AtomicHashMap.h was a pair of C++ templates. Common/AtomicMap.{h,c}
replaces it with the same structure in C89, keyed by bytes: each key's
node is pushed at its bucket's head with a CAS and stays until the map
is freed.
- atomic_slot_map: one atomic pointer slot per key, for the OGL
pipeline programs (keyed by the PipelineProgramKey bytes) and the
D3D state cache (keyed by each state's hex word).
- atomic_value_map: values that begin with a quiesce_node_t, published
whole and freed once no reader is inside, for the asset library's
id-to-files and path-to-id maps (keyed by the string's bytes).
The OGL program cache's reference count and shader id counter move to
retro_atomic too, and PipelineProgramKeyHash goes with the template
that used it.
