We used to just log libparted exceptions without handling them. This patch
changes the exception handler to display a modal dialog box and return the
chosen action to libparted.
The call to "blkid -c /dev/null" on Precise Pangolin Alpha 1 takes
exceedingly long. This occurs when the BIOS is incorrectly set to
indicate a floppy drive is present when none is physically installed.
Use cached blkid results instead.

Setting the status and controlling the timing of operation details
initialised with OperationDetail(desc, status, font) uses a conditional
branch depending on the uninitialised variable this->status.

Requires libparted 2.4 or higher, or blkid from utils-linux 2.20 or
higher for nilfs2 file system detection.
Requires nilfs-utils for nilfs2 file system support.
Closes Bug #642842 - nilfs is not detected
When GParted performed operations or combinations of operations,
such as:
a) copy to same or smaller size destination partition
b) move to same or smaller size due to alignment change
c) resize to smaller size
a redundant maximize file system operation would occur.
Normally these redundant maximize operations to grow the file
system to take up all the space in the partition were not harmful.
However in situations where libparted failed to inform the kernel
of partition changes, then the extra maximize operation would
grow the file system to be the original partition size. In cases
where the original partition was larger than the new partition
size, this caused problems because the file system would be
larger than the partition on reboot.
This enhancement avoids redundant file system maximize actions on
copy, move, and resize, and should help reduce problems described
in the following links:

Btrfsctl and btrfs-show were depreciated in October 2011 and have been
superseeded by the newer btrfs multi-tool control command. Use btrfs as
first choice, falling back to btrfsctl and btrfs-show when not found.
There are still 2 issues with reading btrfs labels when falling back
on using btrfs-show command, rather than primary method of using the
blkid command:
1) Label is set no "none" when btrfs-show is reporting there is no
label, although it is impossible to distinguish from the case of the
label actually being set to "none".
2) The label has 2 trailing spaces appended as the regular expression
matches "Label: (btrfslabel )uuid:" rather than
"Label: (btrfslabel) uuid:" in the btrfs-show output.
Assume a label "none" means there is no label and fix the regular
expression.
Note that this enhancement changes GParted to first try the native
tools to determine the volume label for all file systems. If the
volume label is not found then the fall back method is to use blkid.
There is a small degradation in device refresh times as a result of
this change.
