Another hook needed for wireless USB: there are states associated with the
device authentication protocol. Wireless devices must authenticate using
the host system's keystore.
Note that wired connections could also use this authentication protocol, if
for no other reason than to support the most secure "simple" key exchange
protocols for wireless devices.

This patch for usb_ch9.h includes linux/types.h instead of asm/types.h so that
__le16 and so on is explicitly defined. It also cleans up non standard //
comment.

This provides declarations for new requests, descriptors, and bitfields as
defined in the Wireless USB 1.0 spec. Device support will involve a new
"Wire Adapter" device class, connecting a USB Host to a cluster of wireless
USB devices. There will be two adapter types:
* Host Wireless Adapter (HWA): the downstream link is wireless, which
connects a wireless USB host to wireless USB devices (not unlike like
a hub) including to the second type of adapter.
* Device Wireless Adapter (DWA): the upstream link is wireless, for
connecting existing USB devices through wired links into the cluser.
All wireless USB devices will need persistent (and secure!) key storage, and
it's probable that Linux -- or device firmware -- will need to be involved
with that to bootstrap the initial secure key exchange.
Some user interface is required in that initial key exchange, and since the
most "hands-off" one is a wired USB link, I suspect wireless operation will
usually not be the only mode for wireless USB devices. (Plus, devices can
recharge batteries using wired USB...) All other key exchange protocols need
error prone user interactions, like copying and/or verifying keys.
It'll likely be a while before we have commercial Wireless USB hardware,
much less Linux implementations that know how to use it.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
