[PATCH v6 13/16] fuzz: add an "opaque" to the FuzzTarget struct

Subject: [PATCH v6 13/16] fuzz: add an "opaque" to the FuzzTarget struct
Date: Wed, 21 Oct 2020 17:09:19 -0400

It can be useful to register FuzzTargets that have nearly-identical
initialization handlers (e.g. for using the same fuzzing code, with
different configuration options). Add an opaque pointer to the
FuzzTarget struct, so that FuzzTargets can hold some data, useful for
storing target-specific configuration options, that can be read by the
get_init_cmdline function.
