d5e58768aa tests: check for blkid
When libblkid is not present (older systems) we can't use new -fs tests at
all so skip these tests.

1a67bfe396 tests: extend the usability for older systems
Extend the test a bit futher so we can keep logic of resize
working similarly well for older and newer systems.

Test uses new 'aux have_fsinfo'function to regnize compiled
version of lvm.

aa19f2aa3d tests: update lvextend tests
Make test faster by agregating sets of operation to work on a single
created filesystem yet checking all the variants of extension and reduction.

Split 'xfs' part into separate test and convert it for use of the
minimal size 300M nowdays required by mkfs.xfs.

1857eb9fe0 lvresize: fix check for mounted and renamed LV to handle spaces
Replace spaces with \040 in directory paths from getmntent (mtab).

The recent commit 5374a44c57 compares mount point directory paths
from /etc/mtab and /proc/mounts, in order to detect when a mounted
LV has been renamed.  The directory path comparison does not work
correctly when the path contains spaces because getmntent uses
ascii space chars and proc replaces spaces with \040.

5374a44c57 lvresize: fail early if mounted LV was renamed
If a mounted LV is renamed, then fs resizing utilities will fail,
so detect this condition and fail the command before any changes
are made.

f6f2737015 lvreduce: require active LV when no fs option is used
Without an --fs option set, make lvreduce of an inactive LV
fail and report that the LV must be active.

264827cb98 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.

The new option "--fsmode String" can be used to control
mounting and unmounting of the fs during resizing.

Possible --fs values:

checksize
  Only applies to reducing size; does nothing for extend.
  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
  Resize the fs using the fs-specific resize command.
  This may include mounting, unmounting, or running fsck.
  See --fsmode to control mounting behavior, and --nofsck to
  disable fsck.

resize_fsadm
  Use the old method of calling fsadm to handle the fs
  (deprecated.) Warning: this option does not prevent lvreduce
  from destroying file systems that are unmounted (or mounted
  if prompts are skipped.)

ignore
  Resize the LV without checking for or handling a file system.
  Warning: using ignore when reducing the LV size may destroy the
  file system.

Possible --fsmode values:

manage
  Mount or unmount the fs as needed to resize the fs,
  and attempt to restore the original mount state at the end.

nochange
  Do not mount or unmount the fs. If mounting or unmounting
  is required to resize the fs, then do not resize the fs or
  the LV and fail the command.

offline
  Unmount the fs if it is mounted, and resize the fs while it
  is unmounted. If mounting is required to resize the fs,
  then do not resize the fs or the LV and fail the command.

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.
