39d6ccdfc7 Define handles to liblvm objects for pv, vg, lv, lvseg, pvseg.
Define the 5 main liblvm objects to be the pv, vg, lv, lvseg, and pvseg.
We need handles defined to all these objects in order for liblvm to be
equivalent to the reporting commands pvs, vgs, and lvs.

- move vg_t, lv_t, and pv_t from metadata-exported.h into lvm.h
- move lv_segment and pv_segment forward declarations into lvm.h
- add lvseg_t and pvseg_t to lvm.h

NOTE: We currently have an inconsistency in handle definitions.
lvm_t is defined as a pointer, while these other handles are just
structures.  We should pick one scheme and be consistent - perhaps
define all handles as pointers (this is what I've seen elsewhere).

6452d4ae9d Refactor vgsplit - move move_pvs_used_by_lv and move_pv inside library.
In the future we may export these functions or something like them in liblvm
For now this helps in cleaning up the checks for RESIZEABLE since we can
use the internal library function vg_bad_status_bits.

42ae96fa3d Remove force parameter from vg_remove_single, now the liblvm function.
Move check for active LVs outside of library function.  The vgremove
liblvm function function will fail if there are active LVs.  It will
be the application's responsibility to check this condition and remove
the LVs individually before calling vgremove.  Note also that we've
duplicated the EXPORTED_VG check in vgremove_single (tools) and
vg_remove_single (library).  Duplication seemed the only option here
since we don't want to do the automatic removal of LVs (in the tools)
if the vg is exported, and we still need to protect the library call
from removal if the vg is exported.

We still need to deal with the ORPHAN lock but vg_remove_single is now
very close to our liblvm function.

TODO: Refactor lvremove in a similar way.

10a27bdfb6 Change vg_create() to take only minimal parameters and obtain a lock.
vg_t *vg_create(struct cmd_context *cmd, const char *vg_name);
This is the first step towards the API called to create a VG.
Call vg_lock_newname() inside this function.  Use _vg_make_handle()
where possible.
Now we have 2 ways to construct a volume group:
1) vg_read: Used when constructing an existing VG from disks
2) vg_create: Used when constructing a new VG
Both of these interfaces obtain a lock, and return a vg_t *.
The usage of _vg_make_handle() inside vg_create() doesn't fit
perfectly but it's ok for now.  Needs some cleanup though and I've
noted "FIXME" in the code.

Add the new vg_create() plus vg 'set' functions for non-default
VG parameters in the following tools:
- vgcreate: Fairly straightforward refactoring.  We just moved
vg_lock_newname inside vg_create so we check the return via
vg_read_error.
- vgsplit: The refactoring here is a bit more tricky.  Originally
we called vg_lock_newname and depending on the error code, we either
read the existing vg or created the new one.  Now vg_create()
calls vg_lock_newname, so we first try to create the VG.  If this
fails with FAILED_EXIST, we can then do the vg_read.  If the
create succeeds, we check the input parameters and set any new
values on the VG.

TODO in future patches:
1. The VG_ORPHAN lock needs some thought.  We may want to treat
this as any other VG, and require the application to obtain a handle
and pass it to other API calls (for example, vg_extend).  Or,
we may find that hiding the VG_ORPHAN lock inside other APIs is
the way to go.  I thought of placing the VG_ORPHAN lock inside
vg_create() and tying it to the vg handle, but was not certain
this was the right approach.
2. Cleanup error paths. Integrate vg_read_error() with vg_create and
vg_read* error codes and/or the new error APIs.

3f6a21ead4 Rename vg_change_pesize to vg_set_extent_size and use vg_t.
In liblvm, we will reserve the word 'change' to mean an API that
both sets one or more values, and commits to disk.  This will be
consistent with the LVM commandline.  The existing vg_change_pesize()
function does not commit to disk, but just changes the extent_size
and ensures all internal structures are updated.  This logic should
be contained in a function that sets the value.

4c35d6dee6 Remove unneeded LOCK_NONBLOCKING from vg_read() API.
Remove unneeded LOCK_NONBLOCKING from vg_read() API and tools that

    Remove NON_BLOCKING lock flag from tools and set a policy to auto-set.

