Previously, the `posix_internal.h` header needed to be exposed to the application because we had non-trivial details for most posix types (pthread, mutex, cond, ...). Since most of those have been simplified to a typedef'ed integer, we no longer need to expose that header to the applicaiton. Additionally, it means that we can adopt normalized header order in posix. Additionally, keep more implementation details hidden and prefer the static keyword on internal symbols where possible.
