Nik Bougalis 9930b12d9d Beast clean up:
* Remove binding, dispatch handling and exit hooks in favor
  of std alternatives; remove crash-handling infrastructure,
  error message framework, system-specific process handling
  and Objective-C interop helpers.
* Simplify Beast function profiling
* Simplify beast::Time interface
* Simplify beast::String interface
* Simplify beast::File interface
