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.

9b30dfb967 Use const char * for name and old_name in vg
Switch to use const char pointers to avoid changes of these structure
members and having better control over, were these members could
be modified.

9d9de35dca Remove const usage from destroy callbacks
As const segment_type or const format_type are never released
use their non-const version and remove const downcast from dm_free calls.
This change fixes many gcc warnings we were getting from them.

303923fbf1 Use const char* const * for dm_regex_create()
Change API interface to accept even completely const array patterns.

This should present no change for libdm users and allows to pass
pattern arrays without cast to const char **.

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).

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.

2955b913ea Use new status code from fsadm check
Patch updates exec_cmd() and adds 3rd parameter with pointer for

If the passed pointer is NULL, behavior is unmodified.

Patch allows to confinue with lvresize if the failure from fsadm check is
caused by mounted filesystem as many of filesystem resize tools do support
online filesystem resize. (originally user had to use flag '-n' to bypass
this filesystem check)
