[PATCH v4 14/16] fuzz: add general-fuzz configs for oss-fuzz

[Alexander Bulekov]

Predefine some general-fuzz configs. For each of these, we will create a
separate FuzzTarget that can be selected through argv0 and, therefore,
fuzzed on oss-fuzz.

Maybe this isn't the best way to specify a list string-triples. I saw
that some files use QLIT_QDICT for purposes that seem similar, however I
don't think that plays well with multi-line strings. Does anyone have a
better suggestion?
