Added a heuristic to the inliner.

But it's commented out because I want to get this logging
code into 2.10 without including anything "interesting".
Worked around SI-6161 by annotating abstract type.
Took measures to quiet down specialization logging.

While hopefully still hearing about certain things (like symbol renames)
when it's not a specialized symbol.
Large logging cleanup effort.

Quieted down many logging statements which contribute
disproportionate noise.  Made others emit something more sensible.
Spent lots of time on the inliner trying to find a regular
format to make the logs more readable.  Long way to go here but
it'd be so worth it to have readable logs instead of mind-numbing
indiscriminate text dumps.
several fixes to scala.concurrent.util.Duration

- add test cases (migrated from Akka sources)
- add overflow checking (will throw IllegalArgumentException instead of
  giving wrong results)
- make string parsing more precise when giving >100days in nanoseconds
- make method signatures more precise in retaining FiniteDuration
  throughout calculations
- fix mul/div of infinities by negative number
- add Ordering for Deadline (was accidentally left out earlier)
Fixes SI-6271 - Missing isEmpty override for views.

GenIterableView didn't override isEmpty for views to look at *filtered* iterator, but was instead pulling
unfiltered iterator and causing issues.   Chalk up another bizzare bug to lack of insight/visibility into
linearization and what havoc overriding new methods can spew on our library.
second round of Duration cleanup

- make Duration behave consistent with Double's non-finite semantics
- add ScalaDoc
- add complete test suite
- change overflow protection impl after review comments
- clean up code
fix some one more issue in Duration

- Inf / Zero == Inf
- add some more missing test cases
- clarify magic constant
- move exception descriptions into proper @throws docs
fix two minor issues in Duration

- make constants for fromNanos(Long) actually inlined constants
- clarify origin of require() check constants in FiniteDuration
SI-6335 More precise location of the implicit class synthetic method.

One approach would be to disallow an implicit class in a template
that already has a member with the same name.

But this commit doesn't do this; instead it uses `isSynthetic` to
find the synthesized implicit conversion method from the potentially
overloaded alternatives.
More tests for SI-6335.
fix usage of Duration in Promise impl

- correctly treat MinusInf and Undefined
- don't toMillis in the timeout message (could be MinusInf)
- also notice that Inf did not actually wait unbounded
- and further notice that tryAwait swallows InterruptedException instead
  of bailing out early => changed to do so and added throws annotation
- also removed some unused imports of Duration
Fix t6114 - ++ on JList wrapper modifies underlying collection.

We solve this by overriding clone for JListWrapper to actually do a full clone.

Note: This fix may need to be included other places, *but* we're not sure we've cloned the collection sensibly.  I.e.  is ArrayList a good default?

improve docs and Promise impl

- scaladoc the exceptions thrown by Await.* and Awaitable.*
- move intercept[Exception] into partest’s TestUtil object
- improve Promise.tryAwait implementation following Viktor’s comments
  and make use of Deadline to avoid calling System.nanoTime too often
