[PATCH 3/3] btrfs-progs: add more parameter to the filesystem show

[Anand Jain <anand.jain@oracle.com>]

for mounted btrfs filesystem this patch proposes to add
information to also show the mount point and group profile,
to help user to quickly understand near details of the
btrfs filesystem

end user using this new btrfs fi show would surely notice this
will reduce other commands normally used following the current
btrfs fi show command. (like mount and btrfs fi df). of course
user should use fi df to know detailed info about the sizes.

preview as below..

Label: none  uuid: 26d539a5-8968-4cf0-b4b5-5fd50105f8a0 mounted: /btrfs
	Group profile: Metadata: single  Metadata: DUP  Data: single
	Total devices 1 FS bytes used 28.00KiB
	devid    1 size 1.98GiB used 238.25MiB path /dev/mapper/mpatha
