This adds a round trip test for config file generation to the fuzzer.
(the next step after this PR will be a fuzzer that verifies that the
round trip actually matches the results.
This change ended up requiring quite a few minor changes to fix the
ambiguities between the config file generation and config file reader.
1). There was a number of potential conflicts between positional names
and regular option names that could be triggered in config files, this
required a number of additional checks on the positional naming to
ensure no conflicts.
2). flag options with disable flag override can produce output results
that are not valid by themselves, resolving this required flag input to
be able to handle an array and output the original value set of results.
3). strings with non-printable characters could cause all sorts of chaos
in the config files. This was resolved by generating a binary string
conversion format and handling multiline comments and characters, and
handling escaped characters. Note; I think a better solution is to move
to fully supporting string formatting and escaping along with the binary
strings from TOML now that TOML 1.0 is finalized. That will not be this
PR though, maybe the next one.
4). Lot of ambiguities and edge cases in the string splitter, this was
reworked
5). handling of comments was not done well, especially comment characters in the
name of the option which is allowed.
6). non printable characters in the option naming. This would be weird
in practice but it also cause some big holes in the config file
generation, so the restricted character set for option naming was
expanded. (don't allow spaces or control characters).
