Introduce a gdb_ref_ptr specialization for struct value
struct value is internally reference counted and so, while it also has some ownership rules unique to it, it makes sense to use a gdb_ref_ptr when managing it automatically. This patch removes the existing unique_ptr specialization in favor of a reference-counted pointer. It also introduces two other clarifications: 1. Rename value_free to value_decref, which I think is more in line with what the function actually does; and 2. Change release_value to return a gdb_ref_ptr. This change allows us to remove the confusing release_value_or_incref function, primarily by making it much simpler to reason about the result of release_value. gdb/ChangeLog 2018-04-06 Tom Tromey <tom@tromey.com> * varobj.c (varobj_clear_saved_item) (update_dynamic_varobj_children, install_new_value, ~varobj): Update. * value.h (value_incref): Move declaration earlier.
