Add logging of various operations the transactional class file manager is
doing. You can pass logger to be used by the transactional class file
manager by using overloaded definition of `ClassfileManager.transactional`
method. The old overload has been deprecated.
The factory methods for class file manager in IncOptions companion object
has been deprecated in favor of using ClassfileManager companion object
directly. The code in Defaults.scala has been updated to use non-deprecated
methods. The logging is turned off by default.
The canonical way of enabling transactional class file manager in sbt
project is:
```
incOptions := incOptions.value.withNewClassfileManager(
sbt.inc.ClassfileManager.transactional(
crossTarget.value / "classes.bak",
(streams in (compile, Compile)).value.log
)
)
```
It's a bit verbose which shows that the api for this is not the best.
However, I don't expect sbt users to need this code very often.
This patch should help debug the problem described in #1184
It should have been there from the beginning because NameHashing is tied
to internals of the API subproject.
It was added to incremental subproject by mistake.
The deprecated method should forward to the other overloaded alternative
but it recursed instead.
This kind of mistake would be easily caught by linter warning about
unused `newConfig` local variable. I hope we'll get there some day.
Fixes#1251
`DefaultOptions.addResolvers` and `DefaultOptions.addPluginResolvers`
should not reset the existing value while adding the new ones. The
names are prefixed with _add_ afterall.

1) When `test` is run and there are no tests available, omit logging output.
Especially useful for aggregate modules. `test-only` et al unaffected. (#1185)
2) Added a new setting `testResultLogger` to allow customisation of logging of test results.
* Expose new EvaluateTaskConfig throughout all the APIs
* Create a key for cancellation configuration
* Add default values for cancellation in GlobalPlugin
* Create a test to ensure that cancellation can cancel tasks.
* Deprecate all the existing mechanisms of evaluating tasks which
use the EvaluateConfig API.
* Create a new EvaluateTaskConfig which gives us a bit more freedom
over changign config options to EvaluateTask in the future.
* Create adapted from old EvaluateTask to new EvaluateTask
* Add hooks into signals class to register/remote a signal listener
directly, rather than in an "arm" block.
* Create TaskEvaluationCancelHandler to control the strategy of
who/whom can cancel (sbt-server vs. sbt-terminal).
* Create a null-object for the "can't cancel" scenario so the
code path is exactly the same.
This commit does not wire settings into the build yet, nor does it
fix the config extractio methods.
