NOTES: Multiple schedulers can be compiled in at once

Mention that ULE is the default scheduler when multiple ones are
compiled in and how the tunable 'kern.sched.name' can be used to select
another one.

While here, regroup SCHED_ULE and SCHED_4BSD, as they control if the
respective scheduler instances are compiled in, putting SCHED_STATS
aside.

ice: Add a failure injection facility

Add compile-time optional, non-sleeping fail points around every VF
creation resource boundary, before VF VSI reconstruction, and in the
GET_STATS validation path.

Provide an ICE-wide wrapper and device selector so other driver
subsystems can add scoped points without duplicating the failpoint
plumbing. Keep the current SR-IOV points and VF selector in an iov
child namespace.

Compile the facility only with options DRIVER_FAILPOINTS. This shared
option avoids a separate kernel option for every driver that provides
test-only injection hooks. Ordinary kernels contain no ICE failpoint
objects or sysctl nodes. Require an exact PF device name and
optionally a VF index before any point can fire. This prevents a stale
test setting from affecting another PF.

The hooks exposed two reset-lifetime defects while validating the
existing SR-IOV review series. A PF reset could discard a firmware VSI
before teardown, and a rebuilt sibling could leave stale switch-filter
state after IOV destroy.

Tested on an E810-XXV with INVARIANTS and WITNESS. All twelve creation
checkpoints rolled back and permitted immediate resource reuse. Forced
reconstruction and malformed GET_STATS failures also preserved sibling
operation and reply cardinality.
