gallium,clover: add OpenCL interoperability support for CL events

v2: - move interop.cpp to clover/api
    - change intptr_t to void* in the interface
    - add a virtual function fence() to simplify some code

v3: - use bool in the interface
v4: - enclose the last two interop functions in try..catch
