MFC r292337, r292552, r292553:

Build mount_smbfs for arm. Also sort the subdirs.

Avoid unaligned memory accesses when encoding netbios names in libsmb.

The current code for encoding a netbios name converts each byte to a 16-bit
value and stores the result by casting a char* to u_short*, resulting in
alignment faults on strict-alignment platforms.

This change reimplements the encoding routine using only byte accesses to
memory. There is no particular reason to work with 16-bit values just
because the encoding process creates two bytes of output for every byte of
input. Working a byte at at time also avoids endian problems for big-endian
platforms.

Make the building of libsmb and mount_smbfs unconditional, now that r292552
has eliminated alignment and endian problems that were making it fail on
some platforms.

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.
