Add fuzzing support to build system LibFuzzer, Honggfuzz and other programs implement simple interfaces for fuzzing appropriately prepared code. Samba contains quite a lot of parsing code, often a good target for fuzzing. With this change the build system is amended to support building fuzzing binaries (added in later changes).

lib/fuzzing: Use --fuzz-target-ldflags if specified This makes integration with oss-fuzz possible. Only the fuzzer binaries should be linked with libFuzzer, not things like asn1_compile, so this can not be done via the global ADDITIONAL_LDFLAGS.

Add fuzzing binary for tiniparser The "tiniparser_load" function is made into a wrapper for the newly added "tiniparser_load_stream" function which accepts a FILE pointer. This way no actual files have to be opened for fuzzing (memfd_create(2) isn't readily available on all systems yet).
