CLICON_CONFIGDIR with external subsystems causes endless looping

[pprindeville]

In the XML parsing in parse_configfile_one() we have the following loop.

The problem with the loop is that you can't "ignore" the nodes by just doing a continue. They need to be deleted from xe so that the next call to examine the head of the vector:

while ((xec = xml_child_i_type(xe, 0, CX_ELMNT)) != NULL) {

doesn't find them still there. We need to do a xml_child_rm() to remove them from xe before continuing the loop.
