ec8b828fc4 Make uhci_waitintr() robust to interrupts being enabled, even though
it is expected that they will not be enabled at the time that it
is called. This is reported to work around a problem in RELENG_4
where the kernel panics on boot if FAST_IPSEC and crypto support
are enabled.

326b4d74c4 When resuming after a system suspend, re-issue the UHCI_CMD_MAXP
command in case this setting was not saved. Since bandwidth reclamation
(-current only) often results in bus activity continuing to the end
of every frame, most transfers would fail with IOERROR if this
setting is missed.

fe74650816 In rev 1.51 of usb_port.h I switched over to using the USB_USE_SOFTINTR
code path to fix a bug in the non USB_USE_SOFTINTR path that caused
the usb bus to hang and generally misbehave when devices were unplugged.
In the process though it also reduced the throughput of usb devices because
of a less than optimal implementation under FreeBSD.

This commit fixes the non USB_USE_SOFTINTR code in uhci and ohci
so that it works again, and switches back to using this code path.

The uhci code has been tested, but the ohci code hasn't.  It's
essentially the same anyway and so I don't envisage any difficulties.

tweaked by sysctl we don't need to go through hoops to get the
different usb parts to produce debug data.

b4dc6ff9bc Remove some strange code that allocates memory and then immediately
frees it again. The idea was to perform M_WAITOK allocations in a
process context to reduce the risk of later interrupt-context
M_NOWAIT allocations failing, but in fact this code can be called
from contexts where it is not desirable to sleep (e.g. if_start
routines), so it causes lots of witness "could sleep" warnings.

90ce56c287 Add the following functions/macros to support byte order conversions and
device drivers for bus system with other endinesses than the CPU (using
interfaces compatible to NetBSD):

- bwap16() and bswap32(). These have optimized implementations on some
  architectures; for those that don't, there exist generic implementations.
- macros to convert from a certain byte order to host byte order and vice
  versa, using a naming scheme like le16toh(), htole16().
  These are implemented using the bswap functions.
- stream bus space access functions, which do not perform a byte order
  conversion (while the normal access functions would if the bus endianess
  differs from the CPU endianess).

htons(), htonl(), ntohs() and ntohl() are implemented using the new
functions above for kernel usage. None of the above interfaces is currently
exported to user land.

Make use of the new functions in a few places where local implementations
of the same functionality existed.
