CI will fail from this commit onward. Currently working:
$ bootstrap translate init.linux 0[4-7]*.subx 080zero-out.subx -o a.elf && ./a.elf test
$ bootstrap run a.elf test
$ chmod +x a.elf; ./a.elf test
Plan: migrate functions that used to return handles to pass in a new arg
of type (addr handle). That's a bit of a weird type. There should be few
of these functions. (Open question: do we even want to expose this type
in the Mu language?)
Functions that just need to read from heap without modifying the handle
will receive `(addr T)` or `(handle T)` types as arguments.
As I sanitize each new file, I need to update signatures for any new functions
and add them to a list. I also need to update calls to any functions on
the list.
At the SubX level we have to put up with null-terminated kernel strings
for commandline args. But so far we haven't done much with them. Rather
than try to support them we'll just convert them transparently to standard
length-prefixed strings.
In the process I realized that it's not quite right to treat the combination
of argc and argv as an array of kernel strings. Argc counts the number
of elements, whereas the length of an array is usually denominated in bytes.
