e92d56a94d Retrieve MD sysfs attributes for MD partitions
Rename private _primary_dev() to a public get_primary_dev() and reuse it
to allow retrieval of the MD sysfs attributes (raid level, etc) for MD
partitions.

bb2a46b218 Improve ability to lookup primary device associated with a partition
Improve lib/device/device.c:_primary_dev()'s ability to look up the
primary device associated with all partitions; including blkext
(e.g. partitions directly on MD).  The same will also work for obscure
sysfs paths; e.g.: paths with mangled names like the HP cciss driver
uses: /sys/block/cciss!c0d0/cciss!c0d0p1/

2aabcc1c1c Add devices/data_alignment_detection to lvm.conf.
Adds 'data_alignment_detection' config option to the devices section of
lvm.conf.  If your kernel provides topology information in sysfs (linux
>= 2.6.31) for the Physical Volume, the start of data area will be
aligned on a multiple of the ’minimum_io_size’ or ’optimal_io_size’
exposed in sysfs.

minimum_io_size is used if optimal_io_size is undefined (0).  If both
md_chunk_alignment and data_alignment_detection are enabled the result
of data_alignment_detection is used.

57b660356e Add devices/data_alignment_offset_detection to lvm.conf.
If the pvcreate --dataalignmentoffset option is not specified the start
of a PV's aligned data area will be shifted by the associated
'alignment_offset' exposed in sysfs (unless
devices/data_alignment_offset_detection is disabled in lvm.conf).

09a7dce6be Additional device-handling debug messages.
Additional verbosity level -vvvv includes line numbers and backtraces.
Verbose messages now go to stderr not stdout.

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.

e6efb2b0bd o got dbg_malloc_t working, Alasdair could you look at the Makefile.in it
seems to be having trouble with the dependencies.

o removed some files from the lib makefile that don't compile yet.
