[binutils-gdb] Rename _const functions to use overloading instead


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=f1735a53a63040cc4b4a735bf18a3f20d308e519

commit f1735a53a63040cc4b4a735bf18a3f20d308e519
Author: Tom Tromey <tom@tromey.com>
Date:   Sun Sep 10 14:19:19 2017 -0600

    Rename _const functions to use overloading instead
    
    This renames a few functions -- skip_spaces_const,
    skip_to_space_const, get_number_const, extract_arg_const -- to drop
    the "_const" suffix and instead rely on overloading.
    
    This makes future const fixes simpler by reducing the number of lines
    that must be changed.  I think it is also not any less clear, as all
    these functions have the same interface as their non-const versions by
    design.  Furthermore there's an example of using an overload in-tree
    already, namely check_for_argument.
    
    This patch was largely created using some perl one-liners; then a few
    fixes were applied by hand.
