Export symbols defined in the sdk.

This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.

  Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.

  Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:
