ext/coverage/: add the oneshot mode
This patch introduces "oneshot_lines" mode for `Coverage.start`, which checks "whether each line was executed at least once or not", instead of "how many times each line was executed". A hook for each line is fired at most once, and after it is fired, the hook flag was removed; it runs with zero overhead. See [Feature #15022] in detail. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65195 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
