nvme: There's 64 LBAF descriptors, not 16
Older versions of the standard were limited to 16, but the actual limit
is 64. Bump the limit to 64. This should be a #define, but there's no
good standardized name, so I'm punting on that. All the places that use
it, apart from the byte swapping code, do the right thing and use the
nlbaf field to limit what to access.

kern: Remove needless kern.opts.mk
We don't need kern.opts.mk in any of these places. None of these
Makefiles reference any MK_ options. Some don't even need SYSDIR,
but leave that defined in the ones that do.

modules: Simplify some expressions
When we only use SYSDIR once or twice, expand it and don't define
it. Minor other consistency changes.

kern: Don't need bsd.own.mk
Instead, replace it with bsd.init.mk and remove old comments about
FreeBSD 10.x compat. We used to need bsd.own.mk, but now can suffice
with bsd.init.mk since kern.opts.mk doesn't included that in too many
places.

nullfs: add nounixbypass mount option
The option, when set, disables bypassing the unix socket vnode down
to the lower mp, effectively preventing connection to nullfs unix
socket from being acceptable from the lower mp (and vice versa).
This is done by providing a vop vector that stops bypass for unp-related
VOPs. I believe that VFS_VOP_VECTOR_REGISTER() does the right thing
there regardless of the order of initialization.

nfsuserd: Fix OOB access on membership of too many groups, take 2
Forgot to reset 'ngroup' after one of the calls to getgrouplist() in the
previous commit with same title (referenced also below).

initgroups.3: Clarify that ENOMEM is a possible value for 'errno'
The current phrasing could be interpreted as meaning that initgroups(3)
could return ENOMEM instead of -1, which it actually did until I fixed
it in commit 0b018cfd81d8 ("initgroups(3): Fix return value on
allocation failure").
While here, mention setgroups(2) as a system call rather than a library
function.

nfsuserd: Fix OOB access on membership of too many groups
getgrouplist() sets the variable containing the allocated length in
input to the full effective group list length, not the number of slots
that were actually filled in case the passed array is too small to
contain it.
While here, on this condition, improve the error message by outputting
the corresponding user name.

getgrouplist.3: Insist on the value returned in 'ngroups'; Minor changes
Emphasize the peculiar treatment of 'ngroups', through which the
effective group list's size is returned, even if the passed allocated
size is not big enough, in which case the output 'groups' array is
completely filled with the effective group list's first elements.
Use the precise POSIX term for the group associated to the user in the
password database ("initial numerical group ID"), consistently with what
was done in initgroups.3.
Use "length" instead of "size" to refer to the number of elements of an
array (in contrast with its actual size in bytes).
Perform some minor simplifications on top of the last rework.
