[PATCH 08/10] Remove coff_symfile_init

[Tom Tromey <tromey@adacore.com>]

coff_symfile_init is an empty function, and rather than give it a
name, just use a lambda in coff_sym_fns.

I've occasionally considered adding a do_nothing template function for
all our empty function needs, but still haven't bothered.
