Get rid of Netty's DelimiterBasedFrameDecoder

Netty's DelimiterBasedFrameDecoder is not really effective when dealing
with huge NETCONF messages and reading them in just really small parts
at a time.

DelimiterBasedFrameDecoder always searches whole input ByteBuf for
delimiter when new input bytes are available. It performs the search
also on bytes already checked in previous tries. Obviously, this can be
really ineffective when reading large messages by very small parts at
a time.

Replace Netty's DelimiterBasedFrameDecoder by our own frame detection
implementation. The implementation remembers already checked part of
the input ByteBuf and searches the delimiter just in a new bytes
available.

Eliminate BootstrapConnectListener

Use a simple method and a method handle instead of an explicit
class. This makes things a tad simpler on synchronization side of
things.

Centralize NetconfNode/InetSocketAddress conversion

The process of creating a RemoteDeviceId and/or the target
InetSocketAddress is duplicated in a number of places, each slightly
different.

Centralize conversion in netconf.topology.spi and use it from there,
which leads us to topology-singleton being able to use non-IP addresses.

Fix PATCH request issue with top-level container as target

PATCH request to the data root with a top-level container as
target does not work because JsonPatchBodyReader and
XmlPatchBodyReader expect a parent statement in the stack.

schema context when stack is empty and add test cases for
JsonPatchBodyReader and XmlPatchBodyReader.
