Align and round the partitionable disk space to 4K by default.
Since this would also apply when recovering, make sure not to
align or round when that would have a partition fall outside
the partitionable area.

find: Correctly propagate -exec/-execdir ... {} + exit status.

As per POSIX, the -exec ... {} + primary always returns true, but a non-zero
exit status causes find to return a non-zero exit status itself. GNU does
the same, and also for -execdir ... {} +.

It does not make much sense to return false from the primary only when the
child process happens to be run.

The behaviour for -exec/-execdir ... ; remains unchanged: the primary
returns true or false depending on the exit status, and find's exit status
is unaffected.
Hide internal details of sbintime_t implementation wrapping INT64_MAX into
SBT_MAX, to make it more robust in case internal type representation will
change in the future. All the consumers were migrated to SBT_MAX and
every new consumer (if any) should from now use this interface.

Fix the style of ata_interrupt_locked().
Add a simple EFI stub loader. This is a quick and dirty of boot1.chrp from
the PowerPC port with all the Open Firmware bits removed and replaced by
their EFI counterparts. On the whole, I think I prefer Open Firmware.

This code is supposed to be an immutable shim that sits on the EFI system
partition, loads /boot/loader.efi from UFS and tells the real loader what
disk/partition to look at. It finds the UFS root partition by the somewhat
braindead approach of picking the first UFS partition it can find. Better
approaches are called for, but this works for now. This shim loader will
also be useful for secure boot in the future, which will require some
rearchitecture.
Fix a panic in zfs_rename().
this is due to a wrong dereference of a vnode when it's not locked and
can be (potentially) recycled. 'sdvp' cannot be locked on zfs_rename()
entry point because the VFS can't be sure that this scenario is
LOR-free (it might violate the parent->child lock acquisition rule).
Dereference 'tdvp' instead, which is already locked on entry, and access
'sdvp' fields only when it's safe, i.e. under ZFS_ENTER scope.

While at it, remove the usage of VOP_REALVP, as long as this is a NOP
on FreeBSD.

Determine whether to build clang and its bootstrap tools the same
way. This allows a clang bootstrap to happen, even when WITHOUT_CLANG
is defined. This is a minimal version of a more extensive change which
can be MFC'd more easily. However, we have to also test to see if
we're building clang as not cc, since the bootstrap for that needs
these cross tools and it is easier to build them in just one place.

Up the minimum system to build FreeBSD current to 8.0-RELEASE. The
issues with vendors that needed 7.x support have been resolved. Many
vendors are still using 8.x build platforms, however, so bumping this
up to 9.0 will have to wait until that is resolved. Actual support for
building from 8.x still relies on those vendors fixing bugs that are
present as most developers have moved onto 9.x or newer platforms.

Don't apply ctf conversions in POSIX mode. These can't happen there
because they pollute the POSIX environment, which doens't allow
for these extentions. ctf conversions are really only relevant when
used in coordination with the rest of the bsd*.mk system anyway.
Leave them in place for the normal, non-posix enviornment since
they are quite useful there.
