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.

dd68ee88ea Add lvm_lv_get_property() generic function to obtain value of any lv propert

Add a generic PV property function to lvm2app, similar to VG function.
Return lvm_property_value and require caller to check 'is_valid' flag
before using the value.  If 'is_valid' is not set, then lvm_errno()
should be used to obtain the specific error.

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.

298ec21e29 Use vg->vgmem to allocate vg/lv/pv string properties instead of dm_malloc/fr
Everywhere else in the API the caller can rely on lvm2app taking care of
memory allocation and free, so make the 'name' and 'uuid' properties of a
vg/lv/pv use the vg handle to allocate memory.

Fix add/remove tag function headers.
Fix a lot of little problems with doxygen comments.
Clarify the basic objects and their handles, and place functions with their
appropriate handles/objects.
All this cleanup moves automatic documentation of lvm2app much closer to being
useful as official documentation.  In the future I will add some examples
and plan to build the examples as part of the unit tests.

a5609e3086 Update lvm_vg_write() to handle the deferred commit of lvm_vg_write().
Now that we've refactored the internal library functions that do the
vg_remove, we can handle the deferred commit of a lvm_vg_remove() inside
lvm_vg_write().  This makes the VG create/remove API more consistent in
terms of disk commits - they now both require an lvm_vg_write() to commit
the create or remove to disk.
