7f8badfe5e Use memcpy and add error message 
strncpy (which check each byte for \0) is not need as we always copy
the length size - so using memcpy is a bit cheaper.

Add missing log_error message for failed allocation.

f7e7f3e3ed Add checks for allocation errors in config node clonning. 
Add checks for clonning allocation a fail-out when something is
not allocated correctly.

Also move var declaration to the begining of the function
and fix log_error messages.

760d1fac55 Add more strict const pointers around config tree 
To have better control were the config tree could be modified use more
const pointers and very carefully downcast them back to non-const
(for config tree merge).

9085c301e0 Rename _override_settings into override_config_tree_from_string and move.

25497e2fa5 Fix confusing metadata syntax error messages. 
If there is syntax error in metadata, it now prints messages
like:
  Couldn't read 'start_extent' for segment 'extent_count'.
  Couldn't read all logical volumes for volume group vg_test.

The segment specification is wrong and confusing.

Patch fixes it by introducing "parent" member in config_node which
points to parent section and config_parent_name function, which
provides pointer to node section name.

Also it adds several LV references where possible.

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.
