254d672dcc Add pv_uuid_dup, vg_uuid_dup, and lv_uuid_dup, and call id_format_and_copy.
Add supporting functions for pv_uuid, vg_uuid, and lv_uuid.
Call new function id_format_and_copy.  Use 'const' where appropriate.
Add "_dup" suffix to indicate memory is being allocated.
Call {pv|vg|lv}_uuid_dup from lvm2app uuid functions.

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.

a6bc975a24 Improve activation monitoring option processing
. Add "monitoring" option to "activation" section of lvm.conf
. Have clvmd consult the lvm.conf "activation/monitoring" too.
. Introduce toollib.c:get_activation_monitoring_mode().
. Error out when both --monitor and --ignoremonitoring are provided.
. Add --monitor and --ignoremonitoring support to lvcreate.  Update
  lvcreate man page accordingly.
. Clarify that '--monitor' controls the start and stop of monitoring in
  the {vg,lv}change man pages.

a6ca9ac0bc Add lvm_lv_get_tags(), lvm_lv_add_tag(), and lvm_lv_remove_tag().
Add lvm2app functions to manage LV tags.
For lvm_lv_get_tags(), we return a list of tags, similar to other
functions that return lists.  An empty list is returned if there
are no tags.  NULL is returned if there is a problem obtaining
the list of tags.

ed3329eb45 Fix off by 512 sizes for lvm2app.
Internally we store sizes in sectors, but lvm2app exports sizes
in bytes.  We could get fancier and allow units configuration but
this fix should do for now.

Fixes rhbz561422.

5d370b1bdd Make lvm2app lv_t handle definition consistent with lvm_t.
This patch update lv_t handle to be consistent with lvm_t - define as a pointer
to internal struct logical_volume.

afcd9399a9 Add an open_mode to the vg struct for liblvm - enforce read / write semantics.
For now, a simple way to enforce the read/write semantics is to just save the
open mode of the VG.  If the caller uses lvm_vg_create, the mode is write.
The caller using lvm_vg_open can use either read or write to open the VG.
Once we have this, we enforce the permissions on each API call and don't allow
a caller to modify a VG that has not been opened properly.

This may be better combined with the locking mode, but I view that as future
cleanup, past this initial release.  The intial release should enforce the
basic object semantics though, as described in the lvm.h file.

63b186b6f7 Implement lvm_lv_activate and lvm_lv_deactivate liblvm calls.
Limited implementation but other types of activation should probably have
separate calls.  We also currently do not handle pvmoves or lvconverts.

f864285b3a Update liblvm status return codes to be consistent.
For now, we use the following scheme.
For APIs that return an int, success is 0, fail is -1.
APIs that return handles, success is non-NULL, fail is NULL.
At this early stage, liblvm error handling mechanism is subject to change,
but for now we go with this simple scheme consistent with system
programming.

8bcb96836d Add lvm_vg_remove_lv liblvm function.
Add a very simple version of lvm_vg_remove_lv.
Since we currently can only create linear LVs, this simple remove function
is adequate.  We must refactor lvremove_single a bit.

83f25cd121 Add most all liblvm 'get' functions needed for anaconda.
Add the most straightforward 'get' functions required for anaconda.
These are the ones that return simple uint64_t values.
The other more complex ones involve the lv_attr bits.  These will
come in a separate patch series since each lv_attr bit will be returned
in a separate API instred of returning the string and requiring the
user to parse it.

f032ed7498 Add lvm_{pv|vg|lv}_get_{uuid|name}.
Caller must free the memory of the uuid / name returned.
This may not be the best memory management policy since it may lead to
memory leaks if the caller has code like this:
if (!lvm_vg_get_name(vg))

Maybe we don't care - if we do we can use pools tied to handles later
or some other scheme.
