We used to generate a module T with a serialize() and deserialize() fn,
but this was suboptimal for a number of reasons:
- it required moving serialization into core so that uint etc worked
- it was harder to override the serialization behavior locally
(this is now trivial)
- Move io, run and rand to core.
- Remove incorrect ctypes module (use libc).
- Remove os-specific modules for os and fs.
- Split fs between core::path and core::os.
This makes it possible to move them between crates without confusion,
and to instantiate them at a point where the monomorphizing
substitutions are known.
Issue #1944
This required changing almost all users of hashmaps to import the hashmap interface first.
The `size` member in the hashmap structure was renamed to `count` to work around a name conflict.
