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

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.

291ec3b6c0 o Filter for the dev cache that takes values from config file:
devices {

        # first match is final, eg.  /dev/ide/cdrom
		        # get's rejected due to the first pattern

					filter=["r/cdrom/",         # don't touch the music !
							"a/hd[a-d][0-9]+/",
							"a/ide/",
							"a/sd/",
							"a/md/",
							"a|loop/[0-9]+|", # accept devfs style loop back
							"r/loop/",        # and reject old style
							"a/dasd/",
							"a/dac960/",
							"a/nbd/",
							"a/ida/",
							"a/cciss/",
							"a/ubd/",
							"r/.*/"] # reject all others
}


Alasdair this is ready to roll into the tools now.

d1b28647ed o First pass at the regex code. lib/regex/matcher takes an array of regex's
and builds a *very* efficient engine that will tell you which regex a string
  matches with only a single pass through the string.  To be used in the config
  file when specifying devices.

o Anchor's aren't supported yet (^ and $) but that won't take long.

o Also when we get some realistic config files we may want to consider adding an
  extra level of indirection to the dfa state in order to compress the table.
  It all depends on how large typical tables get.
