LibretroAdmin 032bad5dcf input: one pool of device numbers for the joypad driver and sources beside it ...

A port reads its controller by device number, and today that number is
the joypad driver's own slot. A pad no joypad driver sees - a
DualShock 3 bound to WinUSB - needs a number from the same pool, so
that it can sit beside the driver's pads without either taking the
other's.

input_device_pool.h keeps that pool. The driver's pads keep their slots
as their numbers, so nothing the driver reads changes. A source beside
it claims free numbers from the top down, and a pad that comes back is
given its number again if it is free. Where the driver's pad arrives on
a number a pad beside it holds, the driver's pad keeps it and the other
is named to move. The frontend marks the driver's numbers as it learns
of its pads, and clears them when the driver reports its pads afresh.
Nothing claims a number beside the driver yet; the WinUSB source will.

samples/input/device_pool runs the pool through mixed arrivals and
departures from the driver and two sources beside it.
