devel/ruby-activesupport42: update to 4.2.10

## Rails 4.2.10 (September 27, 2017) ##

*   No changes.

## Rails 4.2.9 (June 26, 2017) ##

*   Fixed bug in `DateAndTime::Compatibility#to_time` that caused it to
    raise `RuntimeError: can't modify frozen Time` when called on any frozen `Time`.
    Properly pass through the frozen `Time` or `ActiveSupport::TimeWithZone` object
    when calling `#to_time`.

    *Kevin McPhillips* & *Andrew White*

*   Restore the return type of `DateTime#utc`

    In Rails 5.0 the return type of `DateTime#utc` was changed to `Time` to be
    consistent with the new `DateTime#localtime` method. When these changes were
    backported in #27553 this inadvertently changed the return type in a patcn
    release. Since `DateTime#localtime` was new in Rails 4.2.8 it's okay to
    restore the return type of `DateTime#utc` but keep `DateTime#localtime` as
    returning `Time` without breaking backwards compatibility.

    *Andrew White*

*   In Core Extensions, make `MarshalWithAutoloading#load` pass through the \ 
second, optional
    argument for `Marshal#load( source [, proc] )`. This way we don't have to do
    `Marshal.method(:load).super_method.call(sourse, proc)` just to be able to \ 
pass a proc.

    *Jeff Latz*

*   Cache `ActiveSupport::TimeWithZone#to_datetime` before freezing.

    *Adam Rice*

*   `AS::Testing::TimeHelpers#travel_to` now changes `DateTime.now` as well as
    `Time.now` and `Date.today`.
