- Add md_provsize field to metadata, which will help with
shared-last-sector problem.
After this change, even if there is more than one provider with the same
last sector, the proper one will be chosen based on its size.
It still doesn't fix the 'c' partition problem (when da0s1 can be confused
with da0s1c) and situation when 'a' partition starts at offset 0
(then da0s1a can be confused with da0s1 and da0s1c). One can use '-h'
option there, when creating device or avoid sharing last sector.
Actually, when providers share the same last sector and their size is equal,
they provide exactly the same data, so the name (da0s1, da0s1a, da0s1c)
isn't important at all.
- Provide backward compatibility.
- Update copyright's year.

This is not needed anymore, it is forced in GEOM now.
Actually, it can even cause some problems, because GEOM requires sectorsize
to be more than 0 on first access, not on provider creation, so we can skip
valid providers by doing this check here.

Allow to configure debug level from /boot/loader.conf.

Skip providers with not defined sector size.

Reported by: kuriyama

Do not use g_wither_geom(9). I doesn't work in the way which is expected
here anymore (after g_wither_washer() was introduced), i.e. geom and consumer
will not be immediately destroyed if possible.

Tag all geom classes in the tree with a version number.

Decrease log level of one debug message, so there is no hole (level 2
wasn't used at all).

Add missing argument.

Properly free resources if g_access() fails.

- Add 'stop' command, which works just like 'destroy' command, but sounds
less dangerous.
- Update manual pages and extend examples.
- Bump versions.
