Comment (by Hello71):

 so it looks like building the shared library is actually the right way to
 go. asan applies only to the shared library in this case, can probably use
 `-Z sanitizer=address` on nightly for rust tests. few hitches:

 1. libtool sucks. currently using meson. would rather we switch to that
 entirely, but not opposed to someone else figuring out how to make
 `libtor.so` (basically `tor` minus `tor_main.c`) using libtool instead

 2. still figuring out how best to link it in; hopefully will not use
 `RUSTFLAGS` so we don't have to recompile all dependencies on each test
