- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Merge the FDT versions of initarm.

The copies of initarm used on platforms with FDT support were almost
identical. The differences were pulled out into separate functions that
were called by initarm.

This change merges the, now identical, copies of initarm and a few of it's
support functions. This is a step towards a common kernel on ARMv6.

Merge r242125 into the other ARMv6 copies of initarm.

Pull out the SoC specific parts of initarm into separate functions

Update different versions of physmap_init to be identical in preparation
for merging them.

Reduce the diff between the FDT implementations of initarm.
This only touches whitespace and comments.

Create a common set_stackptrs in sys/arm/machdep.c.

On single core devices set_stackptrs is only ever called with cpu = 0 in
initarm and will be identical to the existing function. On SMP this needs
to be implemented for sys/arm/mp_machdep.c, but the implementations are
identical for each SoC.

Start to clean up ARMv6 initarm implementations by making the Tegra 2
version similar to the Ti version.

In the Tegra 2 standard config:
* Remove an unneeded makeoption
* Set machine correctly
* Properly indent the include of files.tegra2

The cpu_reset function is noreturn, make sure this is true on Tegra 2.
While here fix a typo.

Merging of projects/armv6, part 9

Very basic support for Nvidia Tegra2: timer, interrupts, UART.
