- 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.

Add an END macro to ARM. This is mostly used to tell gas where the bounds
of the functions are when creating the EABI unwind tables.

Merging projects/armv6, part 1

Cummulative patch of changes that are not vendor-specific:
- ARMv6 and ARMv7 architecture support
- ARM SMP support
- VFP/Neon support
- ARM Generic Interrupt Controller driver
- Simplification of startup code for all platforms

Correctly return EFAULT in copyin & copyout on a fault. This fixes NFS
when running FreeBSD on QEMU emulating a Gumstix board.

While here remove the use of a magic number in the not-XScale version.

Do not use __XSCALE__ to detect if pld/strd/ldrd is available, use
_ARM_ARCH_5E instead.

MFC After: 3 days

Unbreak for !__XSCALE__.

Add a new API to let platform-specific ports provide functions for big
copy/zeroing.

Remove kcopy(), we don't use it.

Start all license statements with /*-

s/RETEQ/RETeq/.

Use the RET macro.

Use the right path for the bcopyinout_xscale.S file.

Import FreeBSD/arm kernel bits.
It only supports sa1110 (on simics) right now, but xscale support should come
soon.
