d81498a824 Initialize dmeventd monitoring for every command
Read lvm.conf setting for monitoring for each command. So we should not
activate monitoring if the default compilation is set to monitor during
lvconvert commnads.

Patch also removes check for  clustered VG and allows to disable monitoring
for clustered VG with the assumption, the problem with monitoring and dmeventd
flag passing for INGNORE is already fixed.

077a6755ff Replace free_vg with release_vg
Move the free_vg() to  vg.c  and replace free_vg  with release_vg
and make the _free_vg internal.

Patch is needed for sharing VG in vginfo cache so the release_vg function name
is a better fit here.

53dd32f41d Add proper udev library context initialization and finalization to liblvm.
This was missing in liblvm and it caused all udev-related operations to
not take effect when using liblvm, e.g. obtaining the list of devices from udev
db instead of scanning the whole /dev which also recreated the .cache as a side
effect. This was also the case with udisks-lvm-pv-export prober which is run
from within udev rules whenever the CHANGE event is fired.

eee66d2a80 When glibc needs buffers for line buffering of input and output buffers, it
allocates these buffers in such way it adds memory page for each such buffer
and size of unlock memory check will mismatch by 1 or 2 pages.

This happens when we print or read lines without '\n' so these buffers are
used. To avoid this extra allocation, use setvbuf to set these bufffers ahead.

aec2115410 Const fixing
Fixing some const warnings - with API change in:

int vg_extend(struct volume_group *vg, int pv_count, const char *const *pv_names,

Change is needed - as lvm2api expects const behaviour here.
So vg_extend() is doing local strdup for unescaping.

skip_dev_dir return const char* from const char* vg_name.

Rest of the patch is cleanup of related warnings.

Also using dm_report_filed_string() API change to simplify
casting in _string_disp and _lvname_disp.

3c1febe0a8 Add lvm_vg_get_property() generic vg property function.
Add a generic VG property function to lvm2app.  Call the internal library
vg_get_property() function.  Strings are dup'd internally.
Rework lvm_vg_get_property to return lvm_property_value and require caller
to check 'is_valid' flag.  If !is_valid, the caller can check lvm_errno()
for the specific error.

Create a 'get_property' function, local to lvm2app, that factors out
most of the common code that copies the components of lvm_property_type
into lvm_property_value.  This allows for a 1-line function for each
of the generic property functions exported by lvm2app.

0d23926e4e Add lvm2app interfaces to lookup a vgname from a pvid and pvname.
lvm2app forces applications to start with a volume group name,
open the volume group, then operate on individual pvs.  In some
cases the application may want to start with a device name rather
than the volume group name.  Today, if an application wants to
do this, it must iterate through all the volume groups to find
the volume group that the specific device is attached to.
These new interfaces allow the application to avoid such overhead.
Bump the lvm2app version number to 3.

75e69cd1b2 Switch to use Requires.private for devmapper.pc and lvm2app.pc
Use Requires.private: instead of Libs.private:
Use UDEV_PC and SELINUX_PC for Require.private:

It looks like usage of Requires.private is prefered from Libs.private.
However pkg-config documentation is really poor here. But here is
short outcome:

There is a difference in Libs.private: and Requires.private: where
we specify libselinux instead of  -lselinux -lsepol.

We leave resolving of query like 'pkg-config --libs --static devmapper'
on taking proper selinux and udev libs to their .pc files instead of
hardcoding them into our .pc file which is might give incorrect answer.
- i.e. dependency of libselinux package might change and we may return
wrong list of linked libraries.
