check_bgp_neighbors

this works well for checking our bgp-speakers. it would be even nicer if the "-n" parameter could be ignored so only one command definition would be needed in case you have a different number of neighbors on some devices. Also we had to fix one line: last_output=`/bin/cat /tmp/check_bgp_all.$hostname|grep $neighbor` changed to: last_output=`/bin/cat /tmp/check_bgp_all.$hostname|grep $neighbor:` the ":" is needed to match only exact neighbor IPs, we for example hat x.y.c.2 and x.y.c.20 as neighbors to one bgp-speaker therefore the grep without ":" made for some bad responses which lead to expr-errors later in the script.
