gdb: Convert la_filename_extensions to a method

Browse Source 
Convert language_data::la_filename_extensions member variable to a
virtual method language_defn::filename_extensions.

The new method returns a vector of filename extensions, which means
that where previously we needed a NULL marker on the end of the list,
we can now discard this.

All of the old arrays that contained the extensions now become static
data within each languages filename_extensions method.

I've updated the single use of the filename_extensions method to make
use of this method returning a vector.  And, just in case anyone
accidentally adds a NULL marked into a languages extensions list, I've
added a new assert in add_filename_language (symtab.c) to catch this.

	ada_language::filename_extensions.
