MFC EFI support for the installer

r264978 (nwhitehorn):

Add EFI support to the installer. This requires that the kernel
provide a sysctl to determine what firmware is in use. This sysctl
does not exist yet, so the following blocks are in front of the
wheels:
- I've provisionally called this "hw.platform" after the equivalent
thing on PPC
- The logic to check the sysctl is short-circuited to always choose
BIOS. There's a comment in the top of the file about how to turn
this off.

If IA64 acquired a boot1.efifat-like thing (probably with very few
modifications), the same code could be adapted there.

r265016 (nwhitehorn):

Finish connecting up installer UEFI support. If the kernel was
booted using EFI, set up the disks for an EFI system. If booted from
BIOS/CSM, set up for BIOS.

r268256 (nwhitehorn):

After EFI support was added to the installer, it needed to allow
boot partitions of types other than "freebsd-boot" (in particular,
"efi"). This allows the removal of some nasty hacks for supporting
PowerPC systems, in particular aliasing freebsd-boot to apple-boot
on APM and an IBM-specific code on MBR.

This changes the installer to use the correct names, which also
breaks a degeneracy in the meaning of "freebsd-boot" that allows the
addition of support for some newer IBM systems that can boot from
GPT in addition to MBR. Since I have no idea how to detect which
those systems are, leave the default on IBM PPC systems as MBR for
now.

Fix bindings of keys when in the partition editor. By adding the usual input binding to the "partlist" sub window.
This is a workaround, as for unknown yet reason the keys binded on the Partition Edition window are the one from partlist instead of the one from standard "formfield"

Add some missing DPADD.

Improve error handling and remove an unnecessary check on geom provider
type. GEOM provider names can't duplicate (or shouldn't -- devfs will either
break or only use the first one if they do) so using the first provider
by that name is a sufficient check. This also lets the scripted partitioner
install onto gmirror and geli and such things.

If no partition configuration is specified in {}, use the automatic setup
the interactive installer uses.

Example: bsdinstall scriptedpart ada0
Result: Use entire disk for a FreeBSD system with default partition layout

Add a simple scripted partitioner. Documentation and more scripting support
will come soon. This lets the install process have a line like:

bsdinstall scriptedpart 'ada0 GPT {1.5G freebsd-ufs /, 10G freebsd-swap,
auto freebsd-ufs /usr}'

to set up a system with a 1.5GB /, some swap space, and a /usr using the
rest of ada0.

Only validate the partition setup when the user presses "Save". If the user

call them and anyone unknown "Disk" instead of SCSI disk.

The PC98 gpart module supports labels now.

Import bsdinstall. This is meant to be (eventually in conjunction with
pc-sysinstall) a replacement for sysinstall in the 9.0 release and beyond.
Currently supported platforms are sparc64, pc98, i386, amd64, powerpc, and
powerpc64. Integration into the build system will occur in the coming
weeks.

Merging with pc-sysinstall will use this code as a frontend, while
temporarily retaining the interactive partition editor here. This work
will be done in parallel with improvements on this code and release
integration.

Thanks to all who have provided testing and comments!
