18b82048e4 mlockall() -> mlock()
This patch adds a new implementation of locking function instead
of mlockall() that may lock way too much memory (>100MB).
New function instead uses mlock() system call and selectively locks
memory areas from /proc/self/maps trying to avoid locking areas
unused during lock-ed state.

Patch also adds struct cmd_context to all memlock() calls to have
access to configuration.

For backward compatibility functionality of mlockall()
is preserved with "activation/use_mlockall" flag.

As a simple check, locking and unlocking counts the amount of memory
and compares whether values are matching.

8ef2b021ed 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.)

b9923fe3f2 Make lvm2 compile on big endian archs; use the kernel/glibc's endian
conversion stuff, instead of implementing our own.  Tested on a little
endian system (x86); I'll let the debian handle big endian testing.  :)

25b733809a 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.

4b2ec1929a o There were some alignment problems with pool-debug which I've resolved
by allocating the data block with an additional dbg_malloc.

o  Added an assertion to check that no one is requesting alternate
   alignment for memory allocated from pool.  I can't see us needing this
   for LVM2.

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.

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.
