SVN rev 229370 on 2012-01-03 09:15:54Z by hselasky

MFC r228483, r228640, r228709, r228711, r228723 and r229086:
 - Implement better support for USB controller suspend and resume.
 - Add code to wait for USB shutdown to be executed at system shutdown.
 - Add sysctl which can be used to skip this waiting.

NOTE: All USB controller drivers needs to be re-compiled after
this change due to changes in some USB controller only structures.

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

MFC r214349:
The EHCI_CAPLENGTH and EHCI_HCIVERSION registers are actually sub-registers
within the first 4 bytes of the EHCI memory space. For controllers that

return the wrong values. Instead, read the combined register with a
4-byte read and mask out the interesting quantities.

Revert most of r197682 (EHCI Hardware BUG workaround). Implement
proper solution which is to not use the TERMINATE pointer, but rather
link to a halted TD. The initial fix was due to a misunderstanding
about how the EHCI hardware works. Thanks to Alan Stern for clearing
this up. This patch can increase mass storage read performance
significantly when the IRQ rate is less than 8000 IRQ/s.

MFC r199058

 Integrate lost interrupts patch from the old USB stack.

 Some EHCI chips from VIA / ATI seem to trigger interrupts before writing back
 the qTD status, or miss signalling occasionally under heavy load.  If the host
 machine is too fast, we can miss transaction completion - when we scan the
 active list the transaction still seems to be active. This generally exhibits
 itself as a umass stall that never recovers.

 We work around this behaviour by setting up this callback after any softintr
 that completes with transactions still pending, giving us another chance to
 check for completion after the writeback has taken place

 EHCI Hardware BUG workaround

 The EHCI HW can use the qtd_next field instead of qtd_altnext when a short
 packet is received. This contradicts what is stated in the EHCI datasheet.
 Also the total-bytes field in the status field of the following TD gets
 corrupted upon reception of a short packet!  We work this around in software by
 not queueing more than one job/TD at a time of up to 16Kbytes! The bug has been
 seen on multiple INTEL based EHCI chips.  Other vendors have not been tested
 yet.

 - Applications using /dev/usb/X.Y.Z, where Z is non-zero are affected, but not
   applications using LibUSB v0.1, v1.2 and v2.0.
 - Mass Storage (umass) is affected.

Provide a better commit log for r190735, forced by making a whitespace change.

Refactor how we interface with the root HUB. This is achieved by making a
direct call from usb2_do_request to the host controller for root hub requests,
this call will perform the controller specific register read/writes and return
the error code.

This cuts out a lot of code in the host controller files and saves one thread
per USB bus.
