65c816: first sketch of needed code
Lots to fill in yet but this is the basic idea
- Load kernel somewhere
- Bank 0 gets the CPU stacks
- Each process gets a bank
- Kernel gets stuffed in bank 0 if it'll fit, somewhere else if not
- C code runs with cc65 so it's using an external C stack in its own bank
which should mean we don't have to worry about funny stack accesses (and
can fix any in the support lib)
Processes aren't allowed to do long operations, or to save/restore bank
registers. Only awkward one here is the block move ops. We probably need
a blockmove 'syscall' that puts in th banks and avoids a process moving
bank while mvn/mvp executes (as it's interruptible).
As there is only one configuration of banking we can hopefully put all the glue
in the shared file to make platform support easier.

smallc: remove literal buffer
Restructure the code so that literal data is generated inline relying upon the
assembler segment functionality to sort out the interleaving. A platform whose
assembler isn't good enough can always switch between two files...
This saves us about 3K and means that the literal space is no longer limited
to 2.5K per compiled file.
You stil can't initialize pointers but the framework is now there to do this.
