They were used like global variables.  Now they are moved to the
functions that actually use them to make clearer how the data flow is.

Mike Fleetwood 01150758c3 Make mounted partition usage method selectable per file system (#683255)
Each file system class can now choose how the size and free space of the
file system is determined when it is mounted.

    .fs.online_read = FS::NONE  (default)
        Do nothing.  Don't get the file system size and free space.

    .fs.online_read = FS::GPARTED
        Use internal GParted method which calls statvfs() system call on
        the mounted file system.

    .fs.online_read = FS::EXTERNAL
        Call the file system's member function set_used_sectors().  This
        is the same function as called when the file system is not
        mounted.   It can determine if the file system is mounted or not
        by testing partition.busy and acting accordingly.

This means that determining the size and free space of active LVM2
Physical Volumes is no longer a special case.  Instead the lvm2_pv class
just elects to have its set_used_sectors() method called for both the
active and deactive cases.

Bug #683255 - ext2: statvfs differs from dumpe2fs (x MB unallocated
              space within the partition)

Mike Fleetwood ee49891611 Disallow resizing of LVM2 PVs which are members of exported VGs (#670171)
When an inactive LVM2 Volume Group is exported it makes it unknown to
the local system, ready for moving the member Physical Volumes to
another system, where the VG can be imported and used.  In this state a
PV can't be resized.

    # lvm pvresize /dev/sda10
      Volume group Test-VG1 is exported
      Unable to read volume group "Test-VG1".
      0 physical volume(s) resized / 1 physical volume(s) not resized
    # echo $?
    5

Fix this by preventing resizing of such a PV.  This has been coded in a
generic way using new function filesystem_resize_disallowed() to
determine whether a file system is allowed to be resized or not.  For
a file system which can be resized, but is currently not allowed to be
resized, the behaviour is as follows:

1)  Pasting into unallocated space is limited to creating a new
    partition which is the same size as the copied partition.

2)  Resizing the partition is disallowed, only moving the partition is
    allowed.

3)  Pasting into an existing partition will only copy the file system.
    If the destination partition is larger a warning will report that
    growing the file system is not currently allowed.

4)  Checking a partition will also report a warning that growing the
    file system is not currently allowed.

This is exactly the same behaviour as for a file system which does not
implement resizing, except for a different warning message.

Mike Fleetwood 795a92f5b2 Add file system specific remove() methods (#670171)
This commit only adds a remove() method to every file system and an
optional call to it in the relevant operations.  All remove() methods
are no operations and not enabled.

The remove() method provides explicit controlled removal of a file
system before the partition is deleted or overwritten by being formatted
or pasted into.  When implemented, it appears as an extra step in the
relevant operation.  The file system specific remove() method is
explicitly allowed to fail and stop the operations currently being
applied.

This is different to the existing erase_filesystem_signatures() which
wipes any previous file system signatures immediately before a new file
system is written to ensure there is no possibility of the partition
containing two or more different file system signatures.  It never fails
or reports anything to the user.

NOTE:
Most file systems should NOT implement a remove() method as it will
prevent recovery from accidental partition deletion.

Curtis Gedak 0fda1d011d Enable new fs resize library available with parted-3.1 (#668281)
The parted-3.1 release brings back FAT16/FAT32 and HFS/HFS+ file
system resize capabilities in a new libparted fs resize library.

The following operations are again available when GParted is linked
with parted-3.1:

   FAT16 - grow and shrink
   FAT32 - grow and shrink
   HFS   - shrink
   HFS+  - shrink

Note that there is a difference in how move actions are handled for
FAT16/FAT32 file systems based on parted version.

When GParted is linked with parted >= 3.0:

   FAT16 - move performed internally by GParted
   FAT32 - move performed internally by GParted

When GParted is linked with parted < 3.0:

   FAT16 - move performed by libparted
   FAT32 - move performed by libparted

Thanks goes to Jim Meyering for restoring these file system resizing
capabilities in Parted 3.1 with a new libparted fs resize library.

Closes Bug #668281 - minimal file-system resize API? (FAT and HFS*
                     only)

Rogier Goossens 9e96159bb2 Add support for setting UUID (#667278)
Add the ability to set a new random UUID on file systems that provide
the appropriate tools to perform this action.

Update the help manual to include this new functionality.  Also add
reference links to "setting a partition label" and "changing a
partition UUID" in the "copying and pasting a partition" section.

This patch does not include setting the UUID on an NTFS file system.

Curtis Gedak 8a58b5b53e Enable compile and link with libparted 3.0 (#651559)
The release of (lib)parted 3.0 includes a change to the Application
Programing Interface - API.  Most importantly, libparted 3.0 removes
many file system specific function calls, and hence the capabilities
provided by these functions.  In order for GParted to compile and link
with libparted 3.0, this libparted functionality is lost.

Specifically, the functionality that is lost when GParted is compiled
and linked with libparted 3.0 is as follows:

  - Loss of ability to grow and shrink FAT16 and FAT32 file systems
  - Loss of ability to shrink HFS and HFS+ file systems
  - Loss of ability to determine used and unused sectors in HFS and
      HFS+ file systems
  - Loss of ability to erase file system signatures on partition
      create and format

It is hoped that other free software projects will include some or all
of the above lost functionality, which can then be added back to
GParted.

This commit includes a change in how FAT16 and FAT32 file systems are
moved.  Specifically the move is now performed internally by GParted
when linked with libparted 3.0.  The move functionality is provided by
libparted for prior libparted versions (e.g. less than 3.0).

This is the final enhancement in a series of commits that enable
GParted to compile with libparted version 3.0.

Closes Bug #651559 - Doesn't compile against parted 3.0

Make align to MiB the default setting instead of align to cylinder.

Migrate logic for alignment to cylinder into its own method
snap_to_cylinder, and place common logic in snap_to_alignment.

Add alignment checks for situations where space is needed for Master
Boot Record or Extended Boot Record.

Adjust ranges on spin buttons according to required boot record space.

Copy fix for off by one sector (#596552) from
Dialog_Partition_New::Get_New_Partition to
Dialog_Base_Partition::Get_New_Partition

Enhance resize / move logic for checking locations of nearby logical
partitions to not depend on the partition ordering.

Note: This commit does not include limiting graphic movement according
to required boot record space.
