Automatically register FFI functions (dlsym path) #457
Description
Currently anyone using the FFI must arrange for foreign function implementations to be registered with the vm. This should be automatic and provided in two ways:
- The Plasma compiler generates foreign code to do this (Automatically register FFI functions (static linking) #456 )
- The Runtime uses dlsym to find foreign functions.
This bug will implement the second. This can be deferred to a later goal.
