661406a417 config: fix use of last config check status if creating CFG_DEF_TREE_MISSING tree
When CFG_DEF_TREE_MISSING is created, it needs to know the status
of the check done on the tree used (the CFG_USED flag).

This bug was introduced with f1c292cc38
"make it possible to run several instances of configuration check at
once". This patch separated the CFG_USED and CFG_VALID flags in
a separate 'status' field in struct cft_check_handle.

However, when creating some trees, like CFG_DEF_TREE_MISSING,
we need this status to do a comparison with full config definition
to determine which items are missing and for which default values
were used. Otherwise, all items would be considered missing.

So, pass this status in a new field called 'check_status' in
struct config_def_tree_spec that defines how the (dumpconfig) tree
should be constructed (and this struct is passed to
config_def_create_tree fn then).

7c6526aae2 lvresize: separate validation from action
Start separating the validation from the action in the basic lvresize
code moved to the library.
Remove incorrect use of command line error codes from lvresize library
functions.  Move errors.h to tools directory to reinforce this,
exporting public versions of the error codes in lvm2cmd.h for dmeventd
plugins to use.

6f335ffa35 sigint: improve logic on for sigint reaction
Fix and improve handling on sigint.

Always check for signal presence *before* calling of command,
so it will not call the command when break was hit.

If the command has been finished succesfully there is
no problem to mark the command ok and not report interrupt at all.

Fix cuple related stack; reports and assignments.

50db109e20 liblvm: Moved additional pv resize code
The pv resize code required that a lvm_vg_write be done
to commit the change.  When the method to add the ability
to list all PVs, including ones that are not assocated with
a VG we had no way for the user to make the change persistent.
Thus additional resize code was move and now liblvm calls into
a resize function that does indeed write the changes out, thus
not requiring the user to explicitly write out he changes.

Add thin and thin pool lv creation support to lvm library

This is Mohan's thinp patch, re-worked to include suggestions
from Zdenek and Mohan.

V2: Remove const lvm_lv_params_create_thin
    Add const lvm_lv_params_skip_zero_get

V3: Changed get/set to use generic functions like current
    property

V4: Corrected macro in properties.c

V5: Fixed a bug in liblvm/lvm_lv.c function lvm_lv_create.
    incorrectly used pool instead of lv_name when doing the
    find_lv_in_vg call.

f1c292cc38 config: make it possible to run several instances of configuration check at once
Before, the status of the configuration check (config_def_check fn call)
was saved directly in global configuration definitinion array (as part
of the cfg_def_item_t/flags)

This patch introduces the "struct cft_check_handle" that defines
configuration check parameters as well as separate place to store
the status (status here means CFG_USED and CFG_VALID flags, formerly
saved in cfg_def_item_t/flags). This struct can hold config check
parameters as well as the status for each config tree separately,
thus making it possible to run several instances of config_def_check
without interference.

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.
