blackbox fuzzing mechanisms

- support for HALs with nested sub-structures which have another set of
  function pointers
- support 32-bit and 64-bit libraries
- refine the protocol between agent and runner (see vts multi-device
  internals: spec part)
- camera hal (for bullhead) with instrumentation
- camera hal VTS spec files
- camera hal fuzz test case
- utils to coverage-guided whitebox fuzzing
- sample fuzz test case extension for whitebox fuzzing
