This commit adds support for passing additional url options along
with a :status option and any of the flash-related options to
`redirect_to` (i.e. :flash, :alert & :notice).

Closes #7570.

The `force_ssl` command now builds the redirect url from `request.fullpath`.
This ensures that the format is maintained and it doesn't redirect to a route
that has the same parameters but is defined earlier in `routes.rb`. Also any
optional segments are maintained.

Fixes #7528.
Fixes #9061.
Fixes #10305.

Move method used only in the test to the test code itself

refactor number helper

It's simpler to assume that passed env is just a string without any
extensions, especially when DatabaseTasks are intended to be used also
without rails.

Serialized column should not be wrapped twice. Fix #10067.

This is a public class, which could be used directly in order to allow
easier database management. Now it also contains settings, which will be
used by databases.rake.

This will allow to set fixtures path in global config easier, it should
be not needed to use FIXTURES_PATH every time user wants to load
fixtures.

This fixes issue #10066

Remove code duplication

Moved the check for the rails test environment into rails.rb

Closes #10238

Trying to lookup the parent class when the association is being built
runs the risk of generating uninitialized constant errors because
classes haven't been fully defined yet. To work around this we look up
the class at runtime through the `association` method.

Fixes #10197.

ActiveRecord having clause bug fix

refactor initialization of array

The changes in b79adc43 had a bug where if the time in the String
was in standard time but the current time was in daylight savings then
the calculated adjustment was off by an hour.

This commit fixes this and adds extra tests for the following:

* time in string is standard time, current time is standard time
* time in string is standard time, current time is daylight savings
* time in string is daylight savings, current time is standard time
* time in string is daylight savings, current time is daylight savings

Fixes #10306.
