TimeZone#to_s shows offset as GMT instead of UTC, because GMT will be more familiar to end users (see time zone selects used by Windows OS, google.com and yahoo.com.) Reverts [8370]

Previously, the code collecting watch_frames could fail leaving
watch_frames defined but nil. The cleanup code checks watch_frames
is defined, but not that it holds a value, raising an undefined method
on NilClass error rather than the original cause.  This can make
debugging the underlying cause a total pain.

Hash.from_xml: datetime xml types overflow to Ruby DateTime class when out of range of Time. Adding tests for utc offsets

Adding Date.current, which returns Time.zone.today if config.time_zone is set; otherwise returns Date.today. ActionView date_helper uses Date.current to determine locale-appropriate default

TimeWithZone: date part getter methods (#year #mon #day etc) are defined on class; no longer relying on method_missing

Time.zone.parse: compatibility with far future date with time zone offset in string. Eliminate creation of additional TimeWithZone instance to determine utc offset.

Fix Time.zone.parse from stripping time zone information and make Time aware attribute methods use Time.zone.parse instead of to_time

Add ActiveSupport::Deprecation::DeprecatedInstanceVariable class to
deprecate instance variables of primitive types such as stings.

Duration #since and #ago with no argument (e.g., 5.days.ago) return TimeWithZone when config.time_zone is set. Introducing Time.current, which returns Time.zone.now if config.time_zone is set, otherwise just returns Time.now

Bundling abbreviated version of TZInfo gem 0.3.8: only the classes and zone definitions required to support Rails time zone features are included. If a recent version of the full TZInfo gem is installed, this will take precedence over the bundled version
