Add the necessary bits to enable kernel breakpoints for Book-E. The entrypoint
for program exception is very trivial, so rather than expand it to be similar to
AIM, add it into the standard trap handler.
This wasn't blocked out as Book-E specific because it is only a minor redundancy
over AIM, which should have already called db_trap_glue() at this point. If
it's going to panic with a fatal trap anywya, it doesn't matter if it goes
through this path again.
When committing DTrace in 2012/2013 era I inadvertently broke breakpoints, by
setting EXC_DTRACE to the same value as BKPT_INST. Change EXC_DTRACE to a
different, yet logically identical, trap (tw <all>,31,31).

RSS hash type will be used to identify the CPU on to which, a receive packet
will be queued. This patch extracts the "RSS hash type" from the receive
completion and sends it to the stack.

The fixed is used only to fix up buggy MPTable information and the
trigger mode is probably ignored for the relevant interrupt types
anyway. Still, it's better to be standards compliant and have the code
do what it says it does.

During acpi_cmbat_attach() the acpi_cmbat_init_battery() notification
handler is registered. It has been observed this notification handler
can be called instantly, before the attach routine has returned. In
the notification handler there is a call to device_is_attached() which
returns false. Because the softc is set we know an attach is in
progress and the fix is simply to wait and try again in this case.

- Use ni_txparms directly instead of calculating them manually every time
- Move M_EAPOL flag check upper; otherwise it may be skipped due to
'ucastrate' / 'mcastrate' check
- Use 'mgtrate' for control frames too (see ifconfig(8), mgtrate parameter)
- Add few more M_EAPOL checks where it was missing (zyd(4), ural(4),
urtw(4))
- Few unrelated cleanups
Tested with:
- Intel 6205 (iwn(4)), STA mode;
- WUSB54GC (rum(4)), HOSTAP mode + RTL8188EU (rtwn(4)), STA mode.

Currently only H3 is supported with almost the same state as HEAD.
