Dave Wysochanski 629efc6a89 Export lvm_pv_get_size(), lvm_pv_get_free(), lvm_pv_get_dev_size in lvm2app. 
We add these exports to show the pv_size and pv_free and dev_size
fields.
Fixes rhbz561423.

/*
* This file defines the fields (columns) for the reporting commands
* (pvs/vgs/lvs).
*/
/*
* The 'FIELD' macro arguments are defined as follows:
* 1. report_type. An enum value that selects a specific
* struct dm_report_object_type in the _report_types array. The value is
* used to select the containing base object address (see *obj_get*
* functions) for any data values of any field in the report.
* 2. Containing struct. The structure that either contains the field data
* as a member or should be used to obtain the field data. The containing
* struct should match the base object of the report_type.
* 3. Field type. This must be either 'STR' or 'NUM'.
* 4. Report heading. This is the field heading that is displayed by the
* reporting commands.
* 5. Data value pointer. This argument is always a member of the
* containing struct. It may point directly to the data value (for example,
* lv_uuid - see _uuid_disp()) or may be used to derive the data value (for
* example, seg_count - see _lvsegcount_disp()). In the FIELD macro
* definition, it is used in an offset calculation to derive the offset to
* the data value from the containing struct base address. Note that in some
* cases, the argument is the first member of the struct, in which case the
* data value pointer points to the start of the struct itself (for example,
* 'lvid' field of struct 'lv').
* 6. Minimum display width. This is the minimum width used to display
* the field value, typically matching the width of the column heading.
* 7. Display function identifier. Used to derive the full name of the
* function that displays this field. Derivation is done by appending '_'
* then prepending this argument to '_disp'. For example, if this argument
* is 'uuid', the display function is _uuid_disp(). Adding a new field may
* require defining a new display function (for example _myfieldname_disp()),
* or re-use of an existing one (for example, _uint32_disp()).
* 8. Unique format identifier / field id. This name must be unique and is
* used to select fields via '-o' in the reporting commands (pvs/vgs/lvs).
* The string used to specify the field - the 'id' member of
* struct dm_report_field_type.
* 9. Description of field. This is a brief (ideally <= 52 chars) description
* of the field used in the reporting commands.
