Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.
These two new copies are still intact copies of disklabel.h and
therefore protected by #ifndef _SYS_DISKLABEL_H_ so #including them
in programs which already include <sys.disklabel.h> is currently a
no-op.
This commit adds a number of such #includes.
Once I have verified that I have fixed all the places which need fixing,
I will commit the updated versions of the three #include files.

argument. Leave a compatibility shim for Delete_Chunk().
Implement DELCHUNK_RECOVER flag so sysinstall can ask libdisk
to recover space when deleting a chunk.
sysinstall will automatically expand the previous partition to take up
the freed up space. So you can 'D'elete /home and /usr will get the
combined space, or you can 'D'elete /tmp and /var will get the combined space.
This gives the user, developer, or lay person a huge amount of flexibility
in constructing partitions from an 'A'uto base. It takes only 3 or 4
keystrokes to achieve virtually any combination of having or not having
a /tmp and/or /home after doing an 'A'uto create.
Change 'A'uto creation of /var/tmp to 'A'uto creation /tmp, which should
be less controversial.

if and only if a target directory is devfs. Previous patch
doesn't correct, it's unconditionally avoid to create a device
file if kernel knows devfs.

+ make Open_Disk sense the sector size by trying 512, 1024 and 2048
in this order. This makes the kernel note that
dscheck(cd1): bio_bcount 512 is not on a sector boundary (ssize 2048)
dscheck(cd1): bio_bcount 1024 is not on a sector boundary (ssize 2048)
if 2048 is the sector size. If this worries anyone: the message is from
/usr/src/sys/kern/subr_diskslice.c and shutups are to be placed there.
+ Have read_block and write_block use an additional parameter, the
sector size.
+ replace all barfout calls with return NULL, 0, __LINE__, etc.
Note that this does NOT emit diagnostics. More often than not,
you don't want library functions to scribble on stderr -- it may
not even be available. The right thing is to propagate the error
condition to upper management. The app should take care of errors.
+ use d1->sector_size instead of 512 in various places. I've left many
places untouched, especially those writing MBRs. I simply added
another arg hardcoded as 512. This is because I would not know what
I'm doing... I felt this approach would be reasonably backward
compatible and not introduce any new bugs in critical software.
Famous last words. Messing with MBRs might soon put me in the same
screwup meister category as, uh, never mind. :-)
+ bump the max no of disks from 20 to 32 (due to PR 24503).

Also, looking to the future, don't assume all the world is an i386 and all
its disk layout brain damage will be repeated by other platforms. So all
the diking out if we are an Alpha, becomes adding in if we are an i386.
`err()'). libdisk does! and additionally libdisk gets confused on Alpha
disks with foreign disklabels, throws up its hands and exits. This is
the cause of the "going no where without my init" install bug on the Alpha.
So now on the Alpha, rather than call err(), we print the error string and
continue processing.

present, this is limited to turning on the packet option if any of
disk slices begin above cylinder 1023. The effect of this change
should therefore be to automatically enable LBA support, as needed,
when installing FreeBSD.

with fdisk, ensure that they are a multiple of the sector size in length.
- Axe all the 1024 cylinder checks as they are no longer relevant with the
fixed bootstrap.
available. If not, it falls back to the existing hack and slash method.
A positive side effect is that non-root users may now use Disk_Names(),
for non-dangerous libh/disk.tcl testing.
