On Linux, /proc/<pid>/fd is comparable to fdescfs, where it allows you
to inspect the file descriptors used by each process. Glibc's ttyname()
works by performing a readlink() on these nodes, since all nodes in this
directory are symlinks.
It is a bit hard to implement this in linprocfs right now, so I am not
going to bother. Add a way to make ttyname(3) work, by adding a
/proc/<pid>/fd symlink, which points to /dev/fd only if the calling
process matches. When fdescfs is mounted, this will cause the
readlink() in ttyname() to fail, causing it to fall back on manually
finding a matching node in /dev.

- Remove dosansi, pc and pc3. I suspect nobody ever needs these.
- Add vt100, screen and xterm-color.
This file is now probably more than sufficient in most cases, even for
common use outside single user mode, where people just use the console
driver, a graphical terminal emulator and a terminal multiplexer.
Right now we have a termcap.small in the tree, but we don't install it.
If we do install this file by default, it is more likely for
applications to work in single user mode.
I am not entirely happy with the contents of this file. In my opinion we
should remove the `dosansi', `pc' and `pc3' entries and replace them
with `vt100' in case someone uses a serial console.
The file does already have entries for `cons25' and `xterm', which is
used most often.

or overflow the netisr queue and fall back to the interface
queue so that we can garuantee that the ifnet pointer stays
valid. Formerly we ended up with reference counts <= 0 in
case the netisr had returned ENOBUFS. The idea is to track
any packet in the netisr queue and only change the refount
on edge operations for the fallback interface queue. This
also avoids problems in case the if_snd.ifq_len lies to us.
Also rework refount assertions to make sure they trigger if
we go below 1. Formerly a negative refence count did not
trigger the assert as the refcount variable is u_int.

POSIX says: "The input file shall be a text file", nothing more,
so the text file with illegal sequence is valid input.
BTW, GNU sort does not fails on EILSEQ too.

At least in RELENG_7 this fixes some start problems for some programs
from the ports. It is also more correct, as a jail shall not expect
input (interactivity) from the jail-host.
Revert the current behavior of starting jails in the background and
make it optional only for the start of jails (jail_parallell_start=YES
in rc.conf):
- The stop can not be done in the background, the system needs to wait
until everything is stopped correctly before it can reboot or power
down.
- The start should not be done in parallel by default, this not only
breaks POLA for people comming from RELENG_x, it may also break a
dependency chain with other scripts in the jail-host, which need to
do some stuff after the jails are up and running (e.g. hardlinking
a mysql socket from one jail into another one).

In order to do that cleanly, lapic_setup_clock(), on both ia32 and amd64,
now accepts as arguments the desired sources to handle, and returns the
actual ones (LAPIC_CLOCK_NONE is forbidden because otherwise there is no
meaning in calling such function).
This allows to bring out into commont x86 code the handling part for
machdep.lapic_allclocks tunable, which is retained.
