Some users might want to prefer one babel implementation over another
for various reasons. Having to compile the firmware from scratch can be
quite tedious in that case.
Instead, make the babel implementation switchable at runtime.
Currently, the implementation has to be switched manually in
/lib/functions/fff/babel, which is not upgrade-safe. Also, the previous
implementation is currently not restored after test-mode, so switching
implementations should not be done with test-mode.

To be able to swap out babeld for a different babel implementation in
the future, this splits all fff-specific configuration into a seperate
fff-babel package.
Implementation specific configuration is done in
/lib/functions/fff/babeldaemon, which is included with every selectable
babel implementation. It contains functions, which are called by the
fff-specific code, and therefore allows to configure the implementation
specific parts.
The babel implementation is provided by implementation-specific
fff-packages, which provide 'fff-babel-implementation'. At the moment,
only fff-babeld is supported for use as babel implementation.

PKG_BUILD_DIR has the following default values set in include/package.mk,
in case no BUILD_VARIANT is set:
With PKG_VERSION set: $(BUILD_DIR)/$(PKG_NAME)-$(PKG_VERSION)
Without PKG_VERSION: $(BUILD_DIR)/$(PKG_NAME)
Consequently, all PKG_BUILD_DIR definitions in our packages are
redundant. Remove them.

The cake scheduler is a popular fair queuing scheduler, which is also
capable of shaping traffic. Due to its sensible defaults it is very
easy to set up.
When tunnel traffic exceeds the capability of the transport connection,
firmware users might want to shape traffic, so meaningful queueing can be done
before tunnel packets are dropped. As this is typically combined with a fair
scheduler, cake provides a simple yet very powerful solution for both problems.
Therefore the cake kernel module is now included in the layer3 variant.

Build/Prepare and Build/Configure are not required for packages
which only contain local files and do not need any compilation.
Remove them.
Note that Build/Compile needs to be present and empty to overwrite
the defaults, though.

The term "gateway" is ambiguous, and we are using "layer 3" for this
flavor now. Reflect that in the package name as well.
This is cosmetic otherwise.
