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).

bebfa29b48 Fix NULL pointer check for *buf
As ternary operator has lower priority then add operation, this check
was not doing what seemed to be expected.

So enclose the test in braces and check for NULL in *buf.

91106a4a2d Create /var/run/lvm directory during clvmd initialisation if missing.
We need to be sure that /var/run and /var/lock is always there.
(E.g. these two directories could be using tmpfs which then loose
all the content after reboot.)

7dfce0e467 Add new dm_prepare_selinux_context fn to libdevmapper and use it throughout.
Detect existence of new SELinux selabel interface during configure.
Use new dm_prepare_selinux_context instead of dm_set_selinux_context.

We should set the SELinux context before the actual file system object creation.
The new dm_prepare_selinux_context function sets this using the selabel_lookup
fn in conjuction with the setfscreatecon fn. If selinux/label.h interface
(that should be a part of the selinux library) is not found during configure,
we fallback to the original matchpathcon function instead.

acb037657c Fix scanning of VGs without in-PV mdas.
Set cmd->independent_metadata_areas if metadata/dirs or disk_areas in use.
- Identify and record this state.

Don't skip full scan when independent mdas are present even if memlock is set.
- Clusters and OOM aren't supported, so no problem doing the proper scans.

Avoid revalidating the label cache immediately after scanning.
- A simple optimisation.

Support scanning for a single VG in independent mdas.
- Not used by the fix but I left it in anyway as later patches might use it.

54fca7b1ca Remove reset of vg->vgmem pointer as it is access of already release memory
This reset of vgmem pointer causes access of already released memory.
(_vg_make_handle allocates vg from vgmem pool itself - which is a bit tricky)

Interestingly this memory fault was missed by our test suite.

21ba805499 Fix memory leak in error path
Nicely hidden memory leak in outf macro error path.
This macro is using out_text() and does automagical return_0.
That would leak tag_buffer allocated memory.

As there was same code for tags output - create _out_tags() function.
