a3cea30b50 Implement an USB memory reserve. Allocate some memory per host controller 
in the wanted bus_dma space. If an allocation fails during operation
(i.e. when hotplugging an umass device), fall back to using the reserve.

The amount can be configured as USB_MEM_RESERVE. The default value is
256k.

Ideally, there would be a way to steal pages in the desired area from
UVM, but that's far more complicated, and this is not intrusive, plus
it works.

ac575d2a58 Make one message dependent on ohcidebug, so it doesn't interfere with polled 
operation; e.g. when entering a root device or in DDB.

ce925f4f4f Interrupt descriptors might become invalid while being processed in 
uhci_check_intr - so remember their next pointer before calling it.
Patch provided by Matthew Orgass in PR kern/24542.

05069ebd4d Use the correct wValue to get hub desriptors. 
Also, make wValue checks of root hub codes less strict.

3204b83aa5 Be somewhat more persuasive about enabling the port on a port reset. 
USB protocol dictates that the port enable must be implied by the port
reset. To implement this on (at least) the VIA VT83C572 this means we
need to wait around tweaking the chip state until the port actually
transitions to enabled (or the device goes away).  Likely fixes
kern/11018.

06de426449 SIMPLEQ rototill: 
- implement SIMPLEQ_REMOVE(head, elm, type, field).  whilst it's O(n),
  this mirrors the functionality of SLIST_REMOVE() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
  this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
  singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
