Update discovery process initialization based on Andrew Morton's comments:

This update processes all enumerating mports first and schedules discovery
work after that. If the initialization routine fails to allocate resources

It is possible to configure a kernel which has xmon enabled, but has no
udbg backend to provide IO. This can make xmon rather confusing, as it
produces no output, blocks for two seconds, and then returns.
As a last resort we can instead try to printk(), which may deadlock or
otherwise crash, but t
The implementation of both xmon_enter() & xmon_leave() was removed in
commit 51d3082 "Unify udbg (#2)".
I can't find any reference to exc_prolog or dec_exc since the epoch.

Move a number of variables into their only user, reducing some of the
global variable clutter. They remain static, so their behaviour across
calls is unchanged.
Also use ARRAY_SIZE for regnames in scanhex().

read_spr() and write_spr() were both forgetting to clear catch_memory_errors,

These are not entirely equivalent to the old code. In most cases they
just gain a call to __delay() via end_bus_error_jump().
In symbol_lookup() we also move the printf() outside the protected area,
this should be safe as we are not derefencing the value we lookup, just
printing its value.

We have over 15 routines that implement essentially the same logic
in terms of catching faults. Pull the logic out into two helper
routines.
The pattern becomes:
if (start_bus_error_jump() == 0) {
end_bus_error_jump();
} else {

Currently xmon_depth_to_print is static and global, but it's only
ever used in xmon_show_stack().
At least with a modern compiler it's inlined, so there's no point
in it being static, we could #define it but it's only used in one
place.
By reworking the logic we can drop count and just decrement
We use STACK_FRAME_OVERHEAD in the exception vectors to establish
the exception frame, so it should be good enough to use here.

We have two #defines that rename scanhex() and skipbl() to
xmon_scanhex() and xmon_skipbl() - but no one ever uses those
names.
So the only effect is to rename the actual symbols in the generated
code, and AFACIS there is no reason to do that, so drop them.

The routines in start.c are only ever called from nonstdio.c, so if we
move them in there they can become static which is nice.
I suspect the idea behind the separation was that start.c could be
replaced in order to build xmon in userland. If anyone still cares about
doing that we could handle tha
xmon_getchar() is only called from within nonstdio.c, so make it static.

It looks like xmon_expect() was used for doing xmon over a modem (!?),
that code was dropped in 2005 in commit 51d3082 "Unify udbg (#2)".
Once xmon_expect() is gone xmon_read_poll() is unused, drop it too.
