6a140a2cb3 script engine: improper string-to-number conversion for negative numbers 
Thanks to Stephen Workman for providing a very detailled hint of the
problem and root cause. This patch bases on his recommendation for a
fix.

0d0ff11991 config: implement function parse_json() 
It is useful to be able to parse arbitrary JSON strings without the need
of an external message modification module. For example, together with
    https://github.com/rsyslog/rsyslog/issues/1977
this can be used to parse out specific fields from Amazon AWS
configuration info. There are also other ample uses for such functionality.

ce06bba15c RainerScript: implement previous_action_suspended() function 
This function returns a boolean indicating if the previous action is
suspended (0 - no, 1 - yes). This is useful if arbitrary processing
(other than calling actions) should be made depending on that state.
A prime example for this is probably calling a ruleset.

b63d3051bc RainerScript: add function script_error() and error-reporting support 
This permits script functions that could fail to report errors back, so
that the user can handle them if desired. We use an errno-style of
interface. That means script_error() needs to be called after functions
that supports it. It will return either 0 (all OK) or something else
(an error condition).

The commit also modifies the parse_time() function to use the new
interface. First of all, this is useful for users, and secondly we
needed a capability to craft a testbench test.

f6f569651c rainerscript: check that we really do not have mem leak via assert() 
This is done because a) it is generally a good idea to have it and
b) we investigate CID 185385 which looks much like a false positive.

e2767839bc rainescript: set/unset statement do not check variable name validity 
Only JSON-based variables can be use with set and unset. Unfortunately,
this restriction is not checked. If an invalid variable is given
(e.g. $invalid), this is not detected upon config processing on
startup. During execution phase, this can lead to a segfault, a
memory leak or other types of problems.
