Change ada_catchpoint::excep_string to be a std::string

This changes ada_catchpoint::excep_string to be a std::string and then
fixes up all t he users.

This found a memory leak in catch_ada_exception_command_split, where
"cond" was copied but never freed.

I changed the type of the "cond_string" argument to
catch_ada_exception_command_split to follow the rule that out
parameters should be pointers and not references.

This patch enables the removal of some cleanups and also the function
ada_get_next_arg.
