c5e6bc393e metadata: read VG/LV profile name from metadata if it exists and load it
This is per VG/LV profile loading on demand. The profile itself is saved
in struct volume_group/logical_volume as "profile" field so we can
reference it whenever needed.

bfde83eb34 config: add override_config_tree_from_profile fn to add the profile to a configuration cascade
When placing the profile in a configuration cascade, this sequence is
used exactly:

CONFIG_STRING -> CONFIG_PROFILE -> CONFIG_FILE/MERGED_FILES

So if the profile is used, it overloads the lvm.conf (and any
existing tag configs). However, if "--config" is used to define
a custom configuration on command line, this overloads even the
profile config!

ebc236d085 config: add support for loading profiles
This patch adds --profile arg to lvm cmds and adds config/profile_dir
configuration setting to select the directory where profiles are stored
By default it's /etc/lvm/profile.

The profiles are added by using new "add_profile" fn and then loaded
using the "load_profile" fn. All profiles are stored in a cmd context
within the new "struct profile_params":

struct profile_params {
  const char *dir;
  struct profile *global_profile;
  struct dm_list profiles_to_load;
  struct dm_list profiles;
};

...where "dir" is the directory with profiles, "global_profile" is
the profile that is set globally via the --profile arg (IOW, not
set per VG/LV basis based on metadata record) and the "profiles"
is the list with loaded profiles.

f89a8b81cf configure: add configure --with-default-profile-subdir
Configuration profiles are selected configuration items that can
be loaded dynamically on demand and overlayed over existing
configuration on demand (either on cmd line by selecting the profile
name to be used globally or retrieved from metadata and used per
VG/LV basis only).

The default directory where profiles are stored is configurable
at compile time with --with-default-profile-subdir.

da3ea66a96 config: add config_source_t type to identify configuration source
A helper type that helps with identification of the configuration source
which makes handling the configuration cascade a bit easier, mainly
removing and adding configuration trees to cascade dynamically.

Currently, the possible types are:

  CONFIG_UNDEFINED - configuration is not defined yet (not initialized)
  CONFIG_FILE - one file configuration
  CONFIG_MERGED_FILES - configuration that is a result of merging more files into one
  CONFIG_STRING - configuration string typed on cmd line directly
  CONFIG_PROFILE - profile configuration (the new type of configuration, patches will follow...)

Also, generalize existing "remove_overridden_config_tree" to work with
configuration type identification in a cascade. Before, it was just
the CONFIG_STRING we used. Now, we need some more to add in a
cascade (like the CONFIG_PROFILE). So, we have:

  struct dm_config_tree *remove_config_tree_by_source(struct cmd_context *cmd, config_source_t source);
  config_source_t config_get_source_type(struct dm_config_tree *cft);

... for removing the tree by its source type from the cascade and
simply getting the source type.

b31725d0ae archive: add missing bit set
In the last update not all code paths have set the archived flag.
If we run in test mode or without archiving enabled - set the bit
as well - so test whether archiving has been called succesfully
will be ok. (in relase fix).

0ca1688134 metadata: log_debug only when BA found in metadata

a6d13308ec RAID/MIRROR: Honor mirror_segtype_default when upconverting linear LVs
If the user would upconvert a linear LV to a mirror without specifying
the segment type ("--type mirror" vs "--type raid1"), the "mirror"
segment type would be chosen without consulting the 'default_mirror_segtype'
setting in lvm.conf.  This is now used as the basis for determining
which should be used if left unspecified.

2562968864 vgcfgrestore: fix crash on restore of wrong vgname
When vgname has not existed in metadata, it has crashed on double free
in format_instance destroy() -  since VG was created, used FID and was
released - which also released FID, so further use was accessing bad
memory.

Fix it for this code path before release_vg() so FID will exists
when _vg_read_file_name() returns NULL.
