Feature #9549: Improvements to Time::strptime

----------------------------------------
I opened [a pull request on GitHub](https://github.com/ruby/ruby/pull/540) a few days ago but wanted to open a parallel issue here, since I think this is the preferred tracker.

This patch includes three commits:

* Add default arguments to `Time::strptime` to match `Date::strptime`. After this patch, `Time::strptime` may be invoked with 0, 1, or 2 arguments. When invoked with 0 or 1, it produces a result equivalent to `Date::strptime` invoked with the same arguments.
* Raise ArgumentError if time passed to `Time::strptime` is invalid. This fixes a Ruby bug and adds a test to ensure it will not regress. Before this commit:

    require 'date'
    Date::strptime('31/02/2014', '%d/%m/%Y') # ArgumentError: invalid date
    require 'time'
    Time::strptime('31/02/2014', '%d/%m/%Y') # 2014-03-03 00:00:00 +0000

* I have also renamed variables in `Time::parse` to be consistent with the changes I made to `Time::strptime`. Specifically, renaming `d` to `hash`, since it is not a `Date` and renaming the `date` parameter to `time`. I believe both of these changes make the code clearer.

Thank you for considering this patch.
