Subject: parted: Add '--ignore-busy' option
References: bsc#1058667
Patch-mainline: not yet, based on v3 submitted on 2017-11-07
There are dangerous actions like e.g. shrinking or removing a busy
partition which should be possible in script mode but not without
using an option to enforce that. This is meant to prevent buggy
scripts from doing those actions unintentionally.
Also add proper printing of the help text for a long option without
a short option.

Subject: parted: Fix resizepart and rm command
References: bsc#1058667
Patch-mainline: not yet, based on v3 submitted on 2017-11-07
In script mode the resizepart command fails when shrinking and
if the partition is busy. Also the warnings printed in this
case are only applicable to interactive mode. A similar problem
exists with the rm command.
So print different warnings in script mode and continue if growing
a busy partition. Require the '--ignore-busy' option to be set in
order to shrink or remove a busy partition. Shrinking cannot be
more dangerous in script mode than removing. So allow shrinking a
partition in script mode which is not busy.
In interactive mode there is a problem if providing the partition
number and the end of the partition as arguments to the resizepart
command directly with a busy partition. The warning is shown and
after continuing anyway parted asks for the partition end although
it has already been provided. So count the number of words on
command line and warn after processing all of them or after getting
the partition number.
