16a85e6cca [#2307] Remove synchronized bottleneck in SingleThreadEventExecutor.execute(...)
Motivation:
Remove the synchronization bottleneck in startThread() which is called by each execute(..) call from outside the EventLoop.

Modifications:
Replace the synchronized block with the use of AtomicInteger and compareAndSet loops.

Result:
Less conditions during SingleThreadEventExecutor.execute(...)

e57cf9d201 Add capacity limit to Recycler / Optimize when assertion is off
Motivation:

- As reported recently [1], Recycler's thread-local object pool has unbounded capacity which is a potential problem.
- It accesses a hash table on each push and pop for debugging purposes.  We don't really need it besides debugging Netty itself.

Modifications:

- Introduced the maxCapacity constructor parameter to Recycler.  The default default maxCapacity is retrieved from the system property whose default is 256K, which should be plenty for most cases.
- Recycler.Stack.map is now created and accessed only when assertion is enabled for Recycler.

Result:

- Recycler does not grow infinitely anymore.
- If assertion is disabled, Recycler should be much faster.

1f5b74762b Correct ConcurrentHashMapV8 bitwise arithmetic
Previously ConcurrentHashMapV8 evaulated ((x | 1) == 0), an expression
that always returned false.  This commit brings Netty closer to the
Java 8 implementation.

9330172f80 Introduce a native transport for linux using epoll ET
This transport use JNI (C) to directly make use of epoll in Edge-Triggered mode for maximal performance on Linux. Beside this it also support using TCP_CORK and produce less GC then the NIO transport using JDK NIO.
It only builds on linux and skip the build if linux is not used. The transport produce a jar which contains all needed .so files for 32bit and 64 bit. The user only need to include the jar as dependency as usually
to make use of it and use the correct classes.

This includes also some cleanup of @trustin

b533a1361b Replace UniqueName with Constant and ConstantPool
- Proposed fix for #1824

UniqueName and its subtypes do not allow getting the previously registered instance.  For example, let's assume that a user is running his/her application in an OSGi container with Netty bundles and his server bundle.  Whenever the server bundle is reloaded, the server will try to create a new AttributeKey instance with the same name.  However, Netty bundles were not reloaded at all, so AttributeKey will complain that the name is taken already (by the previously loaded bundle.)

To fix this problem:

- Replaced UniqueName with Constant, AbstractConstant, and ConstantPool.  Better name and better design.

- Sctp/Udt/RxtxChannelOption is not a ChannelOption anymore.  They are just constant providers and ChannelOption is final now.  It's because caching anything that's from outside of netty-transport will lead to ClassCastException on reload, because ChannelOption's constant pool will keep all option objects for reuse.

- Signal implements Constant because we can't ensure its uniqueness anymore by relying on the exception raised by UniqueName's constructor.

309ee68c21 Fix a race condition in DefaultPromise
.. which occurs when a user adds a listener from different threads after the promise is done and the notifications for the listeners, that were added before the promise is done, is in progress.  For instance:

   Thread-1: p.addListener(listenerA);
   Thread-1: p.setSuccess(null);
   Thread-2: p.addListener(listenerB);
   Thread-2: p.executor.execute(taskNotifyListenerB);
   Thread-1: p.executor.execute(taskNotifyListenerA);

taskNotifyListenerB should not really notify listenerB until taskNotifyListenerA is finished.

To fix this issue:

- Change the semantic of (listeners == null) to determine if the early
  listeners [1] were notified
- If a late listener is added before the early listeners are notified,
  the notification of the late listener is deferred until the early
  listeners are notified (i.e. until listeners == null)
- The late listeners with deferred notifications are stored in a lazily
  instantiated queue to preserve ordering, and then are notified once
  the early listeners are notified.

[1] the listeners that were added before the promise is done
[2] the listeners that were added after the promise is done
