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.

51c03c66e0 make inline functions C99-compliant 
As it seems, different C compilers have different rules/interpretations
on inline functions. The current code base did not properly obey all C99
rules. We fix this by converting some functions to macros and others to
include the necessary C99 plumbing. We also remove some inline attributes
for functions where this seems to be to agressive (aka "function to big").

This fixes build problems in some environments and is a general code
cleanup measure.
