fix bad test by making number that fits for integer

PR https://github.com/rails/rails/pull/10566 had to be reverted
because after applying the fix test
"test_raise_record_not_found_error_when_invalid_ids_are_passed"
started failing.

In this test invalid_id is being assigned a really large number
which was causing following failure when PR #10566 was applied.

```
RangeError: bignum too big to convert into `long long'
SELECT  `interests`.* FROM `interests`
WHERE `interests`.`man_id` = ? AND `interests`.`id` = ?
LIMIT 1  [["man_id", 970345987], ["id", 2394823094892348920348523452345]]
```

This test is not failing in master because when test code
`man.interests.find(invalid_id)` is executed then interests
are fully loaded in memory and no database query is executed.

After PR #10566 was merged then test code
`man.interests.find(invalid_id)` started executing sql query
and hence the error.

In case someone is wondering why the second part of query is not
failing, then that's because the actual query does not require
any variable substituation where the number is large. In that
case the sql generate is following.

```
SELECT `interests`.* FROM `interests`
WHERE `interests`.`man_id` = ? AND `interests`.`id`
IN (8432342, 2390102913, 2453245234523452)  [["man_id", 970345987]]
```

Backport #11033 to master

Since docrails as moved from lifo/docrails to rails/docrails we have
to ask for commit rights or submit patches directly to the rails
repository

Previously when app was mounted as following:

    class Foo
      def call(env)
        [200, {}, [env['PATH_INFO']]]
      end
    end

    RackMountRailsBug::Application.routes.draw do
      mount RackTest.new => "/foo"
    end

trailing slash was removed from PATH_INFO. For example requesting

    GET /foo/bar/

on routes defined above would result in a response containing "/foo/bar"
instead of "/foo/bar/".

This commit fixes the issue.

(closes #3215)

Fix BacktraceSilencer#noise when multiple silencers are configured

Extract ActionView to separate directory

Tests for bug in sprocket-rails:
  do not use value of configuration options
  which changed after environment loaded

Now if somebody by mistake will remove malformed files test will raise error.

The previous implementation of BacktraceSilencer#noise did not
work correctly if more than one silencer was configured --
specifically, it would only return noise which was matched by all
silencers.

The new implementation is such that anything that has been matched by
silencers is removed from the backtrace using Array#- (array
difference), ie. we now return all elements within a backtrace that
have been matched by any silencer (and are thus removed by #silence).

Fixes #11030.

They were moved to actionview/ and are not used in actionpack

ActionView still relies on ActionPack in some of the tests.

This commit creates structure for Action View gem and is first of a
series of commits extracting Action View from Action Pack.
