Summary: check_tcp fails to detecd some problems

Initial Comment:
check_tcp uses same buffer for sending and receiving for 
send/expect strings. if remote service closes the
connection without
any data, check_tcp uses the same buffer for
comparison, and 
if you expect to have same string, it fails to detect
the problem.

The small patch below works for me. It also ensures
that NULL string
is not passed to strip() (so strlen()) which core dumps
on my 
(debian 3.0 with linux kernel 2.4.19, glibc 2.2.5) box
at least. This
is against nagiosplug-1.3-beta1.
