History
Omar Sandoval f20b41c8c0 Allow naming and configuring order of symbol finders 
Currently, the bare-bones add_symbol_finder() interface only allows
adding a symbol finder that is called before any existing finders. It'd
be useful to be able to specify the order that symbol finders should be
called in and to selectively enable and disable them. To do that, we
also need finders to have a name to identify them by. So, replace
add_symbol_finder() (which hasn't been in a release yet) with a set of
interfaces providing this flexibility: register_symbol_finder(),
set_enabled_symbol_finders(), registered_symbol_finders(), and
enabled_symbol_finders(). Also change the callback signature to take the
program.

In particular, this flexibility will be very useful for a plugin system:
pre-installed plugins can register symbol finders that the user can
choose to enable or disable.
