check length of the pathname in the range 0<=n<=NFS_MAXPATHLEN,
not 0<n<=NFS_MAXPATHLEN. This fixes a minor interoperability problem
that the FreeBSD NFS server did not allow a symlink pointing the empty
pathname.

mbuf. First moves toward being able to cope better with having layer 2 (or
other encapsulation data) before the IP header in the packet being examined.
More commits to come to round out this functionality. This commit should
have no practical effect but clears the way for what is coming.

in a previous commit to avoid namespace collisions, unfortunately I missed two
of them. This leads to the ip alias being incorrectly removed in some cases
when using the stop command.

/boot/kernel can fail. Try to remove /boot/kernel.prev and cope the
best we can if that fails.

the number of unnecessary wakeups issued whenever the framework becomes
idle.
Annotate that we still signal the CV more than necessary and should
fix this.

Redo the checking for 2.6 emulation. We now cache the value of
use26 and replace calls to linux_get_osrelease() + parsing with
a call to linux_use26(). Typical path is lockless now.
Pointed out by: kib
This allows to ship RELENG_7_0 with a default osrelease of 2.4.2 and the
possibility to enable 2.6.x emulation without the possible performance
impact of the previous version of the check.

interpreted $command. Some "portable" sofware packages use such a
line to skip the task of figuring out the absolute pathname of the
interpreter at install time, e.g.:
#!/usr/bin/env python
It is insecure, but a popular book on Python seems to have advised
it to a wide audience. Hence a number of such scripts in the ports,
mostly written in Python.
