26889b3bb6 snapshot: check merging_cow is cow
Check first the LV is cow before even checking it's a merging COW.
Note: previosly merging_cow was also merging origin, so without
this explicit check it used to return '1' also when passed
LV has been merging origin.

e9ee2cb6b6 report: fix report copy_percent value
When mirror/raid called copy_percent function to return,
when 100% was supposed to be returned, wrong float 100.0 value
could have been reported back instead of dm_percent_t DM_PERCENT_100.

There is broken API somewhere, since the function here rely on
actively being modifid VG content even when doing 'lvs' operation.

780424639a Revert "libdm: trace missing settings"
This reverts commit 8fd886f735.

This was a deliberate omission because logging token-by-token metadata
parsing greatly increases the amount of logging for hardly any benefit.

In general, only LVM config file settings need to be logged, and in
places where it's considered important to log particular elements of
metadata that should be done using specific log_* lines.

This area can be revisited.

2f2b3c9100 lvconvert: use process_each_lv
In the same way that process_each_vg() can be passed
a single VG name to process, also allow process_each_lv()
to be passed a single VG name and LV name to process.

9b640c3684 pvscan: use process_each_vg for autoactivate
This refactors the code for autoactivation.  Previously,
as each PV was found, it would be sent to lvmetad, and
the VG would be autoactivated using a non-standard VG
processing function (the "activation_handler") called via
a function pointer from within the lvmetad notification path.

Now, any scanning that the command needs to do (scanning
only the named device args, or scanning all devices when
there are no args), is done first, before any activation
is attempted.  During the scans, the VG names are saved.
After scanning is complete, process_each_vg is used to do
autoactivation of the saved VG names.  This makes pvscan
activation much more similar to activation done with
vgchange or lvchange.

The separate autoactivate phase also means that if lvmetad
is disabled (either before or during the scan), the command
can continue with the activation step by simply not using
lvmetad and reverting to disk scanning to do the
activation.

591ef307b3 lvm2_activation_generator: don't create full context for liblvm2app
Don't use lvm_init() to create a full command context, which
does a lot of command setup (like connecting to daemons), which
is unnecessary for simply reading a value from lvm.conf.

Passing a NULL context arg to the lvm_config_ function is now
allowed, in which case lvm.conf is read without doing lvm
command setup.

7fd4119d24 liblvm: allow config settings to be read without full lvm cmd
A program may be using liblvm2app for simply checking a config
setting in lvm.conf.  In this case, a full lvm context is not
needed, only cmd->cft (which are the config settings read from
lvm.conf).

lvm_config_find_bool() can now be passed a NULL lvm context
in which case it will only create cmd->cft, check the config
setting asked for, and destroy the cmd.

7ef152c072 python: move lvm_init
Only call lvm_init() when it's needed so that simply
loading the lvm python code in another program doesn't
make that program do lvm initialization.

The version call doesn't need a handle.

The garbage collection can just do lvm_quit to destroy
the command.  The next call that needs lvm_init will
do it first.

87d9406725 lib: fix init error handling
When setting up a toolcontext, the lib init function
was detecting an error when there was none, and then
it was returning an incompletely initialized cmd struct
instead of NULL.  The effect was that the lib would try
to use the uninitialized cmd struct and segfault.
This would happen if a non-fatal error occurred during
cmd setup, e.g. user permission failed on lvmetad socket,
causing cmd to fall back to scanning and not use lvmetad.

The only real error condition is when create_toolcontext
returns NULL.  If cmd is returned, the lib can use it.

5c18b0ce9c refactor: separate original _report fn into _report and _do_report fn
The _report fn is getting big - separate it in two:

  - _report fn to get all the options and arguments
  - _do_report fn for reporting itself

Also, place all the variables/arguments in one structure for easier
handling of the variables around.
