While looking at adding MIPS N32 ABI support to NetBSD, one of the
impediments I've stumbled across is the use of long which defining the various jmp_buf variants. In N32, long is not large enough to contain a
register value since registers are 64bits long.

To fix this, I want to add __jbslot_t to <machine/ansi.h> which will be
typedef'ed to long except which N32 is used on MIPS.

I'll then change <setjmp.h> to use jbslot_t instead of long.

Don't we already have a register_t for this kind of thing?

Can't use it due to namespace pollution from <machine/types.h> which lots of other crap.
