Vendor import of OpenSSH 6.6p1.
Remove unneeded fake _KERNEL definition.
Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental.

This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.

armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
 * WITH_ARM_EABI
 * WITHOUT_GCC
 * WITHOUT_GNUCXX

In addition, without an external toolchain, the following need to be left
as their default:
 * WITH_CLANG
 * WITH_CLANG_IS_CC

As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.
Add the llvm/clang patch for r263619.
For the moment also disable interrupts on the altera-jtag-uart imitation
and force polling mode.
Reorder the pmap macros so "ARM_MMU_V6 + ARM_MMU_V7" is first. As they are
identical this allows us to build for both v6 and v7 together.
lldb: Invoke PT_KILL from ProcessPosix::DoDestroy

We previously sent SIGKILL to the debuggee in DoDestroy, but did not
actually detach or kill via ptrace.  It seems that this somehow didn't
matter on Linux, but did on FreeBSD.

This would happen when quitting LLDB while stopped at a breakpoint, for
example.  The debuggee remained stopped in ptrace (with the signal
either pending or lost).  After a timeout of a second or two LLDB exits,
which caused the debuggee to resume and dump core from an unhandled
SIGTRAP.

BringProcessIntoLimbo is a poorly named wrapper for ptrace(PT_KILL)
which is the desired behaviour from DoDestroy.

Add a pre-merge script which reverts mechanical changes such as added
$FreeBSD$ tags and man page dates.

Add a post-merge script which reapplies these changes.

Run both scripts to normalize the existing code base.  As a result, many
files which should have had $FreeBSD$ tags but didn't now have them.

Partly rewrite the upgrade instructions and remove the now outdated
list of tricks.
Add a note to UPDATING about customized kernel configuration files now

Adds the ADC driver for TI AM3xxx SoC family.

The ADC has a 12bit resolution and its raw output can be read via sysctl(8)
interface.

The driver allows the setup of ADC clock, samples average and open delay
(the number of clock cycles to wait before start the conversion).

The TSC_ADC module is set in the general purpose mode (no touchscreen
support).

Tested on Beaglebone-black.

Written based on AM335x TRM.
