It might be useful to provide a USB driver in the payload itself instead of in
libpayload. For example there are multiple payloads being built and linked
against the same libpayload, and they might not need or even want to have the
same set of drivers installed.
This change adds two new functions, usb_generic_create and usb_generic_remove,
which behave like the usbdisk_create and usbdisk_remove functions which are
defined for USB mass storage devices. If a USB device isn't recognized and
claimed by one of the built in USB class drivers (currently hub, hid, and msc)
and the create function is defined, then it will be called to give the payload
a chance to use the device. Once it's removed, if usb_generic_remove is
defined it will be called, effectively giving the payload notice.
Built and booted depthcharge on Link. Built depthcharge for Daisy. Built
a netbooting payload, called usb_poll() with those functions implemented, and
verified that they were called and that the devices they were told about were
reasonable and the same as what was reported by lsusb in the booted system.

Previously printf()'s were used to show USB messages
which results in lots of USB information being shown
when it isn't needed. This will now use the usb_debug()
printing funtion that already exists in usb.h.

The "debug" macro used internally in the libpayload USB subsystem was very
generically named and would leak into consumers of the library that included
usb.h directly or indirectly. This change turns that #define from a macro into
a static inline function to move away from the preprocessor, and also renames
it to usb_debug so it's less likely to collide with something unrelated.

This enables logical detachment of unresponsive usb devices (i.e.
devices not responding to control transfers) in the usb mass storage
driver. Without the detection of unresponsive devices we wait way too
long for the device to become ready.

- no need for the client of libpayload to implement
usbdisk_{create,remove}, just because USB was compiled in.
- usb hub support compiles, and works for some trivial cases (no device
detach, trivial power management)
- usb keyboard support works in qemu, though there are reports that it
doesn't work on real hardware yet.
- usb keyboard is integrated in both libc-getchar() and curses, if
CONFIG_USB_HID is enabled

memalign implementation (eg. the one I sent yesterday).
Features:
- UHCI controller driver
- UHCI root hub driver
- USB MSC (Mass Storage Class) driver
- skeleton of a USB HID driver
(requires better interrupt transfer handling, which is TODO)
- skeleton of a USB hub driver
(needs several blank spots filled in, eg. power management.
Again: TODO)
OHCI and EHCI are not supported, though OHCI support should be rather
easy as the stack provides reasonable abstractions (or so I hope). EHCI
will probably be more complicated.
Isochronous transfers (eg. webcams, audio stuff, ...) are not supported.
They can be, but I doubt we'll have a reason for that in the boot
environment.
The MSC driver was tested against a couple of USB flash drives, and
should be reasonably tolerant by now. But I probably underestimate
the amount of bugs present in USB flash drives, so feedback is welcome.
