os: Add busfault_set_jmp() for SIGBUS unwind
...
Allow callers to arm a sigjmp_buf on a registered mapping so the
SIGBUS handler can siglongjmp instead of remapping and retrying the
faulting instruction.
Needed when the mapping contains objects that are unsafe to resume
on after a replace.
This is preparation work for the next commit where that mechanism is
used.

os: busfault: drop retval from busfault_init()
...
Nobody's ever looking at the return value - and in case of error,
there's not much we can do, but emit an error message.

os: fix missing include of misc.h in busfault.h
...
busfault.h is using FALSE, but didn't include misc.h, so it really
depends on include order whether it works.

include: move busfault.h out of public include dir
...
this header is isn't public, so it's more appropriate, where the actual
code is, which is the os/ directory.
