Cow may not be a COW type, the return value of origin_from_cow(cow) may be NULL.

463a61e62e revert "lvconvert: check if LV has snapshot type"
This reverts commit 7db124774a.
Actually we need to check for lv_is_cow().

77fdc17d70 alloc: improve estimation of sufficient_pes_free
Metadata size was calculated correctly only for raids.

Fixes problem for crash during lvcreate when thin-pool was created
on a VG where remaining free space had the size to only fit a single
metadata LV and not also its _pmspare.

Lvcreate crashed with this assert message:

lvcreate: metadata/pv_map.c:198: consume_pv_area: Assertion `to_go <= pva->count' failed.
Aborted (core dumped)

TODO: there is probably to large overload of several alloc_handle
variables.

d71199920f pvmove: check return value of top_level_lv_name()
The return value of top_level_lv_name() may be NULL, so we should
check return value of top_level_lv_name before calling
strcmp(lv->name, top_level_lv_name(vg, lv_name)).

c38c4d9d36 gitignore: ignore all cscope generated files
When using cscope to read code, it will generate below 3 files for speedup
cross-refer: cscope.files, cscope.in.out, cscope.po.out

The .gitignore only contains "/cscope.out". It a little bit messy when
executing 'git status', and other git commands.
This patch add all cscope generated files in .gitignore.

9f78acfee9 thin: compensate metadata size by extra percent
When using --use-policy for automatic extension of thin-pool,
the extension of thin-pool's metadata itself can actually take
some extra space.
Since I'm not aware of exact compensation formula, add just
1% extra to calculated amount and hope it fits.

Wanted target is to always have usable thin-pool that fits
bellow pool_metadata_min_threshold().

e7bd3ba22d debug: drop debug trace from regular path
Since we query on regular code these:
  lv_raid_has_integrity()
  lv_has_integrity_recalculate_metadata()
without prior checking for lv_is_raid() - these 'return 0' should
not use <stacktrace> as they are expected.

ce5ea07411 raid: do not enforce flushing of raids when it is not required
This is probably somewhat experimantal patch - but when i.e. raid device
is just extend, there should not be a technical need for flush,
unless the target would stricly need it.  It should allow faster
processing of lvm command not being blocked by possibly longer flush.

3388e19489 raid: add _rimage and _rmeta as origin_only
Since we do not support rimage & rmeta for snapshots - we can
avoid quering for -cow devices and add them as origin_only -
since their snapshots (-cow) could have never existed.
This redumes several ioctl operation during table preloading.

76b1f43e81 tests: add aux delayzero_dev support
Just like we have 'writeerror_dev' supporting creation of device
which 'readable' segment and segments where write will fail we
have now support for delay zero mappings.

This is useful if we want to 'fake' large writing areas where we do
not really care about the actual 'disk' content - since we test
operation logic and it doesn't matter we read and write zeroes.
With combination with 'delay' target we can create specific mappings
and avoid using large memory areas of ramdisk.
