Alasdair Kergon
4a624ca055 o ACTIVE is no longer a status flag - lv_active() used to check if an LV
is active in the device-mapper.
o Many operations can be carried out regardless of whether the VG is
  active or not.
o vgscan does not activate anything - use vgchange.
o Change lvrename to support renaming of active LVs.
o Remove '//' appearing in some pathnames.
o Dummy lv_check_segments() for compilation.

faa556e759 Add internal cache holding a 'hint' list of the PVs belonging to each VG.
A substantial speed-up - particularly in readline mode.
If the hints turn out to be wrong, the relevant parts get thrown away.
vgscan destroys it totally.  In both cases it then rebuilds itself as
required.

f4a7ce7c49 - Change label format to include a string disk_type and a version number.
- The iterator can find labels by string and also appropriate version number (==,
  <= or any) if you want.
- Add labels_match() call that compares the two labels and returns an error if
  they do not match.
- Write labels in sector 1 & last rather than 2 & last as per Joe.

488a58a998 o Striped allocator
o  Changed pv_map.c to maintain the list of free areas in size order, which
   is more helpful to the allocators.  If you want to allocate a bit of an
   area call consume_area(area, size), this will adjust the area if there's
   some space left and shuffle it to the correct place in the list.


Not tested.

4a8d120415 o pool-debug.c contains an alternative implementation of pool that gets
a seperate chunk of memory from dbg_malloc for each pool_alloc.  This
   will allow the bounds checking code in dbg_malloc to do it's stuff.

o  The normal implementation moved to pool-fast.c

o  pool.c now just contains a #ifdef and includes the appropriate .c file.

Alasdair, could you make sure that gcc -MM get's passed all the
CFLAGS please, otherwise the dependencies get calculated incorrectly.

0bab65915d o Sync up todays work on converting to the segmented representation of
logical volumes.  It includes:

   format1 changes.

   metadata.h changes.

   lv_manip.c changed (striped allocation still not done though).

   activate.c changes.

Nothing has been near a compiler as yet.

Alasdair can you look at changing display.c to use to output the mappings
in a more segment oriented format please ?

I haven't put the span list into struct physical_volume to represent allocated
extents.  I think the burden of maintaining it for things like lv_extend may
out weigh it's uses.
