use "enum ruby_tag_type" and TAG_NONE.

Return value of EXEC_TAG() is saved by "int state".
Instead of "int", use "enum ruby_tag_type". First EXEC_TAG()
value should be 0, so that define TAG_NONE (= 0) and use it.

Some code used "status" instead of "state". To make them clear,
rename them to state.

We can change variable name from "state" to "tag_state", but this
ticket doesn't contain it.
