The refactoring allows better reuse of the ELF support and cleans up some hacks from the generic file and archive handling improving the separation of the file handling from the file format, ie ELF. The handling of ELF object files and ELF object files inside archives is cleaner. The refactor cleaned up the symbol handling where the symbols now reside in the ELF file object and references are take in symbol pointer containers and symbol table containers. The main purpose of the refactor is to allow support for creating and writing ELF files. Also added an rtems-syms command where special symbol support can be added.
