wakeup() does not have any effect on pause(), so if a transfer was
not finished by the time of the first check, then the thread
would sleep full 30 ms.
To do: protect the transfer and interrupt code with the mutex,
switch from tsleep from msleep

When cache precedes files, and nscd is configured to allow negative caching,
commands like "pw groupadd" can fail. The sequence of events looks like:
1. A command like pkg(8) looks up the group, and finds it absent.
2. pkg invokes pw(8) to add the group
3. pkg queries the group, but nscd says it doesn't exist, since it has a
negative cache entry for that group.

MK_MALLOC_PRODUCTION option on -CURRENT.
Also, for the sake of backwards compatibility, support the old way of
enabling 'production malloc', e.g. by adding a define in make.conf(5).
MFC after: 1 week
X-MFC-With: r365371
For historical reasons, defining MALLOC_PRODUCTION in /etc/make.conf has
been used to turn off potentially expensive debug checks and statistics
gathering in the implementation of malloc(3).
It seems more consistent to turn this into a regular src.conf(5) option,
e.g. WITH_MALLOC_PRODUCTION / WITHOUT_MALLOC_PRODUCTION. This can then
be toggled similar to any other source build option, and turned on or
off by default for e.g. stable branches.

Other significant changes:
o new read-only variable .SHELL which provides the path of the shell
used to run scripts (as defined by the .SHELL target).
o variable parsing detects more errors.
o new debug option -dl: LINT mode, does the equivalent of := for all
variable assignments so that file and line number are reported for
variable parse errors.

For the TLS case where there is a "user@domain" name specified in the
X.509 v3 certificate presented by the client in the otherName component
of subjectAltName, a gid list is allocated via mem_alloc().
This needs to be free'd. Otherwise xp_gidp == NULL and free() handles that.
(The size argument to mem_free() is not used by FreeBSD, so it can be 0.)
This leak would not have occurred for any other case than NFS over TLS
with the "user@domain" in the client's certificate.
If multiple threads race calling vfs_hash_insert() while creating vnodes
with the same identity, all of the vnodes which lose the race must be
destroyed before any other thread can see them. Previously this was
accomplished by the vput() in vfs_hash_insert() resulting in the vnode's
VOP_INACTIVE() method calling vgone() before the vnode lock was unlocked,
but at some point changes to the the vnode refcount/inactive logic have caused
that to no longer work, leading to crashes, so instead vfs_hash_insert()
must call vgone() itself before calling vput() on vnodes which lose the race.

After OpenZFS import, zpool auto import behavior was moved to an
explicit "zpool import -a", and the zpool rc.d script was added
as a prerequisite of zvol.
However, in r299839, zvol was added as a prerequisite of dumpon,
making it to start very early and before all 'disks' providers.
At this time, dumping on a zvol is not supported, so remove this
requirement and make zpool depend on disks to allow zpool on
