7f97c7ea9a build: Don't generate symlinks in include/ dir
As we start refactoring the code to break dependencies (see doc/refactoring.txt),
I want us to use full paths in the includes (eg, #include "base/data-struct/list.h").
This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in
metadata/ from base/

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.

245b85692e config: use config checks and add support for creating trees from config definition (config_def_create_tree fn)
Configuration checking is initiated during config load/processing
(_process_config fn) which is part of the command context
creation/refresh.

This patch also defines 5 types of trees that could be created from
the configuration definition (config_settings.h), the cfg_def_tree_t:

  - CFG_DEF_TREE_CURRENT that denotes a tree of all the configuration
    nodes that are explicitly defined in lvm.conf/--config

  - CFG_DEF_TREE_MISSING that denotes a tree of all missing
    configuration nodes for which default valus are used since they're
    not explicitly used in lvm.conf/--config

  - CFG_DEF_TREE_DEFAULT that denotes a tree of all possible
    configuration nodes with default values assigned, no matter what
    the actual lvm.conf/--config is

  - CFG_DEF_TREE_NEW that denotes a tree of all new configuration nodes
    that appeared in given version

  - CFG_DEF_TREE_COMPLETE that denotes a tree of the whole configuration
    tree that is used in LVM2 (a combination of CFG_DEF_TREE_CURRENT +
    CFG_DEF_TREE_MISSING). This is not implemented yet, it will be added
    later...

The function that creates the definition tree of given type:

  struct dm_config_tree *config_def_create_tree(struct config_def_tree_spec *spec);

Where the "spec" specifies the tree type to be created:

  struct config_def_tree_spec {
    cfg_def_tree_t type;	/* tree type */
    uint16_t version;		/* tree at this LVM2 version */
    int ignoreadvanced;		/* do not include advanced configs */
    int ignoreunsupported;	/* do not include unsupported configs */
  };

This tree can be passed to already existing functions that write
the tree on output (like we already do with cmd->cft).

There is a new lvm.conf section called "config" with two new options:

  - config/checks which enables/disables checking (enabled by default)

  - config/abort_on_errors which enables/disables aborts on any type of
    mismatch found in the config (disabled by default)

70f57996b3 RAID: Add new 'raid10_segtype_default' setting in lvm.conf
If '--mirrors/-m' and '--stripes/-i' are used together when creating
a logical volume, mirrors-over-stripes is currently chosen.  The user
can override this by using the '--type raid10' option on creation.
However, we want a place where we can set the default behavior to
'raid10' explicitly - similar to the "mirror" and "raid1" tunable,
mirror_segtype_default.

A follow-on patch should use this new setting to change the default
from "mirror" to "raid10", as this is the preferred segment type.

0e4ffd9d3b clean-up: Rename lvm.conf setting 'mirror_region_size' to 'raid_region_size'
We have been using 'mirror_region_size' in lvm.conf as the default region
size for RAID logical volumes as well as mirror logical volumes.  Since,
"raid" is more inclusive and representative than "mirror", I have changed
the name of this setting.  We must still check for the old setting and warn
the user if we are overriding it with the new setting if both happen to be
present.

7f747a0d73 logging: add debug classes
Add log/debug_classes to lvm.conf to allow debug messages to be
classified and filtered at runtime.

The dm_errno field is only used by log_error(), so I've redefined it
for log_debug() messages to hold the message class.

By default, all existing messages appear, but we can add categories that
generate high volumes of data, such as logging all traffic to/from
lvmetad.

3acc85caa8 buffering: use unbuffered silent mode for liblvm

438e0050df config: add silent mode
Accept -q as the short form of --quiet.
Suppress non-essential standard output if -q is given twice.
Treat log/silent in lvm.conf as equivalent to -qq.
Review all log_print messages and change some to
log_print_unless_silent.

When silent, the following commands still produce output:
dumpconfig, lvdisplay, lvmdiskscan, lvs, pvck, pvdisplay,
pvs, version, vgcfgrestore -l, vgdisplay, vgs.
[Needs checking.]

Non-essential messages are shifted from log level 4 to log level 5
for syslog and lvm2_log_fn purposes.
