* check_disk: Fail on missing arguments for --warning and --critical
* Add new test function for percentage expressions and use it in check_disk
* Add error abort in tests if they fail to parse output
* Fix typo in test which probably broke the test since forever :-(
* check_ssh: properly parse a delayed version control string
This resolves an issue with SSH servers which do not respond with their
version control string as the first thing in the SSH protocol version
exchange phase after connection establishment.
This patch also makes sure that we disregard a potential comment in the
version exchange string to avoid nonsense mismatches. In the future, we
might want to add the capability to match against a user specified comment.
In addition, the patch largely improves the communication towards the
server, which adds better protocol adherence.
Of course, new test cases are added to support the trigger and guard
against regressions of the bugs solved by this patch.

* check_ssh: Handle non-alpha software versions
This patch fixes a bug where we would reject version control strings
that do not contain letters, because the assumption is made that they
always do. This is not required by the RFC however, and there exist
implementations that do not contain letters.
I've also added a few references to the RFC to make the process of
parsing the control string more apparent.

* check_disk increase alert precision
Free disk percentage value was rounded to a full integer meaning it alerted about ~1% percent too early. This is about 10GB on a 1TB disk.
The warning and critical thresholds already support float values, so just the percentage calculation needs to be improved.

* check_disk: adjust test case to support float precision
Using --ignore-missing together with regex matching and ignore option lead
to a wrong error message.
./check_disk -n -w 10% -c 5% -W 10% -r /dummy -i /dummy2
DISK UNKNOWN: Paths need to be selected before using -i/-I. Use -A to select all paths explicitly
The use case here is a cluster with fail-over mounts. So it is a valid situation that
the regex match does not find anything in addtition with a ignore which also does not exist.
After this patch:
./check_disk -n -w 10% -c 5% -W 10% -r /dummy -i /dummy2
DISK OK - No disks were found for provided parameters|
