Before this change virtual ports control IOCBs were executed synchronously
via Execute IOCB mailbox command. It required exclusive use of scratch
space of driver and mailbox registers of the hardware. Because of that
shared resources use this code could not really sleep, having to spin for
completion, blocking any other operation.
This change introduces new asynchronous design, sending the IOCBs directly
on request queue and gracefully waiting for their return on response queue.
Returned IOCBs are identified with unified handle space from r292725.
The mdio driver interface is generally useful for devices that require
MDIO without the full MII bus interface. This lifts the driver/interface
out of etherswitch(4), and adds a mdio(4) man page.

I am not sure why this was split long ago, but I see no reason for it.
At this point this unification just slightly reduces memory usage, but
as next step I plan to reuse shared handle space for other IOCB types.
These are all works in progress. Notably - no wifi support just yet!

MSI-X interrupts are needed on some hardware, for example the Cavium
ThunderX only supports them, and with this we don't fall back to polling.

With some additional changes for AIM, that could also support much
larger physmem sizes. Given that 32-bit AIM is more or less obsolete, though,
it's not worth it at this time.

jmp_buf's size and alignment are baked into the ABI of third party libraries
and thus are very hard to change later so it is best to waste a small amount
