  -----------
  [scudo] Add Scudo support for Trusty OS

trusty.cpp and trusty.h define Trusty implementations of map and other
platform-specific functions. In addition to adding Trusty configurations
in allocator_config.h and size_class_map.h, MapSizeIncrement and
PrimaryEnableRandomOffset are added as configurable options in
allocator_config.h.
