Introduce method wrappers for quick_symbol_functions

This introduces wrappers for each function in quick_symbol_functions.
The wrappers are methods on objfile, and are defined in
symfile-debug.c, so that they can use the symfile_debug variable.
Places that call the quick functions are all updated to call these new
wrapper methods.
