Fix typo in "Hello World" template in German

Remove deprecated behavior allowing nested arrays as query values

Active Record defines `attribute_method_suffix :?`. That suffix will
match any predicate method when the lookup occurs in Active Model. This
will make it incorrectly decide that `id_changed?` should not exist,
because it attempts to determine if the attribute `id_changed` is
present, rather than `id` with the `_changed?` suffix. Instead, we will
look for any correct match.

Remove environment dependency for db:schema:load

All of the behavior :environment was giving (that db:schema:load needed)
was provided as well with :load_config.

This will address an issue introduced in
https://github.com/rails/rails/pull/15394. The fact that db:schema:load
now drops and creates the database causes the Octopus gem to have [an
issue](https://github.com/tchandy/octopus/issues/273) during the drop
step for the test database (which wasn't happening in db:schema:load
before). The error looks like:

    ActiveRecord::StatementInvalid: PG::ObjectInUse: ERROR:  cannot drop the currently open database
    : DROP DATABASE IF EXISTS "app_test"

Because of the timing, this issue is present in master, 4-2-*, and
4.1.8.

A note to forlorn developers who might see this: "Additionally" in a
commit message means you should have a separate commit, with a separate
justification for changes. Small commits with big messages are your
friends.

Fix MessageVerifier's #verified in CHANGELOG

[ci skip]

As confirmed by @lleger (the author of `verified`) [in this comment](https://github.com/rails/rails/pull/17727#issuecomment-65488743):

> Actually, it no longer returns false explicitly (bc8cc56a), so I guess the CHANGELOG isn't totally accurate. It returns nil instead (but the functionality isn't practically different).

Prevent Symbol GC

remove misleading class [ci skip]

The method was added in https://github.com/rails/rails/commit/30d21dfcb7fafe49b3805b8249454485a90097b6#diff-5055d9f16b442adb1d2f0f65903a196bR141.
With the method call in https://github.com/rails/rails/commit/30d21dfcb7fafe49b3805b8249454485a90097b6#diff-cc7bb557df2247c0a42bc180fdb6eb05R47.
Later one more method call was added in https://github.com/rails/rails/commit/401787db4bc428dce88b04e343a64c6a6c3b681c#diff-cc7bb557df2247c0a42bc180fdb6eb05R183.
And both method calls were deleted in https://github.com/rails/rails/commit/3df07d093a1e4207caa63fd2e3b67599211f5800#diff-cc7bb557df2247c0a42bc180fdb6eb05L47 and https://github.com/rails/rails/commit/3df07d093a1e4207caa63fd2e3b67599211f5800#diff-cc7bb557df2247c0a42bc180fdb6eb05L189.

Just do `grep -nr 'await_close' .`.

Remove "rescue" clause around "require 'openssl'"

This `# :nodoc:` had the effect of hiding every method that follows.
This meant that the API page for `ActiveRecord::Core` only contained
`configurations` and none of the following methods.

Furthermore this `# :nodoc:` had no effect on `maintain_test_schema`.
Those `mattr_accessor` inside the `included` block are not picked up
by rdoc.

Correct docs for ActiveRecord batching methods [ci skip]

Some `require 'openssl'` statements were surrounded by `rescue` blocks to deal with Ruby versions that did not support `OpenSSL::Digest::SHA1` or `OpenSSL::PKCS5`.

[As @jeremy explains](https://github.com/rails/rails/commit/a6a0904fcb12b876469c48b1c885aadafe9188cf#commitcomment-8826666) in the original commit:

> If jruby didn't have jruby-openssl gem, the require wouldn't work. Not sure whether either of these are still relevant today.

According to the [release notes for JRuby 1.7.13](http://www.jruby.org/2014/06/24/jruby-1-7-13.html):

> jruby-openssl 0.9.5 bundled

which means the above `rescue` block is not needed anymore.

All the Ruby versions supported by the current version of Rails provide those OpenSSL libraries, so Travis CI should also be happy by removing the `rescue` blocks.

Just to confirm, with JRuby:

    $ ruby --version #=> jruby 1.7.16.1 (1.9.3p392) 2014-10-28 4e93f31 on Java HotSpot(TM) 64-Bit Server VM 1.8.0_20-b26 +jit [darwin-x86_64]

And with Ruby 2.1:

    $ ruby --version #=> ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]
