c23f4c8075 makefiles: add check for versioned symbols
Simple check produced library has the latest symbol as well as its versioned
older version with check for dm_stats_create_region().

40b277ae17 makefiles: slight change in .export.sym
Avoid emitting Local symbol and sort symbols from
start and add dependency on previous version
Should not change anything, just better followup
linkage guidlines.

1398e66a55 libdm: move dm_task_get_info_with_deferred_remove
Version is only needed for dm_task_get_info().
dm_task_get_info_with_deferred_remove() shall be compiled for
non-versioned library as well.

12949ea886 hints: don't use hints when --sysinit is used
Devices are not in a steady state during system init,
so hints are repeatedly invalidated, and hardly used,
so maintaining them is wasted effort.

1cedbaf137 configure: support builds without versioning
Not all libc (like musl, uclibc dietlibc) libraries support full symbol
version resolution in runtime like glibc.
Add support to not generate symbol versions when compiling against them.

Additionally libdevmapper.so was broken when compiled against
uclibc. Runtime linker loader caused calling dm_task_get_info_base()
function recursively, leading to segmentation fault.

Introduce --with-symvers=STYLE option, which allows to choose
between gnu and disabled symbol versioning. By default gnu symbol
versioning is used.
__GNUC__ check is replaced now with GNU_SYMVER.
Additionally ld version script is included only in
case of gnu option, which slightly reduces output size.

Providing --without-symvers to configure script when building against
uclibc library fixes segmentation fault error described above, due to
lack of several versions of the same symbol in libdevmapper.so
library.

37d603268f tests: for 4.18 use already 1.20 logic
Looks like there was some missed versioning increase during devel.
So with kernel >= 4.18 version 1.19 is enough to look like 1.20

However backported 1.19 targets seems to not provide all
the capabilities.

25c665d555 tests: dbus update
Always use  PREFIX for vg header - all tests must use this prefix,
VGs without are not allowed.

Modify pv_symlink test - as the test was checking unsupportable
combination - since lvm2 commands withing testsuite are only
allowed to manipulate with /dev/mapper/LVMTESTXXXX path -
nothing else allowed and fails on being filtered.

starts dmeventd if it's not running.

5feb99dda6 tests: add workaround for older mdadm
Some older instancies of 'mdadm' opened legs in RW and
closed and opened again and expected exlusive access.
But here udev rule can be fired - so on these versions
slow down whole mdadm runtime by using strace, to
give system a bit more time to finish udev rule.
