5bcbeca8e7 Fix pvmove allocation to take existing parallel stripes into account.
When moving parts of striped LVs, pvmove wouldn't care about leaving you with
two stripes on the same disk.  Now --alloc anywhere is needed for that.
(Tried and gave up on two alternative approaches before the one committed here.)

0802006ea7 Fix all segments memory is allocated from vg private mempool.
Physical segments were still allocated from global
command context mempool.

This leads to very high memory usage when
activating large VG (vgchange).
(Memory usage was about 2G when >3000LVs).

Fix it by properly using vg->vgmem private pool,
so all the memory is released early.

New memory pool parameter is needed here for pv_split_segment
function.

Also fix the same problem in some minor allocations
(vg description, lv segment split).

dd2157534b Default stripesize 64k & config file setting for it;
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

63875e7591 Merge with text format branch.
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.

0092790c7d 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.
