Add online resize support (#694622)

Many file systems are capable of growing while mounted, and a few can
even shrink.  This support must be explicitly enabled at configure time
with the --enable-online-resize flag and depends on a patched libparted.
Also requires kernel >= 3.6 for partition resizing, even if the
partition is in use (BLKPG_RESIZE_PARTITION).

Thanks to Mike Fleetwood for double check mark idea instead of a second
column to show the online grow/shrink.

dmraid support use the --enable-libparted-dmraid flag:
E.g., ./configure --enable-libparted-dmraid
Please note that more than one configure flags can be used:
If you wish to build this package with online resize support then
the following is required:
a) A version of libparted that includes the online resize patch.
At time of writing (November 2013), this patch was only
included in Debian and derived distros with parted package
version 2.3-14 or higher.
b) Linux kernel version 3.6 or higher.
Enable with the --enable-online-resize flag:
E.g., ./configure --enable-online-resize
Please note that more than one configure flag can be used:
E.g., ./configure --disable-doc --enable-libparted-dmraid
The INSTALL file contains further GNU installation instructions.
