  Revert changes to shared code of the ixl and ixlv drivers to allow
  for easier long-term maintainability.

  Restrict the drivers to building on amd64 for now as it is
  only tested on that 64bit architecture.

  Just depend on PCI and neither INET nor INET6; also make sure we
  can build individual drivers and they do not depend on each other
  anymore.

Import HyperV Key-Value Pair (KVP) driver and daemon code by Microsoft,
many thanks for their continued support of FreeBSD.

While I'm there, also implement a new build knob, WITHOUT_HYPERV to
disable building and installing of the HyperV utilities when necessary.

The HyperV utilities are only built for i386 and amd64 targets.

MFC r271526: MFV r271510:

Enforce 4K as smallest indirect block size (previously the smallest
indirect block size was 1K but that was never used).

This makes some space estimates more accurate and uses less memory
for some data structures.

Illumos issue:
    5141 zfs minimum indirect block size is 4K

MFH (r272280, r272281, r272348): allow use with null user and rhost

MFC r268376 (imp):

  rm -rf can fail sometimes with an error from fts_read. Make it
  honor fflag to ignore fts_read errors, but stop deleting from
  that directory because no further progress can be made.

  When building a kernel with a high -j value on a high core count
  machine, during the cleanobj phase we can wind up doing multiple
  rm -rf at the same time for modules that have subdirectories. This
  exposed this race (sometimes) as fts_read can return an error if
  the directory is removed by another rm -rf. Since the intent of
  the -f flag was to ignore errors, even if this was a bug in
  fts_read, we should ignore the error like we've been instructed
  to do.
