug and also avoids icky asm
dependencies
- Fix the Z80 single process model to use the new features
- Fix the Z80 banked process model to pass the new arguments
- Also adjust the switching rate on the Plus 3 as our test platform for the
single process in memory tunings
Takes our boot time down about 33% !
