This fixes sysinstall, now that geom_part has taken over from
geom_gpt.

Previously, any parse error will result in the calling program exiting with an
unpleasant message. This change will cause libdisk to issue a warning and
ignore lines it cannot parse instead of bluntly terminating the unfortunate
enough program.
This change will allow you to use sysinstall if you have a NTFS parition with
a space in the name (such as 'Win Xp'). In such a case, a line like the
following will appear in the kern.geom.conftxt output:
2 LABEL ntfs/Win Xp 209818635264 512 i 0 o 0
As the fields are space-separated, libdisk would go beserk and exit the program.
This would happen if using FreeBSD 7.0 snapshot images (as GEOM_LABEL is in
the installation kernel as well), thus making it impossible to install FreeBSD
without renaming your NTFS paritions.

the GPT partition on i386 and adm64 as type=gpt, subtype=0 and with the
sname set to the UUID. This prevents sysinstall from bombing out. This
also makes sure the GPT partition shows up in sysinstall so as to avoid
accidental "clobberage".

the chunk will never be added to the list in that case. Use type mbr
for GPT nested MBRs and use type part for any partition we don't know
or care about. Since the subtype is 0, this should not cause confusion.

allows sysinstall to properly handle disks and filesystems > 1 TB.
Changes from the original patch include:
- Use d_addr_t rather than inventing a blkcnt type based on int64_t.
- Use strtoimax() rather than strtoull() to parse d_addr_t's from config
files.
- Use intmax_t casts and %jd rather than %llu to printf d_addr_t values.

MBR slices for non-GPT disks. Since most of the GPT handling is
conditionally compiled, do the same with the partition naming.
This fixes a braino that caused slices to be named as GPT partitions
and generally messing up an install.

better. In all cases we update the start and end LBAs.

o Pass the GEOM conftxt to Int_Open_Disk() so that only Open_Disk()

o Create an ia64 specific definiton of struct disk on ia64, because
we don't need/have most of the fields other platforms need and
other fields not applicable on platforms other than ia64.
o Do not compile change.c on ia64. It's too PC specific.
o In Fixup_Names() in create_chunk.c, try all partition numbers
that are valid for the GPT disk. We have the total number of
partitions that can be allocated in the disk structure on ia64.
Also, use the GPT partition naming if we're creating one under
a chunk of type "whole". It's a GPT partition in that case.
o In Create_Chunk(), compile-out the PC specific code on ia64 that
checks BIOS geometry restrictions.
o In Debug_Disk() in disk.c, dump the ia64 specific fields.
o Save the partition index in the chunk on ia64 so that we can
preserve it when we write the data back to disk. This avoids that
partitions get moved around or swapped after installing FreeBSD,
which may render a disk unusable.
