Make it easy to switch an array's content type without loosing its size information.

Fixes recompilation of all affected methods by also checking the #callback: pragma. (See FFI-Callbacks)

  recompileAllLibraryFunctions
  "Recompile all methods that do FFI calls (e.g. <apicall ... > or <cdecl ... >) to update all mappings from type name to atomic type and struct type. Note that unknown struct types will be created on-the-fly and can later be completed by defining fields in the particular structure class via #defineFields or #compileFields. Note that such a recompilation is especially useful if 'type constants' for atomic types to additional dispatch such as according to the current platform's #wordSize."
