Previously, requiring parsers emitted a number of unused variable and unreachable statement warnings. The unused variable warnings are simple to fix (see 8dd1655), but the unreachable statements do not seem to be. Since it seems like its difficult to make Ragel generated parsers not emit any warnings, this commit adds a helper method that wraps require and silences the warnings emitted. The changes to $VERBOSE in the parsers added in 7ef5694 unfortunately do not help as the warnings are emitted on parse and not when evaluating the files.

Previously, requiring any of the ragel generated parsers in mail would output tons of warnings in tests, making output much harder to read (especially in Railties). This commit extends the RaiseWarnings patch to suppress output from these mail parsers. The suppression can be removed once mikel/mail#1557 or mikel/mail#1551 or any other PR fixes the issue

Summary
Previously, requiring parsers emitted a number of unused variable and unreachable statement warnings. The unused variable warnings are simple to fix (see skipkayhil/mail@8dd1655), but the unreachable statements do not seem to be.
Since it seems like its difficult to make Ragel generated parsers not emit any warnings, this commit adds a helper method that wraps require and silences the warnings emitted. The changes to $VERBOSE in the parsers added in 7ef5694 unfortunately do not help as the warnings are emitted on parse and not when evaluating the files.

If the method is overkill but the approach is reasonable, I can also change this to just add the warning silencing to the individual requires since there are only 16.
