Refactor flags in method FileSystem::execute_command() (#754684)
Change the two optional boolean parameters into a single optional flags
parameter which uses symbolically defined names. Makes reading the
execute_command() calls much easier to understand. (Implemented as bit
field using the same technique as used for Glib::SpawnFlags [1]).
This changes the calls thus:
execute_command(cmd, od) -> (cmd, od)
execute_command(cmd, od, false) -> (cmd, od, EXEC_NONE) // [2]
execute_command(cmd, od, true ) -> (cmd, od, EXEC_CHECK_STATUS)
execute_command(cmd, od, false, true) -> (cmd, od, EXEC_CANCEL_SAFE)
execute_command(cmd, od, true , true) ->
(cmd, od, EXEC_CHECK_STATUS|EXEC_CANCEL_SAFE)
[1] SpawnFlags bitwise operators in
/usr/include/glibmm-2.4/glibmm/spawn.h.
[2] False and EXEC_NONE are the default values for the optional third
parameter before and after this change respectively and both mean
the same. This is being used in btrfs::resize() and being kept for
now despite it being the default.

Time and check nearly all file system action commands (#754684)
There has been an undocumented rule that external commands displayed in
the operation details, as part of file system manipulations, only get a
time and check mark displayed when multiple commands are needed, and not
otherwise. (GParted checks whether all commands are successful or not
regardless of whether a check mark is displayed in the operation details
or not).
EXCEPTION 1: btrfs resize
Since the following commit [1] from 2013-02-22, GParted stopped
displaying the timing for the btrfs resize command in the operation
details. It being part of a multi-command sequence to perform the step.
This is because FileSystem::execute_command() since the commit can only
check the exit status for zero / non-zero while timing and checking the
command status but btrfs resize needs to consider some non-zero statuses
as successful.

EXCEPTION 2: ext2/3/4 move and copy using e2image
When use of e2image was added [2] the single command steps were timed
and check.

Use e2image to move/copy ext[234] file systems (#721516)
EXCEPTION 3: fat16/32 write label and UUID
Uses Utils::execute_command() rather than FileSystem::execute_command()
so can be separately changed. See the following commit for resolution
of the final commands not yet timed and check mark displayed.
CHANGE:
Lets make a simpler rule of always displaying the time and a check mark
for all external commands displayed in the operation details. However
this makes several of the other single command actions need special exit
status handling because zero success, non-zero failure is not correct
for every case. Specifically affects resizing of reiserfs and check
repair of ext2/3/4, fat16/32, jfs and reiserfs.
After this change all external commands run as file system actions must
follow one of these two patterns of using the EXEC_CHECK_STATUS flag or
separately calling FileSystem::set_status() to register success or
failure of the command:
exit_status = execute_command(cmd, od, EXEC_CHECK_STATUS...);
or:
exit_status = execute_command(cmd, od, ...);
bool success = (exit_status == 0 || exit_status == OTHER_SUCCESS_VALUE...);
set_status(od, success );