    As a simplification to the tools and further liblvm, this patch pushes
    the setting of NON_BLOCKING lock flag inside the lock_vol() call.
    The policy we set is if any existing VGs are currently locked, we
    set the NON_BLOCKING flag.

At some point it may make sense to add this flag back if we get an
RFE from a liblvm user, but for now let's keep it as simple as
possible.

07b0c948ee Add vg_lock_newname() library function.
Various tools need to check for existence of a VG before doing something
(vgsplit, vgrename, vgcreate).  Currently we don't have an interface to
check for existence, but the existence check is part of the vg_read* call(s).
This patch is an attempt to pull out some of that functionality into a
separate function, and hopefully simplify our vg_read interface, and
move those patches along.

vg_lock_newname() is only concerned about checking whether a vg exists in
the system.  Unfortunately, we cannot just scan the system, but we must first
obtain a lock.  Since we are reserving a vgname, we take a WRITE lock on
the vgname.  Once obtained, we scan the system to ensure the name does
not exist.  The return codes and behavior is in the function header.
You might think of this function as similar to an open() call with
O_CREAT and O_EXCL flags (returns failure with -EEXIST if file already
exists).

NOTE: I think including the word "lock" in the function name is important,
as it clearly states the function obtains a lock and makes the code more
readable, especially when it comes to cleanup / unlocking.  The ultimate
function name is somewhat open for debate though so later we may rename.

66086ce962 Fix double releasing of vg when repairing of vg is requested.
Several commands calls process_each_vg() and in provided
callback it explicitly recovers VG if inconsistent.
(vgchange, vgconvert, vgscan)

It means that old VG is released and reread  but the function
above (process_one_vg) tries to unlock and release old VG.

Patch moves the repair logic into _process_one_vg() function.

It always tries to read vg (even inconsistent) and then decides
what to do according new defined parameter.

Also patch unifies inconsistent error messages.

The only slight change if for vgremove command, where
it now tries to repair VG before it removes if force arg is given.
(It works similar way before, just the order of operation changed).

31f55a07db Fix convert polling to ignore LV with different UUID.
When mirror convert polling is started (mainly as backgound process,
in lvchange -a y or in lvconvert itself) it tries to read VG
and LV identified by its name.

Unfortunatelly, the VG can have already different LV under the same name,
and various more or less funny things can happen (note that
_finish_lvconvert_mirror suspends the volume for example).

(the typical example is our testing script which continuously recreates
LVs under the same name in the same VG.)

This patch adds optional uuid parameter which helps to properly
select the monitoring object. For lvconvert polling it is set to LV UUID
and both _get_lvconvert_vg and _get_lvconvert_lv uses it to read proper VG/LV.

(In the pvmove case it is NULL, here we poll for physical volume name).

8e1d5615b4 Introduce memory pool per volume group.
Since now, all code reading volume group is responsible for releasing
the memory allocated by calling vg_release(vg).
(For simplicity of use, vg_releae can be called for vg == NULL,
the same logic like free(NULL)).

Also providing simple macro for unlocking & releasing in one step,
tools usualy uses this approach.

The global memory pool (cmd->mem) should be used only for global
physical volume operations.

This patch have to be applied with all subsequent patches to complete
memory pool per vg logic.

Using separate memory pool has quite bit memory saving impact when
using large VGs, this is mainly needed when we have to use
preallocated and locked memory (and should not overflow from that
memory space).

8929ce6651 Add --dataalignment to pvcreate to specify alignment of data area. (mbroz)
This patch is not fully tested and leaves some related bugs unfixed.

Intended behaviour of the code now:

  pe_start in the lvm2 format PV label header is set only by pvcreate (or
vgconvert -M2) and then preserved in *all* operations thereafter.

  In some specialist cases, after the PV is added to a VG, the pe_start
field in the VG metadata may hold a different value and if so, it
overrides the other one for as long as the PV is in such a VG.

  Currently, the field storing the size of the data area in the PV label
header always holds 0.  As it only has meaning in the context of a
volume group, it is calculated whenever the PV is added to a VG (and can
be derived from extent_size and pe_count in the VG metadata).
