Clarify terminology:
...
VG is resizeable - PVs can be added or removed
PV is allocatable - free extents on it may be allocated to LVs

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.

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.

o if NDEBUG is not defined the dev_cache will check for open devices on
teardown.
I was hoping this would speed things up. But I'm still getting:
