ef3ab801e8 lvm2app: Add function to retrieve list of PVs V3
As locks are held, you need to call the included function
to release the memory and locks when done transversing the
list of physical volumes.

V2: Rebase fix
V3: Prevent VGs from getting cached and then write protected.

49d7596581 lvm2app: Implement lv resize (v3)

v3: Rebase changes to make work.  Needed to set sizeargs = 1
to indicate to resize that we are asking for a size based
resize.

4d5de8322b lvm2app: Add thin and thin pool lv creation V5
Add thin and thin pool lv creation support to lvm library

This is Mohan's thinp patch, re-worked to include suggestions
from Zdenek and Mohan.

V2: Remove const lvm_lv_params_create_thin
    Add const lvm_lv_params_skip_zero_get

V3: Changed get/set to use generic functions like current
    property

V4: Corrected macro in properties.c

V5: Fixed a bug in liblvm/lvm_lv.c function lvm_lv_create.
    incorrectly used pool instead of lv_name when doing the
    find_lv_in_vg call.

Based on work done by M. Mohan Kumar <mohan@in.ibm.com>

f65dd341a5 locking: Make it possible to pass down an LV to activation code.
Previously, we have relied on UUIDs alone, and on lvmcache to make getting a
"new copy" of VG metadata fast. If the code which triggers the activation has
the correct VG metadata at hand (the version which is currently on disk), it can
now hand it to the activation code directly.

386886f71c config: refer to config nodes using assigned IDs
For example, the old call and reference:

  find_config_tree_str(cmd, "devices/dir", DEFAULT_DEV_DIR)

...now becomes:

  find_config_tree_str(cmd, devices_dir_CFG)

So we're referring to the named configuration ID instead
of passing the configuration path and the default value
is taken from central config definition in config_settings.h
automatically.

86e528c667 lvm2app: No special behavior for 0 for max_snap_size in lvm_lv_snapshot()
It isn't possible to choose a sane default for snapshot size, so just
play it straight and use the passed size instead of adding special
behavior for 0.

Also revert change to Python lib, size parameter must be supplied.

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.

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.
