79b2961399 build: rename device-mapper to device_mapper
As Makefiles already do use target with name 'device-mapper'
rename this new device-mapper dir to non-conflicting name.
We also seem to already use '_' in other dir names.

Also rename device_mapper/Makefile to source for generating Makefile.in
so we can use it for build in other source dirs properly.

e2c766d37e build: fix build rules for srcdir
It's very hard to use some 'non-recurive' Makefiles with
rest of system running 'recursively'.

So ATM drop inclusion of subdir makefile and add support
for 2 new top-level targets:

unit-test  (builds test/unit dir)
run-unit-test (build & run test/unit/unit-test run)

0b465d1543 tests: drop cache checking
Just like 52656c89fd
when now cache is compiled in 'unditionally'.

This patch is actually enforce by changes in
commit: 2bc896f2a3
where CACHE value is not set anymore.

cbe81a0b05 tests: inittest may run without root
If the test does not need root, it can use 'SKIP_ROOT_DM_CHECK'.

For such test no actions needed root to initilize DM devices and
nodes will be take and test can check i.e. functional unit tests.

f5da325d70 tests: use throttle_dm_mirror
In this case it's better to use throttling of mirror sync,
that delay everything with dm_delay.

172d8fb355 tests: aux support throttling of dm mirror
Usage of dm_delay looks to be slowing not just 'delayed' portion
of device, but due to the fact it's also slows down ANY flush
operation on such device it's overal speed impact is huge.

In some case we can however user other methods to slowdown disk writes,
in case of old dm 'mirror'  target we can throttle  I/O of mirror
synchronisation giving the next commands enough time to test couple
race conditions.

Usage:

throttle_dm_mirror [percentage]

Thtrottle down sync speed (lowest is '1' which is also default when
unspecified)

restore_dm_mirror

Restores the value of throttling before call of  'throttle_dm_mirror'
Usually it should '100'

0cadfdd69d tests: try running tests over ramdisk
Currently usage of loop device over backend file in ramdisk (tmpfs)
is actually causing unnecassary memory consution, since just
reading such loop device is causing RAM provisioning.

This patch add another possible way how to use ramdisk directly
through 'brd' device when possible (and allowed).

This however has it's limitation as well -  brd does not support
TRIM, so the only way how to erase is to remove brd module ??

Alse there is 4K sector size limitation imposed by ramdisk.

Anyway - for some mirror test that were using large amount of
disk space (tens of MB) this brings noticable speed boost.
(But could be worth to solve the slowness of loop in kernel?)

To prevent using 'brd' for testing set LVM_TEST_PREFER_BRD=0
like this:

make check_local LVM_TEST_PREFER_BRD=0

842b3074b7 tests: crypt test cannot run on ramdisk
This test can't use brd (ramdisk) as backend since for some
weird reason  lsblk is not listing these device.

TODO: test could be probably rewritten to avoid using lsblk somehow??

6f48741062 tests: happy using of 4K backend devices
When the backend device supports only 4K blocks (like ramdisk)
we cannot use for testing any smaller blocksize.

So recalc test for 4K extent size.

We may possibly introduce one list extra test that
can be executed on devices with 512b sectors to
check lvm2 support those min extent sizes...

576dd1fc41 radix-tree: First drop of radix tree.
An implementation of an adaptive radix tree.  Has the following nice
properties:

  - At least as fast as the hash table
  - Uses less memory
  - You don't need to give an expected size when you create
  - It scales nicely (ie. no large reallocations like the hash table).
  - You can iterate the keys in lexicographical order.

Only insert and lookup are implemented so far.  Plus there's a lot
more performance to come.

4ebfd8e8eb lvconvert: don't return success on degraded -m raid1 conversion
In case "lvconvert -mN RaidLV" was used on a degraded
raid1 LV, success was returned instead of an error.

Provide message to inform about the need to repair first
before changing number of mirrors and exit with error.

Add new lvconvert-m-raid1-degraded.sh test.

c1cd18f21e Remove lvm1 and pool disk formats
There are likely more bits of code that can be removed,
e.g. lvm1/pool-specific bits of code that were identified
using FMT flags.

The vgconvert command can likely be reduced further.

The lvm1-specific config settings should probably have
some other fields set for proper deprecation.
