29c769ab8c Instruct user to use resizedisk if media size has changed, as 
resizedisk will adjust the media size in the headers, whereas
recover simply copies the existing header over the missing one.

XXX recover and resizedisk should probably be merged (even if just
partially, so that recover can properly handle media size changes).
Also, reading in the GPT should probably be centralised so that
error handling can be centralised, and users aren't given misleading
messages (i.e. they aren't told to run recover when they should be
running resizedisk).  However, something that can be quickly pulled
up to netbsd-7 was needed, and there isn't time for a major overhaul
or rewrite.

ba983c7779 Make gpt(8) generate v4 (random) uuids. 
Don't needlessly leak your date/time and MAC address when you edit
the disk.

Read from /dev/urandom rather than calling arc4random or anything,
since this is a tool.  (Cygwin seems to have /dev/urandom, but yell
if this breaks the build on your exotic platform because it lacks
/dev/urandom.)

tools/compat's configure detected that be32dec() and friends were
available in the host's <sys/endian.h>, so tools/compat did not provide
its own versions.

e3f4016378 - dump all partitions, not just ones that are in use 
- while here, squash a memory leak

     It shouldn't be necessary to backup unused partitions, however
the partition GUID is created at the time the GPT is created and
is never changed.  It shouldn't matter if the GUID of an unused
partition changes, but there may be some special case where it
does.  Since it isn't a big deal to record the unused partitions,
might as well do it.

024b3f7622 Don't attempt to create/resize an unaligned partition if the attempt 
to create/resize an aligned one failed.  This simplifies the code
and prevents surprises.  If the user wants an unaligned partition
in the case where an aligned one fails, they can simply retry the
command without the "-a" option.  This change was requested by
wiz@, and after some thought I agree with it.

- s/-b number/-b blocknr/
- s/-s count/-s sectors/
- s/-p count/-p partitions/

In the program:
- s/-b lba/-b blocknr/
- s/-s lba/-s sectors/

This makes the documentation in the manpage and the program consistent
and makes it more clear what the parameters are.  Also, "-s lba" was
just plain wrong since LBA stands for Logical Block Address[ing], and
the -s option didn't represent any kind of address, but rather a size.
