Create target sections for user-added symbol files.
Add the sections of the symbol files that are provided via
'add-symbol-file' to the set of current target sections.
User-added sections are removed upon notification of free_objfile
when their corresponding object file is deleted.
2013-10-29 Nicolas Blanc <nicolas.blanc@intel.com>
* exec.h (add_target_sections_of_objfile): New declaration.

* symfile.c (add_symbol_file_command): Update current target sections.
(symfile_free_objfile): New function.
(_initialize_symfile): Register observer for free_objfile events.
