7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

528d1a7fbc Replace the FOO_DEBUG definitions with USB_DEBUG, and switch the
debugging levels to off by default.  Now that debug levels can be
tweaked by sysctl we don't need to go through hoops to get the
different usb parts to produce debug data.

7cca309311 Use usb_callout_init() instead of directly calling callout_init() with
NetBSD's expected arguments.  This unbreaks the kernel compile.

    Change the operation of the USB event thread.  Before it only
    performed USB device discovery, now it can also perform (short)
    tasks for device drivers that need a process context, but don't
    have one.  This is not pretty, but better than using busy-wait
    in an interrupt context.

7b77e0fa50 Activate the kthread mechanism for doing usb bus discovery. This means
that device add/remove will work without usbd running.  usbd is still
used for execing stuff, but that is all now.  Ideally it could be replaced
by a devd some day.  Until now, usbd had to be running so that the
USB_DISCOVER ioctl could be called to walk the tree when an attachment
status change was noticed.

Among the changes:
- when a detach happens, remove any pending 'attach' messages or the system
suffers from whiplash from exec moused / kill moused loops if you do lots
of attach/detach and later start usbd.
- tweaks related to kthread differences
- disable the select handler for the old interface (never return success).
I have not removed it yet or old usbd's will abort.  That can get removed
later once usbd is cleaned up and things have stabilized for a few weeks.
- get Giant in the kthread.
- a couple of minor potential bug fixes (usb_nevents vs malloc failure etc)
