89d355ea04 configure: set DEFAULT_FALLBACK_TO_LVM1 in configure and use it in config_settings.h
Just like we have DEFAULT_USE_LVMETAD (or DEFUALT_USE_LVMPOLLD), use
fallback_to_lvm1=1 lvm.conf setting if we configured lvm2 with
--enable-lvm1-fallback and use fallback_to_lvm1=0 otherwise.

Also, generate proper lvm.conf.in with unconfigured value.

20e336f21c configure: add DEFAULT_USE_BLKID_WIPING
If blkid wiping is possible, than set use_blkid_wiping=1 and
use_blkid_wiping=0 otherwise for its default value. If blkid wiping
is disabled during configure and use_blkid_wiping=1 is set by chance,
it's simply ignored - this patch is just a cleanup that makes it more
obvious for the user (we use similar logic for use_lvmetad and
use_lvmpolld settings).

dc49e1cde0 configure: update localedir
Previous patch incorrectly skipped replace of @LOCALEDIR@.

The standard option is --localedir  so use --with-localedir
as backward compatible option and set localedir if it's not
yet been set (if the could ever happen).

Use double-eval to translate $datarootdir to $prefix to real dir.

797c18d543 libdm: new dm_task_get_info with internal_suspend
Introduce new implmentation of dm_task_get_info() function
with support for reading internal_suspend.
.
This time it is done in a 'versioned' way.

We keep the old fashion dm_task_get_info(Base) to implement
the old behavior of 1.02.95 libdm code.

libdm version 1.02.96 introduced 'macro' wrapper
dm_task_get_info_with_deferred_remove with new implementation
of dm_task_get_info() - we cannot do anything else then to
provide compatible version of this symbol.

Now in version 1.02.97 we add new versioned implementation of
dm_task_get_info(DM_1_02_97) symbol.

This has the effect that i.e. rpm build will finaly resolve proper
dependency on a new symbol - so it will be no longer possible,
to build a new binary and use old library
(rpm -q --provides will show libdevmapper.so.1.02(DM_1_02_97)(64bit))

Also the history is now tracked. If a new function is added (or
reimplemented), it needs to be placed in proper file,
so it could be exported with right versioning symbol.
File .exported_symbols.Base should and any existing older DM
should be treated as read-only after a release.

Also - only libdm has been currently enhanced with versioned .Base
file, as soon as other libs (liblvm, libdevmapper-event) needs changes
they should also get their exported symbol files - meanwhile
make.tmpl handles both cases.

Configure provides proper settings for
use_lvmetad  and use_lvmpolld  conf setttings.

When the build of polld & lvmetad, these settings
are enabled by default unless explicitelly disabled
with --disable-use-lvmetad/--disable-use-lvmpolld.

1c7a509bed filters: add firmware RAID filter
Just like MD filtering that detects components of software RAID (md),
add detection for firmware RAID.

We're not adding any native code to detect this - there are lots of
firmware RAIDs out there which is just out of LVM scope. However,
with current changes with which we're able to get device info from
external sources (e.g. external_device_info_source="udev"), we can
do this easily if the external device status source has this kind
of information - which is the case of "udev" source where the results
of blkid scans are stored.

This detection should cover all firmware RAIDs that blkid can detect and
which are identified as:
  ID_FS_TYPE = {adaptec,ddf,hpt45x,hpt37x,isw,jmicron,lsi_mega,nvidia,promise_fasttrack,silicon_medley,via}_raid_member

snapshots if needed.

7cff640d9a activation: Fix upgrades using uuid suffixes.
2.02.106 added suffixes to some LV uuids in the kernel.

If any of these LVs is activated with 2.02.105 or earlier,
and then a later version is used, the LVs appear invisible and
activation commands fail.

The code now has to check the kernel for both old and new uuids.

5abdb52fdc report: select: refactor: move str_list to libdm
The list of strings is used quite frequently and we'd like to reuse
this simple structure for report selection support too. Make it part
of libdevmapper for general reuse throughout the code.

This also simplifies the LVM code a bit since we don't need to
include and manage lvm-types.h anymore (the string list was the
only structure defined there).

e585a6bbcf signals: better nesting support
Support upto 3 levels os nesting signal blocking.
As of today - code blocks signals immediatelly when it opens
VG in read-write mode - this however makes current prompt usage
then partially unusable since user may not 'break' command
during prompt (something most user would expect).

Until a better fix for prompting is implemented, put in support
for signal nesting - thus when prompt enables signal acceptance,
make it possible to really break command at this point.
