9775a19af1 lib/properties: Common code for handling properties.
The common bits from lib/report/properties.[c|h] have
been moved to lib/properties/prop_common.[c|h] to allow
re-use of property handling functionality without
polluting the report handling functionality.

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.

c6f48b7c1a refactor: make device type recognition code common for general use
Changes:

- move device type registration out of "type filter" (filter.c)
to a separate and new dev-type.[ch] for common use throughout the code

- the structure for keeping the major numbers detected for available
device types and available partitioning available is stored in
"dev_types" structure now

- move common partitioning detection code to dev-type.[ch] as well
together with other device-related functions bound to dev_types
(see dev-type.h for the interface)

The dev-type interface contains all common functions used to detect
subsystems/device types, signature/superblock recognition code,
type-specific device properties and other common device properties
(bound to dev_types), including partitioning support.

- add dev_types instance to cmd context as cmd->dev_types for common use

- use cmd->dev_types throughout as a central point for providing
information about device types

e947c362dd config: add config_settings.h
This file centrally defines all recognized LVM2 configuration
sections and settings. Each item here has its parent, set of
allowed types, default value, brief comment, version the setting
first appeared in and flags that further define the nature of
the configuration setting and its use.

07113beea3 Do not scan device if it is part of active multipath.
Add filter which tries to check if scanned device is part
of active multipath.

Firstly, only SCSI major number devices are handled in filter.

Then it checks if device has exactly one holder (in sysfs) and
if it is device-mapper device and DM-UUID is prefixed by "MPATH-".

If so, this device is filtered out.

The whole filter can be switched off by setting
mpath_component_detection in lvm.conf.

8191fe4f4a Refactor the percent (mirror sync, snapshot usage) handling code to use
fixed-point values instead of a combination of a float value and an enum.

b171907fc5 Refactor metadata.[ch] into lv.[ch] for lv functions.
This patch is similar to the other patches for pv and vg
functionality, and separates lv functionality into separate
files, concentrating on reporting fields and simple functions.

f42b708eae Refactor metadata.[ch] into pv.[ch] for pv functions.
The metadata.[ch] files are very large.  This patch makes a first
attempt at separating out pv functions and data, particularly
related to the reporting fields calculations.

More code could be moved here but for now I'm stopping at reporting
functions 'get' / 'set' functions.

fc65b9038e Add properties.[ch] to lib/report, defined based on columns.h.
Extend the existing reporting infrastructure definitions and structures
to include a 'get' and 'set' function for each field.  We will provide
a 'get' and 'set' function for each of these fields, which will be utilized
by exported lvm2app functions.

Define a default _not_implemented 'get' and 'set' function that just sets
an errno and returns 0.  Future patches will actually implement the
specific 'get' and 'set' functions for each property.  For read-only
properties, only the 'get' function will be implemented.

Define vg_get_property() function to query a property.  We will call
this from a lvm2app function.
