When pages are freed to a bounce zone, only maps waiting for pages for
that zone can make forward progress. If a map for a different bounce
zone is at the head of the global list, then requests that could
otherwise make forward progress will be stalled waiting on the other
bounce zone. If bounce zones shared bounce pages then a global list
would still make sense to prevent "later" requests from starving an
earlier request but that is not a concern with per-zone bounce page
pools.

mld_domifattach() does a memory allocation under the global MLD mutex
and so can fail, but no error handling prevents a null pointer
dereference in this case. The mutex is only needed when updating the
global softc list; the allocation and static initialization of the softc
does not require this mutex. So, reduce the scope of the mutex and use
M_WAITOK for the allocation.

Coverity points out that if counter was NULL when passed to
pfr_pool_get() we could potentially end up dereferencing it.
Happily all users of the function pass a non-NULL pointer. Enforce this
by assertion and remove the pointless NULL check.

Move the use of 'sc' to after the NULL check.
It's very unlikely that we'd actually hit this, but Coverity is correct
that it's not a good idea to dereference the pointer and only then NULL
check it.

The presence of the latter causes a link error when building a
statically linked ctfdump(1) because libc defines the same symbol.
libc's warn() is defined as a weak symbol and so does not cause the same
problem, but let's just use libc's version.

Use the drop and enable endpoint context commands to force a reset of
the data toggle for USB 2.0 and USB 3.0 after:
- clear endpoint halt command (when the driver wishes).
- set config command (when the kernel or user-space wants).
- set alternate setting command (only affected endpoints).
Some XHCI HW implementations may not allow the endpoint reset command when
the endpoint context is not in the halted state.

If iommu_gas_match_one has to adjust for a boundary crossing, its
check against maxaddr includes 'offset' in its calculation, to ensure
that the allocated memory does not exceed the max address. However, if
there's no boundary crossing adjustment, then the maxaddr check
disregards 'offset'. Fix that.
