Add frienddestroy() and refactor removefriend()

friendcreate() populates the fs, frienddestroy() removes the
friend related files from the fs.

removefriend() only acts on the data from the friend's remove
fifo.  The "callback" in this case is responsible for reading the
fifo like in all other cases (sendfriendtext() etc.).

No weird dance with special function arguments to flag "official"
removal.  All friend related "callbacks" just need to operate on
a struct friend *.
