902aecab13 Add a "header" subcommand that displays information about the size of 
the disk along with information from the GPT header if it exists.

733f23562f A change to the GPT_TYPE list also requires a change to the GPT_TYPE

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.

directly uses the disk ioctl's instead of relying on the drvctl device driver
which is currently not mandatory.

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.)

1029f7d668 include <sys/endian.h> for both the non-tools build, 
and the tools build on a host where the file exists.

Fixes a build problem on FreeBSD, reported by Herbert J. Skuhra, where
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.

06190c9314 Initial cut of gpt restore. This functions correctly in testing, 
but isn't all that pretty.  It has minimal error testing and may
leak memory.  It also only works with empty disks.  If passed "-F"
flag, it will blank the disk for you.

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.
