Add a GPT-aware variant of zfsboot which should be used in a similar manner to gptboot, i.e. installed in a freebsd-boot partition using /sbin/gpart or /sbin/gpt. Tweak the /boot/loader ZFS support so that it can find ZFS pools that are contained in GPT partitions.

Fix gptzfsboot for cases with GELI. HAVE_GPT isn't currently a thing, but HAVE_GELI is. Replace the former with the latter and remove util.o from the build list (it's picked up from libsa/libsa32, and that's OK). Sponsored by: Netflix

HAVE_GELI= yes
Move LOADER_{NO,}_GELI_SUPPORT to MK_LOADER_GELI Transition to WITH/WITHOUT_LOADER_GELI to flag support or not of GELI in the boot loaders. Add HAVE_GELI so components can flag they need support (since it's too large to include everywhere). Add temporary warnings for the old forms to ease transition. Also, update test script to build without GELI on x86. Sponsored by: Netflix

gpt/zfs boot blocks: reduce optimizing CFLAGS to -O1 gpt and zfs boot blocks are not nearly as size-constrained as boot2 from which they inherited their current optimization and anti-optimization options. As such the current options do not provide any benefit, but make debugging of the code much harder. Also, it has been demonstrated that combination of -mrtd and -fno-unit-at-a-time may result in mis-compilation of the boot code with the current base gcc. Additionally, intermediate assembly file filtering is removed for zfsboot. The new boot blocks are all compile- and boot- tested using qemu. gptzfsboot is tested with real hardware.

zfsbootcfg: a simple tool to set next boot (one time) options for zfsboot (gpt)zfsboot will read one-time boot directives from a special ZFS pool area. The area was previously described as "Boot Block Header", but currently it is know as Pad2, marked as reserved and is zeroed out on pool creation. The new code interprets data in this area, if any, using the same format as boot.config. The area is immediately wiped out. Failure to parse the directives results in a reboot right after the cleanup. Otherwise the boot sequence proceeds as usual. zfsbootcfg writes zfsboot arguments specified on its command line to the Pad2 area of a disk identified by vfs.zfs.boot.primary_pool and vfs.zfs.boot.primary_vdev kenv variables that are set by loader during boot. Please see the manual page for more. Thanks to all who reviewed, contributed and made suggestions! There are many potential improvements to the feature, please see the review for details.

Install the 4th files in sys/boot/forth instead of each loader Also, move generation of loader.help into loader.mk. Set HELP_FILES= to disable this (so we only install one help file, for now). At the same time remove some duplicate -I lines. Fix several FILES= and CLEANFILES= into the += form since we're touching both of those in the .mk files. Make sure we only build one loader.help file per platform in a unified way (we were building many on some, with the last to install winning, though often they were the same text). Also, we're now installing loader.rc and menu.rc everywhere. arm and mips uboot installed these as menu.rc.sample, but there's no need since the loader.rc for those platforms doesn't do menu.rc processing by default. pcibios.4th is now installed everywhere, but will failsafe on non x86 platforms (it isn't loaded by default anywhere).
