usb-host: handle guest-issued clear halt

Most important here is to update our internal endpoint state so we know

usb-host: don't dereference invalid iovecs

usb-host assumes the first iovec element is always valid.
In case of a zero-length packet this isn't true though.

usb-host: fix zero-length packets

usb-host optimizes away zero-length packets by not entering the
processing loop at all. Which isn't correct, we should submit a
zero-length urb to the host devicein that case. This patch makes

usb-host: rewrite usb_linux_update_endp_table

This patch carries a complete rewrite of the usb descriptor parser.
Changes / improvements:

Add bootindex support to usb-host and usb-redir

When passing through a usb pendrive seabios will present it in the F12
boot menu and will happily boot from it.

This patch adds bootorder support so you can even make it the default
boot device.

usb: the big rename

Reorganize usb source files. Create a new hw/usb/ directory and move
all usb source code to that place. Also make filenames a bit more
descriptive. Host adapters are prefixed with "hch-" now, usb device
emulations are prefixed with "dev-". Fixup paths Makefile and include...
