Upgrade time to 0.2.5 (#1254)

* Use `OffsetDateTime` instead of `PrimitiveDateTime`

* Parse time strings with `PrimitiveDateTime::parse` instead of `OffsetDateTime::parse`

* Remove unused `time` dependency from actix-multipart

* Fix a few errors with time related tests from the `time` upgrade

* Implement logic to convert a RFC 850 two-digit year into a full length year, and organize time parsing related functions

* Upgrade `time` to 0.2.2

* Correctly parse C's asctime time format using time 0.2's new format patterns

* Update CHANGES.md

* Use `time` without any of its deprecated functions

* Enforce a UTC time offset when converting an `OffsetDateTime` into a Header value

* Use the more readable version of `Duration::seconds(0)`, `Duration::zero()`

* Remove unneeded conversion of time::Duration to std::time::Duration

* Use `OffsetDateTime::as_seconds_f64` instead of manually calculating the amount of seconds from nanoseconds

* Replace a few additional instances of `Duration::seconds(0)` with `Duration::zero()`

* Truncate any nanoseconds from a supplied `Duration` within `Cookie::set_max_age` to ensure two Cookies with the same amount whole seconds equate to one another

* Fix the actix-http::cookie::do_not_panic_on_large_max_ages test

* Convert `Cookie::max_age` and `Cookie::expires` examples to `time` 0.2

Mainly minor  changes. Type inference can be used alongside the new
`time::parse` method, such that the type doesn't need to be specified.
This will be useful if a refactoring takes place that changes the type.
There are also new macros, which are used where possible.

One change that is not immediately obvious, in `HttpDate`, there was an
unnecessary conditional. As the time crate allows for negative durations
(and can perform arithmetic with such), the if/else can be removed
entirely.

Time v0.2.3 also has some bug fixes, which is why I am not using a more
general v0.2 in Cargo.toml.

v0.2.3 has been yanked, as it was backwards imcompatible. This version
reverts the breaking change, while still supporting rustc back to
1.34.0.

* Add missing `time::offset` macro import

* Fix type confusion when using `time::parse` followed by `using_offset`

* Update `time` to 0.2.5

* Update CHANGES.md
