0e88dec738 Fix usage of readlink
Return value of readlink limits valid string size.
Characters after returned size present some garbage to printf.
Fix it by placing '\0' on the return size value.

f0e82e4473 Recognise and give preference to md device partitions (blkext major).
We can already detect MD devices internally. But when using MD partitions,
these have "block extended major" (blkext) assigned (259). Blkext major
is also used in general, so we need to check whether the original device
is an MD device actually.

2adec6ef66 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.

5829d87313 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/

4422423315 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.

6c88b6c660 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).

63875e7591 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.
