511a5f3ad8 Add test for memory allocation failures 
Replace asserts with test for failing memory allocation.
Add at least stack traces.
Index counter starts from 1 (0 reserved for error), so replacing fingerprint.

6e41729eb8 Keep a global (per-format) orphan_vg and keep any and all orphan PVs linked to 
it. Avoids the need for FMT_INSTANCE_PV and enables further simplifications. No
functional change, internal refactor only.

8e5f7cf3dc Move lvmcache data structures behind an API (making the structures private to 
lvmcache.c). No functional change.

b93c1332d1 Move label_init up in code stack 
label_exit() is called destroy_toolcontext() and we are now
using standard dm_list function for destroy, we have to make sure
dm_list gets initialized properly.

94f88a4f14 Fix test for lv_snapshot_percent 
Do not check for PERCENT_MERGE_FAILED if the lv_snapshot_percent() failed.
(test for snap_percent would be testing uninitialized value).

462835faa0 Switch to return void 
List delete cannot fail, so there is no reason to test for error.

33dea28e23 Use dm_snprintf and improve error handling 
Add standard error reporting with error logging.
Use plain alloc instead of zalloc for string buffer.
Use dm_snprintf with valid test for <0.

eae8784ae2 Remove duplicate test 
Tested condition has been already evaluated before
For strlen() code has already excluded <ID_LEN.
For repairing, already tested (!argc && !repairing) before.

d75c5f06f0 Replace snprintf with dm_snprintf 
snprintf testing for negative is replaced with dm_snprintf where this
test really works.
Add missing test for result of dm_snprintf().

84fd8ea4bd Move done jump lower 
Since before 'goto done' is bufused zeroed, it would otherwise write 1
byte in front of buffer.

b63b775143 Add boundary test for number of mirror devs and logs 
As atoi may return negative value - test for both limits.
Test log_args for limits before calling alloca().
Code from dmeventd mirror plugin should probably share same code as
we have in mirrored.c.

ebc9abf6c0 Set all parameters to 0 
Since the function dm_get_next_target() returns NULL as 'next' pointer
so it's not a 'real' error - set 0 to all parameters when NULL is
returned because of missing head.

i.e. one of use case::
do {
	next = dm_get_next_target(dmt, next, &start, &length,
				  &target_type, &params);
	size += length;
} while (next);

1a39fa0073 Move close few lines 
Since the function dev_close() has code path, which really could close
file (for unlocked vg) and destroy dev handler, stay on safe side and move
the close few lines later, even our current use case shouldn't trigger
such scenario.

cd4c26a27f Set status for error path

when the function returns error.

ab852ffe66 Disable partial activation for thin LVs and LVs with all missing segments 
Count number of error and existing areas and if there is no existing area
for the LV avoid its activation.

Always disable partial activatio for thin volumes.

For mirrors currently put in hack to let it pass with a special name
since current mirror code needs to activate such LV during some operations.
