geom/zero: Add support for unmapped I/O
This patch adds support for unmapped I/O to gzero(4).
Let's consider the following script to illustrate the change in
gzero(4)'s behavior:
```
dd="dd if=/dev/gzero of=/dev/null bs=512 count=100000"
dtrace -q -c "$dd" -n '
fbt::pmap_qenter:entry,
fbt::uiomove_fromphys:entry,
fbt::memset:entry
/execname == "dd"/
{
@[probefunc] = count();
}
'
```

ip6: Add explicit lock order information to catch LOR
Over the past several years, we have had sporadic reports of a lock
order reversal between the tcphash lock and the in6_ifaddr_lock.
These seems to be hard to reproduce reliably, and the WITNESS backtrace
points to code which uses the correct locking order.
This commit adds the correct lock order explicitly to help us detect
the call stack which uses the incorrect locking order.

sound: Retire snd_mixer->busy
Does not really serve any real purpose. It gets set on mixer_open() and
unset on mixer_close(), so it essentially tells us whether the mixer is
open or not.
mixer_close() uses it to return EBADF in case the mixer is not busied,
as in, the mixer has not been open()'d yet. This is redundant. The other
place where this is used is to decide whether to serve an ioctl issued
by userland, in which case it won't if, again, the mixer has not been
busied (i.e., opened). Again, seems redundant.

locale: tools: Make finalize idempotent
The finalize script renames source files with 3 components in their name
into names with two components with an @modifier, in the process.
Running the script for a second time without cleaning will strip the
@modifier from the files, producing invalid Makefiles and unusable
locales.
Prevent this by adding a guard at the beginning of the script.
Also, use a sub-shell for directory changes to avoid working directory
issues.
