Remove libhw

The entries for libhw* are no longer needed in .gitignore.

There is also no longer a difference between common-obj-y and
hw-obj-y, so one of those two macros is sufficient.

usb: Fix usb_packet_map() in the presence of IOMMUs

With the IOMMU infrastructure introduced before 1.2, we need to use
dma_memory_map() to obtain a qemu pointer to memory from an IO bus address.
However, dma_memory_map() alters the given length to reflect the length...

xhci: tweak limits

Set maxports to 15. This is what the usb3 route string can handle.

Set maxslots to 64. This is more than the number of root ports we
can have, but with additional hubs you can end up with more devices.

Set maxintrs (aka msi vectors) to 16. Should be enougth, especially...

ehci: Fix interrupt packet MULT handling

There are several issues with our handling of the MULT epcap field
of interrupt qhs, which this patch fixes.

1) When we don't execute a transaction because of the transaction counter
being 0, p->async stays EHCI_ASYNC_NONE, and the next time we process the...

net: clean up usbnet_receive()

The USB network interface has two code paths depending on whether or not
RNDIS mode is enabled. Refactor usbnet_receive() so that there is a
common path throughout the function instead of duplicating everything
across if (is_rndis(s)) ... else ... code paths....

net: fix usbnet_receive() packet drops

The USB network interface has a single buffer which the guest reads
from. This patch prevents multiple calls to usbnet_receive() from
clobbering the input buffer. Instead we queue packets until buffer
space becomes available again....

uhci: Don't queue up packets after one with the SPD flag set

Don't queue up packets after a packet with the SPD (short packet detect)
flag set. Since we won't know if the packet will actually be short until it
has completed, and if it is short we should stop the queue....
