*TLDR*: The method is 4 times faster when log level is higher than DEBUG.
Also, the other two methods, `#deliver` and `#receive` have similar guard statements,
so this commit adds some symmetry to the code.
This is probably not the most critical part of ActionMailer in terms
of performance, but here are some benchmarks:
```
require 'benchmark/ips'
require 'action_mailer'
event = ActiveSupport::Notifications::Event.new(
'process.action_mailer',
Time.now,
Time.now,
'bf4e2b36ce085fd35b24',
{ mailer: "UserMailer", action: :welcome }
)
ActionMailer::Base.logger = ActiveSupport::Logger.new '/dev/null'
subscriber = ActionMailer::LogSubscriber.new
def subscriber.process_with_guard(event)
return unless logger.debug?
mailer = event.payload[:mailer]
action = event.payload[:action]
debug("\n#{mailer}##{action}: processed outbound mail in #{event.duration.round(1)}ms")
end
Benchmark.ips do |r|
ActionMailer::Base.logger.level = ::Logger::Severity::INFO
r.report('no guard') { subscriber.process(event) }
r.report(' guard') { subscriber.process_with_guard(event) }
end
__END__
Calculating -------------------------------------
no guard 9640 i/100ms
guard 38381 i/100ms
-------------------------------------------------
no guard 169166.9 (±10.2%) i/s - 838680 in 5.007262s
guard 728184.9 (±9.6%) i/s - 3607814 in 4.999218s
```
When log level is DEBUG, the _guarded_ method is a bit slower. This is a
good tradeoff for 4x improvement in production mode.
```
Benchmark.ips do |r|
ActionMailer::Base.logger.level = ::Logger::Severity::DEBUG
r.report('no guard') { subscriber.process(event) }
r.report(' guard') { subscriber.process_with_guard(event) }
end
__END__
Calculating -------------------------------------
no guard 4970 i/100ms
guard 4564 i/100ms
-------------------------------------------------
no guard 55617.4 (±3.5%) i/s - 278320 in 5.010523s
guard 49452.1 (±5.6%) i/s - 251020 in 5.093358s

This was partially broken because `preview_interceptors=` just assigned the
raw values, whithout going through `register_preview_interceptor`. Now the
Action Mailer railtie takes care of the `preview_interceptors` option.
This commit is a partial revert of:

`ActionMailer::Base.delivery_method` and
`ActionMailer::Base.perform_deliveries` have leaked states.
"delivery method can be customized per instance" and "delivery method
can be customized in subclasses not changing the parent" in
delivery_methods_test.rb will fail if test_helper_test.rb (in which
TestHelperMailerTest is inherited from ActionMailer::TestCase) runs
before it.

This method return `Gem::Version.new(Rails.version)`, suggesting a more
reliable way to perform version comparison.
Example:
Rails.version #=> "4.1.2"
Rails.gem_version #=> #<Gem::Version "4.1.2">
Rails.version > "4.1.10" #=> false
Rails.gem_version > Gem::Version.new("4.1.10") #=> true
Gem::Requirement.new("~> 4.1.2") =~ Rails.gem_version #=> true
This was originally introduced as `.version` by @charliesome in #8501
but got reverted in #10002 since it was not backward compatible.
Also, updating template for `rake update_versions`.

We allow the use of underscored symbols to represent classes throughout
other parts of Rails so it seems incongruous that it's not supported in
`register_interceptor` and `register_observer`.

Since preview_path is read from ActionMailer::Base when previewing, subclasses
can’t change it so don’t there's no need for the extra overhead imposed by using it.

To support the ability for tools like CSS style inliners to operate on emails
being previewed this commit adds a hook in a similar fashion to the existing
delivery interceptor hook, e.g:
class CSSInlineStyler
def self.previewing_email(message)
# inline CSS styles
end
end
ActionMailer::Base.register_preview_interceptor CSSInlineStyler
Fixes #13622.

Only config.autoload_paths is frozen, so add the preview_path
to ActiveSupport::Dependencies.autoload_paths directly in an
after_initialize block. Also protect against a blank preview_path
being added to autoload_paths which can cause a serious slowdown
as Dir[] tries to load all *_preview.rb files under /

This behavior is documented in our guides (http://edgeguides.rubyonrails.org/action_mailer_basics.html#action-mailer-callbacks)
but was broken in the past. This commit short curcuits
the `mail` method if:
1. mail() was previously called
2. no headers are passed
3. no block is passed
Closes #13090.

The processing of outbound mail is instrumented with the key
`process.action_mailer`. The payload includes the mailer name as well as
the mailer method.
