PR/55875 - Valentin -- "gpt recover -r" does nothing

Delete do nothing undocumented option, that was there from initial
import. No idea what it was intended to do and there is no longer
an "upstream".

Not all things that write to the disk do something that dk(4) will
be interested in. Let individual commands decide if ioctl(DIOCMWEDGES)
should be done. I was conservative and set the flag on any command
that might create/modify/delete partitions in any way.

branches: 1.17.10; 1.17.12;
Add missing endianes swap to make the "recover" command work on big endian
machines.

- fix setting of hdr_lba_alt which was broken in revision 1.10 on 2015/12/2
- switch to using gpt_last
- PR/51230 -- recreate the PMBR if it was lost

Fix resizedisk.

CID 1341556: Don't leak map info

WARNS=6

eliminate static globals so that commands can be re-used.

don't hard-code the program name

merge duplicated code and check allocations.

Refactor the command dispatching and help printing logic.

Firs step of refactoring, remove all globals, factor out some common code,
handle alternate usage but not advertise it.

merge the create errors in one place and fix them.

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.

minor toolification: need libprop...

branches: 1.4.20;
Use __dead

Fix the usage strings for each command, and print them all for the
"global" usage. It's still a little ugly, but hopefully not as
fantastically confusing as before...

branches: 1.2.2; 1.2.4; 1.2.8; 1.2.10;
Make this work under NetBSD.
