- Check for SMAP data from the loader first. If it exists, don't bother
doing any VM86 calls at all. This will be more friendly for non-BIOS
boot environments such as EFI, etc.
- Move the base memory setup into a new basemem_setup() routine instead
of duplicating it.
- Simplify the XEN case by removing all of the VM86/SMAP parsing code rather
than just jumping over it.
- Adjust some comments to better explain the code flow.

The previous version of code have no locking when testing rt_refcnt.
The result of the lack of locking may result in a condition where
a routing entry have a reference count but at the same time have
RTPRF_OURS bit set and an expiration timer. These would eventually
lead to a panic:
panic: rtqkill route really not free
When the system have ICMP redirects accepted from local gateway
in a moderate frequency, for instance.
Commit this workaround for now until we have some better solution.

- Teach gptboot and gptzfsboot about new files. I haven't touched the
rest, but there is still a lot of code duplication to be removed.
- Implement full GPT support. Currently we just read primary header and
partition table and don't care about checksums, etc. After this change we
verify checksums of primary header and primary partition table and if
there is a problem we fall back to backup header and backup partition
table.
- Clean up most messages to use prefix of boot program, so in case of an
error we know where the error comes from, eg.:
gptboot: unable to read primary GPT header
- If we can't boot, print boot prompt only once and not every five
seconds.
- Honour newly added GPT attributes:
bootme - this is bootable partition
bootonce - try to boot from this partition only once
bootfailed - we failed to boot from this partition
- Change boot order of gptboot to the following:
1. Try to boot from all the partitions that have both 'bootme'
and 'bootonce' attributes one by one.
2. Try to boot from all the partitions that have only 'bootme'
attribute one by one.
3. If there are no partitions with 'bootme' attribute, boot from
the first UFS partition.
- The 'bootonce' functionality is implemented in the following way:
1. Walk through all the partitions and when 'bootonce'
attribute is found without 'bootme' attribute, remove
'bootonce' attribute and set 'bootfailed' attribute.
'bootonce' attribute alone means that we tried to boot from
this partition, but boot failed after leaving gptboot and
machine was restarted.
2. Find partition with both 'bootme' and 'bootonce' attributes.
3. Remove 'bootme' attribute.
4. Try to execute /boot/loader or /boot/kernel/kernel from that
partition. If succeeded we stop here.
5. If execution failed, remove 'bootonce' and set 'bootfailed'.
6. Go to 2.
If whole boot succeeded there is new /etc/rc.d/gptboot script coming
that will log all partitions that we failed to boot from (the ones with
'bootfailed' attribute) and will remove this attribute. It will also
find partition with 'bootonce' attribute - this is the partition we
booted from successfully. The script will log success and remove the
attribute.
All the GPT updates we do here goes to both primary and backup GPT if
they are valid. We don't touch headers or partition tables when
checksum doesn't match.

According to wikipedia Microsoft TechNet says that attributes are divided into
two halves: the lower 4 bytes representing partition independent attributes,
and the upper 4 bytes are partition type dependent. Microsoft is already using
bits 60 (read-only), 62 (hidden) and 63 (do not automount) and I'd like to not
collide with those, so we are using bit 59 (bootme), 58 (bootonce) and 57
(bootfailed).
