5467a3b2b7 filters: update composable filter 
Last commit made dump filter only partially composable.
Add remaining functionality and also support composable wipe,
which is needed, when i.e. vgscan needs to remove cache.

(in release fix)

e7878da921 filters: toplevel filter not persistent 
Add a generic dump operation to filters and make the composite filter call
through to its components. Previously, when global filter was set, the code
would treat the toplevel composite filter's private area as if it belonged a
persistent filter, trying to write nonsense into a non-sensical file.
Also deal with NULL cmd->filter gracefully.

c7b17836ea Implement devices/global_filter. 
The global filter is applied first, and is also applied in pvscan --cache (which
is called from udev rules to keep lvmetad updated). Cf. example.conf.

0d3ce181e1 Better structure layout for device_info 
Save some relocation entries and use directly char[].
Since we do not need yes more then 127 partitions per device, use just int8_t.
Move lvm_type_filter_destroy into local static function.

edcda01a1e Obtain device list from udev by default if LVM2 is compiled with udev support. 
Also, add a new 'obtain_device_list_from_udev' setting to lvm.conf with which
we can turn this feature on or off if needed.

If set, the cache of block device nodes with all associated symlinks
will be constructed out of the existing udev database content.
This avoids using and opening any inapplicable non-block devices or
subdirectories found in the device directory. This setting is applied
to udev-managed device directory only, other directories will be scanned
fully. LVM2 needs to be compiled with udev support for this setting to
take effect. N.B. Any device node or symlink not managed by udev in
udev directory will be ignored with this setting on.

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

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.
