* i386/i386/idt.c: add selector for the interrupt-specific stack
* i386/i386/ktss.c: configure ist1 to use a dedicated stack
* i386/i386/trap.c: add double fault handler, which just prints the
state and panics. There is not much else to do in this case but it's
useful for troubleshooting

The actual values are not saved together with the rest of the thread
state, both because it would be quite espensive (reading MSR, unless
rdfsbase instructions are supported, but that's optional) and not
really needed. The only way the user has to change its value is with a
specific RPC, so we can
* i386/i386/db_interface.c: don't set unused segment selectors on full
64-bit
* i386/i386/db_trace.c: likewise.
* i386/i386/i386asm.sym: likewise.
* i386/i386/pcb.c:: likewise.
* i386/i386/thread.h: remove ES/DS/FS/GS from thread state on !USER32,
as they are unused in this configuration. Only
* x86_64/locore.S: ensure the thread state is filled completely even
on recursive interrups. The value of the segment selectors is not
very important in this case, but we still need to align the stack to
the bottom of i386_interrupt_state.
