keyboard_init attempts to read the existing mode register, set the
'XLATE' bit, and write it back. The implementation is buggy because the
keyboard may be active at the time we read the mode, and we can
misinterpret scancode data as the reply to our command. It leads to
problems where the KB gets disabled in firmware.
In fact, setting the 'XLATE' bit is completely unnecessary, even if we
desire QEMU keyboard support. We already set this bit when we initialize
the keyboard in pc_keyboard_init. Basically, this code does nothing
(or worse), so just remove it.

And include the new, split out version in drivers/keyboard.c and
drivers/usb/usbhid.c. Those files were including curses.h just for those
definitions, but the include path was only fixed up to to point to the
libpayload versions of those files if one of the variants of curses was
compiled in. If neither was, gcc would fall back to the system version of that
header which is wrong.

The PS/2 keyboard driver set and reset the caps LED to show the
keyboard status. Unfortunately, that configuration happens over
the same path used to transmit keypresses.
In face of certain error conditions, the keyboard stopped working.
This change makes keyboard handling more robust.

The new build system uses quite a few more -W flags for the compiler by
default than the old one. And that's for the better.

Rename the generated config file to libpayload-config.h to differenciate
it from other config.h files. Move the default location of the file to
$(src)/include so that LIBPAYLOAD_PREFIX= users can access the file

keyboard, video, usb) can attach.
The only things left with #ifdefs are initialization (at some point
the drivers must get a chance to register)

- 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

Patrick Georgi explained:
The |0x80 codes are "break codes", that means, codes that are emitted
when the key transitions from pressed to non-pressed, so the modifier
was always in the wrong state, as soon as you pressed shift for the
first time.
