aaf8e1867b Allow to specify only one disk. This is helpful when we want to extend
our concatenated device later.

5bb84bc84b Normalize a significant number of kernel malloc type names:
- Prefer '_' to ' ', as it results in more easily parsed results in
  memory monitoring tools such as vmstat.

- Remove punctuation that is incompatible with using memory type names
  as file names, such as '/' characters.

- Disambiguate some collisions by adding subsystem prefixes to some
  memory types.

- Generally prefer lower case to upper case.

- If the same type is defined in multiple architecture directories,
  attempt to use the same name in additional cases.

Not all instances were caught in this change, so more work is required to
finish this conversion.  Similar changes are required for UMA zone names.

0499edf459 Before calling g_orphan_provider(), add G_PF_WITHER flag, so GEOM will know
to destroy it.

7e0b3120e7 - Add a missing g_io_deliver() in case of allocation failure - we didn't
completed I/O requests here.
- First allocate all needed bios, so if any of allocations fail, we can
  free memory before sending any I/O requests down.

e68909854c - 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.

201dfcf143 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.

6c74f5177c - Introduce option for hardcoding providers' names into metadata.
It allows to fix problems when last provider's sector is shared between few
  providers.
- Bump version number for CONCAT and STRIPE and add code for backward
  compatibility.
- Do not bump version number of MIRROR, as it wasn't officially introduced yet.
  Even if someone started to play with it, there is no big deal, because
  wrong MD5 sum of metadata will deny those providers.
- Update manual pages.
- Add version history to g_(stripe|concat).h files.

7e72a70863 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.

f1f163e9cb - Don't check if 'gp' is non-NULL, it always is and GEOM wants to
dump geom configuration when 'pp' and 'cp' are NULL.

48fbd94b4e - Don't take sectorsize from first disk. Calculate it by finding
least common multiple of all disks sector sizes.
  This will allow to safely concatenate disks with different sector sizes.
- Mark unused function arguments.
- Other minor cleanups.

0e2ff2832c Even if we're sure that we can't be orphaned here, we have to define
orphan field - we're enforcing it in GEOM. This will reach KASSERT
in INVARIANTS case.

Add missing space.
