Find (and eliminate co-requisites) "q <- p" relation in dependency loop.

Search all successors of q for instance of p. Format the specific relation, (e.g. p contains "Requires: q"). Unlink and free co-requisite (i.e. pure Requires: dependencies) successor node(s).

Parameters:
qsucessor (i.e. package required by p)
ppredecessor (i.e. package that "Requires: q")
zapmax. no. of co-requisites to remove (-1 is all)?
Return values:
nzapsaddress of no. of relations removed
Parameters:
msglvlmessage level at which to spew
Returns:
(possibly NULL) formatted "q <- p" releation (malloc'ed)
