Modify lib/libstand/nfs.c to use NFSv3 instead of NFSv2.
This allows the nfs_getrootfh() function to return the
correct file handle size to pxe.c for pxeboot. It also
results in NFSv2 no longer being used by default anywhere
in FreeBSD. If built with OLD_NFSV2 defined, the old
code that predated this patch will be built and NFSv2
will be used. pxe.c is also modified to use this version
of nfs_getrootfh() so that pxeboot will use NFSv3 and
work for non-FreeBSD as well as FreeBSD NFS servers.
MFC: r212123
Modify nfs_diskless.c to recognize the environment variable
boot.nfsroot.nfshandlelen and set the diskless root fs to
use NFSv3 and this file handle length when it is set. If
this environment variable is not set, the diskless root fs
will use NFSv2 and the same defaults as before. This fixes
the problem where the diskless nfs root fs had to be on a
FreeBSD server for NFSv3 to work, because it did not know
the correct file handle length and assumed the size used
by FreeBSD.

MFC r211970:
Fix 'zfs allow' (maybe not only) returning:
cannot access dataset system/usr/home: Operation not supported
by including libzfs_impl.h. What libzfs_impl.h does is to redefine ioctl() to
be compatible with OpenSolaris. More specifically OpenSolaris returns ENOMEM
when buffer is too small and sets field zc_nvlist_dst_size to the size that
will be big enough for the data. In FreeBSD case ioctl() doesn't copy data
structure back in case of a failure. We work-around it in kernel and libzfs by
returning 0 from ioctl() and always checking if zc_nvlist_dst_size hasn't
changed. For this work-around to work in pyzfs we need this compatible ioctl()
which is implemented in libzfs_impl.h.

MFC: r212043
Add a null_remove() function to nullfs, so that the v_usecount
of the lower level vnode is incremented to greater than 1 when
the upper level vnode's v_usecount is greater than one. This
is necessary for the NFS clients, so that they will do a silly
rename of the file instead of actually removing it when the
file is still in use. It is "racy", since the v_usecount is
incremented in many places in the kernel with
minimal synchronization, but an extraneous silly rename is
preferred to not doing a silly rename when it is required.
The only other file systems that currently check the value
of v_usecount in their VOP_REMOVE() functions are nwfs and
smbfs. These file systems choose to fail a remove when the
v_usecount is greater than 1 and I believe will function
more correctly with this patch, as well.
MFC r211213:
The buffers b_vflags field is not always properly protected by
bufobj lock. If b_bufobj is not NULL, then bufobj lock should be
held when manipulating the flags. Not doing this sometimes leaves
BV_BKGRDINPROG to be erronously set, causing softdep' getdirtybuf() to
stuck indefinitely in "getbuf" sleep, waiting for background write to
finish which is not actually performed.
Add INVARIANTS checking that numfreebufs values are sane. Also add a
per-buf flag to catch if a buf is double-counted in the free count.
This code was useful to debug an instance where a local patch at Isilon
was incorrectly managing numfreebufs for a new buf state.

In protosw we define pr_protocol as short, while on the wire
it is an uint8_t. That way we can have "internal" protocols
like DIVERT, SEND or gaps for modules (PROTO_SPACER).
Switch ipproto_{un,}register to accept a short protocol number(*)
and do an upfront check for valid boundries. With this we
also consistently report EPROTONOSUPPORT for out of bounds
protocols, as we did for proto == 0. This allows a caller
to not error for this case, which is especially important
if we want to automatically call these from domain handling.
(*) the functions have been without any in-tree consumer
since the initial introducation, so this is considered save.

r210345:
* Deprecate `elf_getshnum()`, `elf_getphnum()` and `elf_getshstrndx()` in
favour of `elf_getshdrnum()`, `elf_getphdrnum()` and `elf_getshdrstrndx()`
respectively.
* Add new manual pages for `elf_getshdrstrndx()`, `elf_getphdrnum()` and
`elf_getshdrnum()`.
* Add a deprecation warning for `elf_getshstrndx()`, `elf_getphnum()` and
`elf_getshnum()`.
r210348:
Move helper functions `_libelf_ar_get_{name,number,string}()` and
`_libelf_ar_open()` to a new compilation unit "libelf_ar_util.c"
to break the circular dependency between "elf_memory.o" and
"libelf_ar.o".
r210325:
Bug fix: when updating headers using the gelf_update_*() functions,
the appropriate `dirty' bit needs to be set for both the Elf32 and
Elf64 case.
r210326:
Improve compatibility with other implementations of the ELF(3) API:
when an output file has no program headers, set the 'e_phentsize'
field of the ELF executable header to zero.
r210328:
Bug fix: permit the creation of zero-sized sections.
r210324:
- Correctly handle sections of type SHT_NOBITS. For these sections:
- elf_getdata() and elf_rawdata() should return an "Elf_Data" structure
that has its "d_buf" member set to NULL and "d_size" member set to
the nominal 'size' of the section.
- Update the manual page for these functions.
- Fix a memory leak in an error handling path inside elf_getdata().
- Use _libelf_allocate_data() in elf_newdata() for consistency.
r210438: (np)
Catch up with r210324. d_buf will be NULL for SHT_NOBITS sections, do not
attempt to copy from it in that case.
MFC r211922:
Add Intel Cougar Point PCH SATA Controller DeviceIDs. Correct some existing
entries for Intel Ibex Peak (5 Series/3400 Series) PCH SATA controllers.
MFC r211920:
Add Intel Cougar Point PCH SATA Controller DeviceIDs. Correct some existing
entries for Intel Ibex Peak (5 Series/3400 Series) PCH SATA controllers.
MFC r209652: sh: Remove comment that the comma operator is missing
in arithmetic expansion.
The comma operator is not listed in POSIX.1-2008 XCU 1.1.2.1 Arithmetic
Precision and Operations (referenced by XCU 2.6.4 Arithmetic Expansion) and
is therefore not required.
- Fix compilation of the subr_unit.c user space test program.
- Use %zu for size_t in a few format strings.
- Correct a comment typo.
- Assert that low and high are >= 0 in new_unrhdr().
