build: Changing the way version is managed

Now control over the version number is moved to wscript.  In addition to
that, a new NDN_CXX_VERSION_BUILD_STRING macro is set to include more
detailed information, including commit ID (e.g., "0.1.0-rc1-1-g5c86570").

face: Implementing InterestFilter abstraction to be used with setInterestFilter

This commit minimally changes the API, primarily altering the internal
structures preparing for separation of `registerPrefix` (=send a command
to local forwarder to register FIB/RIB entry) and `setInterestFilter`
(=update library's InterestFilter->Callback dispatch table).

The existing setInterestFilter methods preserve all previous functionality
(any string URI or ndn::Name can be supplied as a first parameter),
but also allow InterestFilter as the filtering parameter.
InterestFilter, provides a way to select Interest either based on prefix,
as before, or based on prefix and regular expression.

face+management: Removing ndnd::Controller and re-designing controllers

As of this commit, there is only one controller: nfd::Controller.
Legacy ndnd-tlv is no longer supported, but it is still possible to use
NFD FIB Management directly (RIB Management commands are used by
default).  To request direct FIB management, one needs to call
Face::setDirectFibManagement(true) or configure protocol variable in the
config file.

Instead of using virtual methods of the controllers, a special
setInterestFilterImpl method will select proper prefix registration
method.  In addition to that, setInterestFilterImpl will also remember
how exactly the prefix should be de-registered, including security
parameters.

face: Finalizing separation between registerPrefix and setInterstFilter

New registerPrefix and setInterestFilter methods allow distinct
operations of registering with local NDN forwarder (e.g., using RIB
management protocol) and setting up application-specific OnInterest call
dispatch using InterestFilters.
