afe46c849b size_ts aren't really pointers but there are no format specifiers for them, 
so this will just have to do.

e55ae5d32e o lvcreate no longer needs the explicit -n flag

29aa6d5850 o Added dev_open and dev_close functions 
o  Changed disk-rep to use these

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:

reti:/home/joe/sistina/LVM2/tools# time ./lvm vgchange -a n
  Volume group vg0 successfully changed

real    0m5.751s
user    0m0.060s
sys     0m0.070s

even though I have only 1 device with the vg on it passing the filters.

12eabe3031 o composite filter that allows us to merge filters. Think of it as &&'ing 
filters in order.

eg,

	f = composite_filter_create(2, regex_filter, persistent_filter);

  ownership of the filters passes, they will be destroyed when f's
  destroy method is called.

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.
