The exact inspect output of a BigDecimal is out of scope for what we're trying
to communicate about `dup` and `duplicable?` here.
Adding two examples distracts is disctracting, so keep the docs from before
since our minimal version is Ruby 2.2.2.

The Numeric extensions like 1.day, 1.month, etc. shouldn't know
how the internals of ActiveSupport::Duration works.

durations from code
ActiveSupport::Duration.parse('P3Y') == 3.years # It should be true
Duration parsing made independent from any moment of time:
Fixed length in seconds is assigned to each duration part during parsing.
Changed duration of months and years in seconds to more accurate and logical:
1. The value of 365.2425 days in Gregorian year is more accurate
as it accounts for every 400th non-leap year.
2. Month's length is bound to year's duration, which makes
sensible comparisons like `12.months == 1.year` to be `true`
and nonsensical ones like `30.days == 1.month` to be `false`.
Calculations on times and dates with durations shouldn't be affected as
duration's numeric value isn't used in calculations, only parts are used.
Methods on `Numeric` like `2.days` now use these predefined durations
to avoid duplicating of duration constants through the codebase and
eliminate creation of intermediate durations.

Actually, private methods cannot be called with `self.`, so it's not just redundant, it's a bad habit in Ruby

Ruby 2.4.0 has trouble duplicating certain symbols created from
strings via `to_sym`.
It didn't happen with `'symbol'.to_sym.dup` for some reason, but
works fine with the longer string sample.
Once a newer Ruby version with a fix is released we'll get have
a failing test case we can fix.

This behavior changed in Ruby starting with 2.3.0, as a result of
https://bugs.ruby-lang.org/issues/11360. This results in a change in
behavior of these methods which is likely undesirable.

Fix copy_time_to: Copy nsec instead of usec

`copy_time_to` is a helper function for date and time calculations.
It's being used by `prev_week`, `next_week` and `prev_weekday` to keep
the time fraction when jumping around between days.
Previously the nanoseconds part was lost during the operation. This
lead to problems in practice if you were using the `end_of_day`
calculation. Resulting in the time fraction of `end_of_day` not being
the same as next week's `end_of_day`.
With this fix `copy_time_to` doesn't forget the `nsec` digits.

This is a follow up to #25681, specifically this comment:
https://github.com/rails/rails/pull/25681#issuecomment-238294002
The way the thread local variable is stored is an implementation detail
and subject to change. It makes no sense to only generate a reader or
writer as you'd have to know where to read from or where it writes to.

The methods Hash#transform_values and Hash#transform_values! have been
implemented in Ruby and they'll be available as part of the standard
library.
Here's the link to the discussion in Ruby's issue tracker:
https://bugs.ruby-lang.org/issues/12512
These methods are implemented in C so they're expected to perform
better.

In #25880 we tried to cache localtime to fix the performance
regression but that proved to be difficult due to the fact that
localtime/getlocal can take a utc_offset argument. We tried
caching based on the argument but since the argument can be nil
sometimes that meant that if the TZ environment variable changed
then the cached value for nil became invalid. By moving the
caching to DateAndTime#compatibility we don't have to worry about
arguments since it doesn't take any.
There is a possible edge condition where preserve_timezone is set
to false and the system timezone changes then it could result in
a cached value being incorrect but the only way to fix this would
be to remove all caching and live with the performance issue.

`Date.week_start` does not exist. `Date.beginning_of_week` seems to be correct.
