meaning freeing all pages.

Overview:
* implemented quirk for forcing SATA interface enable
* restore value to status register - this enables link autonegotiation
Modifications:
* devid:vendorid field
* quirk for forcing PI setting (BIOS is doing that on PC-like systems)
* write to capabilites field to enable phy link initialization

This update brings few features:
o Support for the setmaster/dropmaster ioctls. For instance, they
are used to run multiple X servers simultaneously.
o Support for minor devices. The only user-visible change is a new
entry in /dev/dri but it is useless at the moment. This is a
first step to support render nodes [1].
The main benefit is to greatly reduce the diff with Linux (at the
expense of an unreadable commit diff). Hopefully, next upgrades will be
easier.
No updates were made to the drivers, beside adapting them to API
changes.

- Split the driver into independent pf and vf loadables. This is
in preparation for SRIOV support which will be following shortly.
This also allows us to keep a seperate revision control over the
two parts, making for easier sustaining.
- Make the TX/RX code a shared/seperated file, in the old code base
the ixv code would miss fixes that went into ixgbe, this model
will eliminate that problem.
- The driver loadables will now match the device names, something that
has been requested for some time.
- Rather than a modules/ixgbe there is now modules/ix and modules/ixv
- It will also be possible to make your static kernel with only one
or the other for streamlined installs, or both.
Enjoy!

This fixes C++ libraries not implicitly linking in libc++. This is
generally not an issue because the final linking with the compiled binary
will involve CXX via PROG_CXX or other means. It is however
inconsistent with libraries implicitly linking in libc and problematic
for trying to build libraries with '-z defs' to ensure all direct
dependencies are linked in.
libatf-c++ is currently the only consumer of this new feature.

The previous 12h AM/PM format was perplexing as it didn't follow the
locale of the user and was a minor annoyance to FreeBSD users coming
from Linux. Additionally, the man page was incorrect about the strftime
format.
There are three time formats that may be displayed in the STARTED
column depending on the age of the process. Below is an example.
For a process started at 14:30 on Monday 16 March 2015, the following
formats may be used:
14:30 for process < 24h old (24h Timestamp)
Mon14 for process > 24h, < 1 week old (Weekday Hour)
16Mar15 for process > 1 week old (Day Month Year)

code can read the buffer via sysctl or from a core file. In the core file
case there will be no nulterm, and the code copes with that, but now in the
sysctl case there is a nulterm (there didn't used to be). The least
disruptive way to restore the old behavior (and eliminate a spurious '\000'
at the end of the output) is to remove the nulterm (by decrementing the
buffer length) in the sysctl case.

This change comes from 8.15 but is being backported to FreeBSD releases
not yet using 8.15.

Use sbuf_new() + SYSCTL_OUT() instead of wiring the userland buffer and
using sbuf_new_for_sysctl(). The preallocated 256 byte buffer is always
going to be big enough to hold these results, and this should be more
efficient than wiring the old buffer.
INCLUDENUL is set and sbuf_finish() has been called, the length has been
incremented to count the nulterm byte, and in that case current length is
allowed to be equal to buffer size, otherwise it must be less than.
Add a predicate macro to test for SBUF_INCLUDENUL, and use it in tests, to
be consistant with the style in the rest of this file.
