New encoding (local RPC), also reflected in the pktdump utility
prepared for adding "local rpc" support
added test packets for CCNx' and NDN's new formats
encoding and decoding of the RPC Date Representation data structure.
typo in the #define for TLV_INT macro
rearranged code pieces for utility procedures (hex2int, unescape_component)
Weiterer Support für NDN's neues Packetformat (vorerst ccn-lite-relay.c)
prefixed all CCNB related routines with ccnl_ccnb_*; ccn-lite-peek.c now drops link/face related interests and waits for content/data datagrams only
ccn-lite-peek.c now drops non-content packets for CCNB encoding too, not only NDNTLV
moved the enum for CCNL_SUITE_* to ccnl.h; moved ccnl_pkt2suite() to ccnl-util.c
refactored ccn-lite-peek.c
