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.

66781f5d5a Fix wrong cast to char*
As cmd->cmd_line is already const char pointer it's not needed to cast already
const char pointer to char pointer.

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).

0281405a4d Move var declarations to function begining
As assert macro jumps to 'bad:' label - we need vg initialized.

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.

5bd1cb414b Test lv_name is not NULL
Patch adds extra check for lv_name not being NULL.
Test avoids unneeded strlen call for this case.
Otherwise there is no functional change as test would fail on
size_t comparation even for NULL lv_name (thus there is no risk
of NULL dereference when taking 'true' if branch.

973db2a823 Test uuid for NULL
Add test for NULL before passing uuid as src argument to memcpy.
As memcpy function is declared as function not accepting NULL.

no functional change to the code.
