Make fuzzing with meson build work
TL;DR: Update build system and utility script such invoking
`build-aux/oss-fuzz.sh` is all that's needed to build fuzzers in an OSS-Fuzz
compatible environment.
`.gitlab-ci.yml`: Build three variants of fuzzers: using autoconf as before,
libFuzzer via Clang and using the standalone driver.
`build-aux/oss-fuzz.sh`: Remove compiler-specific code. The fuzzing environment
should control the compiler via `$CC`/`$CXX` along with flags in
`$CFLAGS`/`$CXXFLAGS`. Make code actually build by overriding `b_lundef` default
value, otherwise fuzzing-related symbols would cause linker errors during
compilation. Pass fuzzing engine via option; the default would be to use the
built-in standalone engine.
`meson.build`: Remove all fuzzing-related logic except to detect whether fuzzing
should be enabled at all.
`fuzzing/meson.build`: If fuzzing engine `standalone` is selected the build
behaves as any other C program build. When another fuzzing engine is to be used,
e.g. from `$LIB_FUZZING_ENGINE` in `build-aux/oss-fuzz.sh`, a test program is
compiled and linked to ensure that linking suceeds (in particular whether
a `main` function is provided). Prepare for the addition of more fuzzing
binaries by using a loop. Add OSS-Fuzz configuration file for binaries.
