The ISA bus IRQ range is 0..15. What isa_irq_handler and IsaIrqState are
actually dealing with are the Global System Interrupts. Refactor the
code to clarify this.

IsaIrqState::ioapic is always non-NULL. Probably, the concrete

qemu_set_irq.

These boards carry similar hardware: SDRAM (48M for LX110, 64M for LX60,
96M for LX200), 16 Mbyte FLASH, FPGA, 10/100 Mbps Ethernet PHY and 16550
UART. FPGA may be loaded with almost any Tensilica processor. It is also
used to implement Ethernet MAC, e.g. OpenCores 10/100 Mbps Ethernet MAC
and LED/DIP switches access.

QEMU timer is used to post CCOMPARE interrupt when the core is halted.
If that CCOMPARE interrupt is masked off then the timer must be rearmed
in the callback, otherwise it will be rearmed next time the core goes to
halt by the waiti instruction.

Add test case into timer testsuite.

Calling usb_packet_complete() recursively when passing up the completion
event up the chain for devices connected via usb hub will trigger an
assert.  So don't do that, make the usb hub emulation call the upstream
completion callback directly instead.

qemu uses the ps/2 mouse by default.  The usb tablet (or mouse) is
activated as soon as qemu sees some guest activity on the device,
i.e. polling for HID events.  That used to work fine for both fresh
boot and migration.

Remote wakeup support changed the picture though: There will be no
polling after migration in case the guest suspended the usb bus,
waiting for wakeup events.  Result is that the ps/2 mouse stays
active.

Fix this by activating the usb tablet / mouse in post_load() in case
the guest enabled remote wakeup.

Honour the maximum packet size for endpoints; this applies when
sending non-isochronous data and means we transfer only as
much as the endpoint allows, leaving the transfer descriptor
on the list for another go next time around. This allows
usb-net to work when connected to an OHCI controller model.

commit 891fb2cd removed the implicit
detach before (re-)attaching in usb_attach().  Some usb host controllers
used that behavior though to do a port reset by a detach+attach
sequence.

This patch establishes old behavior by adding a new usb_reset() function
for port resets and putting it into use, thereby also unifying port
reset behavior of all host controllers.  The patch also adds asserts to
usb_attach() and usb_detach() to make sure the calls are symmetrical.
