767cb2e29d Remove overuse of exclamation marks in kernel printfs, there mere fact a
message has been printed is enough to get someones attention. Also remove the
line number for DPRINTF/DPRINTFN, it already prints the funtion name and a
unique message.

35d01728c6 Fix USB cache sync operations for platforms with non-coherent DMA.
- usb_pc_cpu_invalidate() is called between [consecutive] reads from a device,
  so a sequence of BUS_DMASYNC_POSTREAD and _PREREAD should be used. Note we
  cannot use or'ed shorthand ( _POSTREAD | _PREREAD) for BUS_DMASYNC flags, as
  the low level bus dma sync operation is implementation dependent and we
  cannot assume the required order of operations to be guaranteed.

- usb_pc_cpu_flush() is called before writing to a device, so
  BUS_DMASYNC_PREWRITE should be used.

USB CORE: busdma improvement

      For single segment allocations the boundary field
      of the BUSDMA tag should be zero. Currently all
      single segment allocations are less than or equal
      to 4096 bytes, so the limit does not kick in. If
      any single segment USB allocations would be greater
      than 4K, then it would be a problem.

ed6d949afd - Make struct usb_xfer opaque so that drivers can not access the internals
- Reduce the number of headers needed for a usb driver, the common case is just   usb.h and usbdi.h

8437751d86 Remove usb2_cv_* and just use the kernel condvar implementation, it was needed
earlier since condition variables didnt work with Giant but this was fixed 10
months ago.

f9cb546c23 Revert the size_t part of the last commit for the moment, this blows up the
USB_ADD_BYTES macro.

3e8739762f Unifdef __NetBSD__ here, the usb stack as a whole doesnt support NetBSD and it
obsfucates the code.

- Move tunable defines into usb_core.h and dependancy towards usb_defs.h
- Leave hardcoded defines in "usb_defs.h".
- Allow overriding all tunable defines.
- Add more customisable typedefs.
- Correct maximum device number.
