8cfc385491 toollib: make it possible to also process internal VGs, add 'include_internal' switch to process_each_vg fn
The lvm fullreport works per VG and as such, the vg, lv, pv, seg and
pvseg subreport is done for each VG. However, if the PV is not part of
any VG yet, we still want to display pv and pvseg subreports for these
"orphan" PVs - so enable this for lvm fullreport's process_each_vg call.

f752a95302 toollib: add 'parent' field to processing_handle; init report format only if there's no parent
If there's parent processing handle, we don't need to create completely
new report group and status report - we'll just reuse the one already
initialized for the parent.

Currently, the situation where this matter is when doing internal report
to do the selection for processing commands where we have parent processing
handle for the command itself and processing handle for the selection
part (that is selection for non-reporting tools).

bf8d00985a raid0: Add raid0 segment type.
This remains experimental and quite restrictive so should only be used
for testing at this stage.  (E.g. lvreduce is not supported.)

097a724bda lvcreate: %FREE -> %PVS
This is hotfix for RHBZ: https://bugzilla.redhat.com/1324537
However already the %FREE is not a good fit and we need something
better. Meanwhile make  -l%PVS work at least as good as %FREE
for thin-pool.

TODO: this needs rework - it should be allocator to do all the size
decisions at one place.

a631fa20d0 cache: disallow stripes/size for cache pool
ATM allocation can't handle stripping and cache pool allocation.
It's not yet even clear what should be actually result.
Until resolved, disable this option (it's been coredumping
inside allocation anyway).

3ec4813ba2 coverity: fix missing initialization
... Using uninitialized value "lockd_state" when calling "lockd_vg"
(even though lockd_vg assigns 0 to the lockd_state, but it looks at
previous state of lockd_state just before that so we need to have
that properly initialized!)

libdm/libdm-report.c:2934: uninit_use_in_call: Using uninitialized value "tm". Field "tm.tm_gmtoff" is uninitialized when calling "_get_final_time".

daemons/lvmlockd/lvmlockctl.c:273: uninit_use_in_call: Using uninitialized element of array "r_name" when calling "format_info_r_action". (just added FIXME as this looks unfinished?)

035276ab83 lvcreate: do not silently accept '-m #' with raid4/5/6
If the user provides '-m #' (# > 0) with mappings
raid4/5/6, the command silently creates
'#mirrors * #stripes + #parity' image component pairs.

Patch rejects '-m #' altogether for those mappings
in order to avoid LV creation with unexpected layout.

e0164f2188 sparse: configurable type for sparse volumes
Support compile type configurable defaults for creation
of sparse volumes.

By default now create 'thin-pools' for sparse volumes.
Use the global/sparse_segtype_default to switch back to old
snapshots if needed.

Apply the same compile logic for newly introduces mirror/raid1 options.

c9fbbf48ba cache: support more args
Unlike with thin-pool - with cache we support all args also
directly when create cache volume.

So the result of 'separate' cache-pool creation and setting its
options should give same result as specifying those args
during cache creation.

Cache-pool values are used as defaults if the params are
not specified with cache creation.

784c216d2b lvcreate: check for conflicting -Zy -Wy
Let the finaly state of zero & wipe_signature to be
resolved later together with all the types.

Don't play with zero assigment and segtype flag
(i.e. thin-pool -Z  has different meaning).

Check if the passed options do allow requested zeroing/wiping.

lvcreate without -Z or -W will fallback to warning if the device
cannot be zeroed, however if user requested them explicitely
it will give user error.

d13239b054 lvcreate: new validation code
Refactor lvcreate code.

Prefer to use arg_outside_list_is_set() so we get automatic 'white-list'
validation of supported options with different segment types.

Drop used lp->cache, lp->cache and use seg_is_cache(), seg_is_thin()

Draw clear border where is the last moment we could change create
segment type.

When segment type is given with --type - do not allow it to be changed
later.

Put together tests related to individual segment types.

Finish cache conversion at proper part of lv_manip code after
the vg_metadata are written - so we could correcly clean-up created
stripe LV for cache volume.

0cbb381e15 lvcreate: regression fix on lv name limits
When we are given an existing LV name - it needs to be allowed
to pass in even restricted name as the LV could have existed
long before we introduced some new restriction on prefix/suffix.i

Fix the regression on name limits and drop restriction to be applied
on any existing LVs - only the new created LV names have to be
complient with current name restrictions.

FIXME: we are currently using restricted names incorrectly in few
other places - device_is_usable() skips restricted names,
and udev flags are also incorrectly set for restricted names
so these LVs are not getting links properly.
