f0f43bc093 Misc cleanups in the new mlock code, incl. improving some variable names
& messages; using more statics (for now) to avoid redundant
recalculation; validating config file just once on loading; keeping maps
file open.

26ade5f27e Unconditionaly ignore also Virtual Dynamically-linked Shared Object
(VDSO on 32bit is VSyscall on 64bit)
It seems it could be locked on 64bit kernels running 32bit binaries,
but it makes troubles on real 32bit machines where mlock() returns
error when trying to lock such map area. (0xffffe000)
Behavior of mlockall() seems to be similar.

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.)
Default compilation has optimisation - or else use ./configure --enable-debug

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.
