AHCI registers (e.g. PxTFD.Status and PxTFD.Error).

Offet for the power control register was specified incorrectly (it had
the same value as the prefetch control register.) This change corrects
the offset value to 0xF80, per the ARM PL310 documentation.

This is done explicitly because a vcpu thread can be in a critical section
for the entire time slice alloted to it. This in turn can delay the handling

The function clearning credentials on failure asserts the process is a
zombie, which is not true when fork fails.
Changing creds to NULL is unnecessary, but is still being done for
consistency with other code.

building arm images. This is similar to tools/vmimage.subr
used for building virtual machine disk images. By default,
only arm_create_disk() and arm_install_base() contain real
functionality here, and arm_install_uboot() must be overridden
in the arm/KERNEL.conf file.
In release.sh, make create_arm_armv6_build_release() do
something now.
In arm/BEAGLEBONE.conf, set IMAGE_SIZE, PART_SCHEME, FAT_SIZE,
FAT_TYPE, and MD_ARGS, as well as make arm_install_uboot()
functional.
Parts of this were taken from disecting a previous BEAGLEBONE
image, and other parts obtained from Crochet sources.

Prior to this change both functions returned 0 for success, -1 for failure
and +1 to indicate that an exception was injected into the guest.
The numerical value of ERESTART also happens to be -1 so when these functions
returned -1 it had to be translated to a positive errno value to prevent the
VM_RUN ioctl from being inadvertently restarted. This made it easy to introduce
bugs when writing emulation code.
Fix this by adding an 'int *guest_fault' parameter and setting it to '1' if
an exception was delivered to the guest. The return value is 0 or EFAULT so
no additional translation is needed.

The requirement is for a GCC-compatible compiler and not necessarily
GCC itself. However, we currently expect any compiler used for building
the whole of FreeBSD to be GCC-compatible and many things will break if
not; there's no longer a need to have an explicit test for this in rtld.
