David Teigland 40ed782077 lvresize: add new options and defaults for fs handling
The new option "--fs String" for lvresize/lvreduce/lvextend
controls the handling of file systems before/after resizing
the LV.  --resizefs is the same as --fs resize.

Possible --fs values:

checksize
  Only used when reducing the size, does nothing when exending.
  Check the fs size, and reduce the LV if the fs is not using
  the affected space, i.e. the fs does not need to be shrunk.
  Fail the command without reducing the fs or LV if the fs is
  using the affected space.

resize_remount | resize
  Resize the fs if needed. Mounts or unmounts the fs as
  required (avoids mounting/unmounting when possible.)
  Attempts to restore the original mount state when finished.

resize_keepmount
  Resize the fs if needed, only if it can be done without
  changing the current mount state. Fail the command without
  resizing the fs or LV if an fs resize requires mounting or
  unmounting.

resize_unmount
  Resize the fs if needed, only while unmounted. Unmount the
  fs if needed.  Fail the command without resizing the fs
  or LV if an fs resize is needed that requires the the fs
  to be mounted.

resize_fsadm
  Use the old method of calling fsadm to do handle the fs
  (deprecated).

ignore
  Resize the LV without checking for or handling a file system.

Notes on lvreduce:

When no --fs or --resizefs option is specified:
. lvextend default behavior is fs ignore.
. lvreduce default behavior is fs checksize
  (includes activating the LV.)

With the exception of --fs resize_fsadm|ignore, lvreduce requires
the recent libblkid fields FSLASTBLOCK and FSBLOCKSIZE.
FSLASTBLOCK*FSBLOCKSIZE is the last byte used by the fs on the LV,
which determines if reducing the fs is necessary.
