Switch to USB_USE_SOFTINTR. The callout hack does indeed work
fine for systems without generic soft interrupts, even if it is
a little sub-optimal. Consider it a penalty for ports not
implementing a kernel API.
Addresses kern/11957. The PR has been open for 4 months, and
I have work blocked on the continued existence of splimp() in
the networking code.
The NetBSD patch only switches it on for NetBSD, but I've also
switched it on for FreeBSD in this commit.

attachment after boot in some cases where the device gets confused if
spoken to over two different pipes simultaneously (resulting in TIMEOUT
errors on requesting INQUIRY data).
This solution is far from perfect, as after umass_attach has returned
the USB stack fetches the string descriptors in order for creating the
event that is sent to userland. It just makes the chances of collisions
less likely.

do that by supplying vendor and product locators for the generic one.

(because we register the interrupt with IPL_SOFTNET). However, if
we're using a callout, then splusb == splsoftclock (because the
callouts happen from the softclock interrupt).
Note that splsoftnet blocks softclock interrupts, but this is
meant to better describe what's going on.

Change the operation of the USB event thread. Before it only

general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.
