Fixes SI-4929, with a test to verify.

Also fixes potential issue with Parsers.phrase not being reentrant; however, I was unable to actually reproduce this issue in practice. (The order in which lastNoSuccess was being set and compared seemed to guarantee that it would never actually be a problem).
Space/Tab cleanup script - run before committing

Running this script will transform tabs into a pair of spaces and will
eliminate trailing spaces. Use at your own risk!
Ctor default-getters unique name and are typed in constructor context
Remove sbaz and references from master repository.
Rename ConcurrentTrieMap to concurrent.TrieMap.

Introduced the collection.concurrent package and introduced the
concurrent.Map trait there. Deprecated the mutable.ConcurrentMap trait.

Pending work - introduce the appropriate changes to JavaConversions
and JavaConverters.
Merge remote-tracking branch 'axel22/feature/collection-concurrent' into develop
Merge remote-tracking branch 'jsuereth/remove-sbaz-update-man' into develop
String interpolation bug fix

This change fixes a bug in class StringContext.scala.
Parts were not correctly added to the resulting string.

This commit includes a test case which covers the
example reported in the bug.

Closes SI-5614.
Add JavaConversions and JavaConverters concurrent.Map support.

This required deprecating several old methods for converting ConcurrentMap.
Also, several new wrappers were introduced for concurrent.Map. Once we
remove ConcurrentMap in 2.11, we can remove its corresponding wrappers and
conversions in JavaConversions and JavaConverters.
SIP-11 String Interpolation Simplification

Changed StringContext.f which implements the formatted
string interpolator.

Any '%' not in formatting position is left in the resulting string literally.
However, instead of adding %s format holders and extending the args with "%"
expressions, these '%' are replaced by '%%'. The formatter then converts '%%'
(percent formatter) to the literal '%' (\u0025). This also simplifies the spec.

The interpolation tests still pass.

Work on source compatibility between akka and scala futures.

Removed some methods from execution contexts.
Changed Awaitable interface.
Revived the lisp test.

All hail the lisp test!

Closes SI-4579.
Never write final fields outside of constructors.

Closes SI-3569, SI-3770.

Also threw in experimental -Yoverride-vars.  It's not robust.
Revert the lisp test.

The lisp test enjoys the suffering of others.
Add methods in the Future companion object.
Add withFilter and mapTo to futures.
Adds links to parallel collections overview in API docs

Now that there's an extensive parallel collections overview on http://docs.scala-lang.org, API comments should link to it ("see also" field). This commit also fixes a couple of broken links on some sequential collection types.
A couple tests for pending.
Cleaning up logging in specialization.
