Add acquisition of a reference count on nfsv4root_lock in the
nfsd_recalldelegation() function, since this function is called
by nfsd threads when they are handling NFSv2 or NFSv3 RPCs, where
no reference count would have been acquired.
MFC: r211951
The timer routine in the experimental NFS server did not acquire
the correct mutex when checking nfsv4root_lock. Although this
could be fixed by adding mutex lock/unlock calls, zack.kirsch at
isilon.com suggested a better fix that uses a non-blocking
acquisition of a reference count on nfsv4root_lock. This fix
allows the weird NFSLOCKSTATE(); NFSUNLOCKSTATE(); synchronization
to be deleted. This patch applies this fix.

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.
Implement ip6proto_{un,}register() similarly to their legacy IP
counter parts to allow modules to hook up dynamically.

Perform additional checks when translating between file and memory

The ELF(3) API allows applications to request a conversion that is

have additional internal structure, such as those of type `Elf_Note',

type-specific headers that comprise the first few words in these

MFC r211648:
It seems some newer RTL8139 controllers provides only memory space
register mapping. I'm not sure whether it comes from the fact that
controllers live behind certain PCI brdge(PLX PCI 6152 33BC) and
the bridge has some issues in handling I/O space register mapping.
Unfortunately it's not possible to narrow down to an exact
controller that shows this issue because RealTek used the same PCI
device/revision id again. In theory, it's possible to check parent
PCI bridge device and change rl(4) to use memory space register
mapping if the parent PCI bridge is PLX PCI 6152. But I didn't try
to do that and we wouldn't get much benefit with added complexity.
Blindly switching to use memory space register mapping for rl(4)
may make most old controllers not to work. At least, I don't want
to take potential risk from such change. So use I/O space register
mapping by default but give users chance to override it via a
tunable. The tunable to use memory space register mapping would be
given by adding the following line to /boot/loader.conf file.
dev.rl.%d.prefer_iomap="0"
