* Remove usage of HandlerList and reduce usage of Handler.Collection
"The best part is no part" - Elon Musk!
The overwhelming usage of `HandlerList` and `Handler.Collection` was for adding the `DefaultHandler` after the main handler. This PR adds a getter/setter for a `DefaultHandler` on the server, so we no longer need to always create a `Handler.Collection` structure. This has allowed the deprecated `HandlerList` and `HandlerWrapper` classes to be removed.
In implementing this PR, several problems were found in the calculation of `InvocationType`, not least that it was assumed that an empty `Handler.Collection` was `BLOCKING`. When this issue was fixed, any dynamic addition of contexts (deployer or SPI server) failed as the `InvocationType` changed. So this PR also introduces the `isDynamic()` attribute of all `Handler.Container`s. A dynamic container will always return `BLOCKING` from `getInvocationType()`, as there is always a race with a new handler being added. A non-dynamic container will return a real `InvocationType`, calculated from its children, but it's mutator methods will ISE if contained handlers are changed.

* Reorganization of jetty-client classes.
* Moved oej.client.api to oej.client
* Moved oej.client.util to oej.client
* Moved implementation classes to oej.client.internal
* Moved transports to oej.client.transport
* Moved transport implementation classes to oej.client.transport.internal
* Moved TunnelRequest to oej.client.internal.
* Moved FastCGI transport classes to o.e.j.fcgi.transport
* Moved FastCGI transport implementation classes to o.e.j.fcgi.transport.internal
* Updated WebSocket core client to use only exported, non-internal, oej.client classes.
* Expanded oej.client.Destination APIs:
- added: getOrigin(), isSecure(), getProxy(), getConnectionPool(), getHttpClient(), send(..).
- removed: getScheme(), getHost(), getPort() because they don't uniquely identify a Destination anymore (Origin does)
* Moved destination sweeper functionality from HttpDestination to HttpClient.
HttpDestination does not implement close() anymore, now relies on LifeCycle.stop()
* Moved HttpReceiver.storeCookie() logic to HttpClient.putCookie() to avoid exposing CookieManager.
* Moved HttpClient.getAcceptEncodingField() to ContentDecoder.Factories
* Avoid public/protected Logger instances.

Alternative Handler architecture.
All Handlers are Processors, which now return a boolean to indicate the request has been accepted.
The request/response/callback are no longer modal, so there is no race with the boolean return.
Optimized PathMappings.
Avoid iterations if only ServletPathSpec instances
Avoid tests for empty mappings.
Better reset implementation
Improve suffix matching
Improve exact matching
Renamed HttpStream.getNanoTimeStamp() to getNanoTime().

Introduced a new io.Content class, with Content.Source, Content.Sink and Content.Chunk.
Updated the server-side to use io.Content instead of the previous server-side Content class.
Updated the client-side to use io.Content with a little specialization necessary for clients only.
