Make demo script running again
Update ndn script to work with new peek.
Merge branch 'ccntlv' of github.com:cn-uofbasel/ccn-lite into ccntlv
removed a variable causing compiler warnings (depending on enables USE_XX modules)
Example of adding a builtin function, in this case "getFromNameSpace" (name space translation, see ccnl-ext-nstrans.c)
forgot to add the new file ccnl-ext-nstrans.c
lets ccn-lite-pktdump return only the object's content (optionally with a trailing \n)
first version of util/ccn-lite-simplenfn.c
had to finish the job of cccn-lite-pktdump.c returning the content only, for the two other packet suites
factored out all includes of the utility programs, now concentrated in util/cncl-common.c
refactored strdup() (now it's ccnl_strdup), this shaved 100 lines from ccnl-ext-nvnkrivine.c
merged ccntlv
added ccnl-common.c lib to produce/fetch
