There is a new way to do interposing that is more supported/proper. The original darwintrace from the DarwinBuild project has the DARWINTRACE_INTERPOSE macro which shows how to do it.

I assume this still applies even with the major changes in darwintrace I've made? Are there any limitations to which functions can be interposed? I assume we can skip setting DYLD_FORCE_FLAT_NAMESPACE=1 when using interposing?

darwintrace: get rid of deprecated syscall() macro

Since using dyld interposing [1], it is no longer necessary to make
direct syscalls. Instead, the normal library functions can be called.

The syscall() macro is deprecated as of macOS 10.12, so we should get
rid of it.
