Adds support for tracing
mmap
s in native code and logging that. Notably does not let us calllibc::mmap(..)
on the Rust side and thenmunmap
it on the native side / the other way; I have ideas for maybe doing that, but they'd be quite a bit more involved since it requires us doing some syscall shimming.
