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/

ded279f826 report: add support for time (basic)
This patch adds support for time values used in reporting fields.
The raw values are always stored as number of seconds since epoch.

The support that comes with this patch is the basic one which allows
only for recognition of strictly formatted date and time in selection
criteria (the format follows a subset of formats defined by ISO 8601):

  date time timezone

  date:
    YYYY-MM-DD (or shortly YYYYMMDD)
    YYYY-MM (shortly YYYYMM), auto DD=1
    YYYY, auto MM=01 and DD=01

  time:
    hh:mm:ss (or shortly hhmmss)
    hh:mm (or shortly hhmm), auto ss=0
    hh (or shortly hh), auto mm=0, auto ss=0

  timezone (always with + or - sign):
    +hh:mm or -hh:mm (or shortly +hhmm or -hhmm)
    +hh or -hh

Or directly the time (number of seconds) since Epoch (1970-01-01 00:00:00 UTC)
when the number value is prefixed by "@":

   @number_of_seconds_since_epoch

This patch also adds aliases for comparison operators
used together with time values which are more intuitive
to use:
  since (as alias for >=)
  after (as alias for >)
  until (as alias for <=)
  before (as alias for <)

For example:

$ lvmconfig --type full report/time_format
time_format="%Y-%m-%d %T %z %Z [%s]"

$ lvs -o name,time vg
  LV    Time
  lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541]
  lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543]
  lvol2 2015-04-26 14:52:20 +0200 CEST [1430052740]
  lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743]

$ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30"'
  LV    Time
  lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541]
  lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543]
  lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743]

$ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30 6:00"'
  LV    Time
  lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541]
  lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543]

$ lvs vg -o name,time -S 'time since @1435519541'
  LV    Time
  lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541]
  lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543]
  lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743]

This is basic time recognition support that is directly a part of
libdevmapper. Recognition of more free-form expressions will be a
part of subsequent patches.

dc5190de74 lvm2app: Correct missing string properties
Synopsis: STR_LIST needs to be treated as STR for properties.

For any lvm property that was internally 'typed' as a string list we were failing
to return a string in the property API.  This was due to the fact that for the
properties to work the value needs to either be evaulated as a string or a
number.  This change corrects the macro used to build the memory array of
structures so that the string bitfield is set as needed to ensure that the value
is a string.

91f737383c lvm2app: Add signed numerical property values
Currently lvm2app properties have the following structure:

typedef struct lvm_property_value {
        uint32_t is_settable:1;
        uint32_t is_string:1;
        uint32_t is_integer:1;
        uint32_t is_valid:1;
        uint32_t padding:28;
        union {
                const char *string;
                uint64_t integer;
        } value;
} lvm_property_value_t;

which assumes that numerical values were in the range of 0 to 2**64-1.  However,
some of the properties were 'signed', like LV major/minor numbers and some
reserved values for properties that represent percentages.  Thus when the
values were retrieved they were in two's complement notation.  So for a -1
major number the API user would get a value of 18446744073709551615.  The
API user could cast the returned value to an int64_t to handle this, but that
requires the API developer to look at the source code and determine when it
should be done.

This change modifies the return property structure to:

typedef struct lvm_property_value {
        uint32_t is_settable:1;
        uint32_t is_string:1;
        uint32_t is_integer:1;
        uint32_t is_valid:1;
        uint32_t is_signed:1;
        uint32_t padding:27;
        union {
                const char *string;
                uint64_t integer;
                int64_t signed_integer;
        } value;
} lvm_property_value_t;

With this addition the API user can interrogate that the value is numerical,
(is_integer = 1) and subsequently check if it's signed (is_signed = 1) too.
If signed, then the API developer should use the union's signed_integer to
avoid casting.

This change maintains backwards compatibility as the structure size remains
unchanged and integer value remains unchanged.  Only the additional bit
taken from the pad is utilized.

a6694cfc29 report: select: add DM_REPORT_FIELD_TYPE_STRING_LIST to make a difference between STRING and STRING_LIST
The {pv,vg,lv,seg}_tags and lv_modules fields are reported as string
lists using the new dm_report_field_string_list - so we just pass
the list to the fn that takes care of reporting and item sorting itself.
