Noriko Hosoi 9ac54f0d7d Introducing an option preservecase to imudp and imtcp module for
managing the case of FROMHOST value.

Usage:
module(load="imudp" [preservecase="on"|"off"])
module(load="imtdp" [preservecase="on"|"off"])

If preservecase="on", FROMHOST value is handled in the case sensitive manner.
If preservecase="off", FROMHOST value is handled in the case insensitive manner.

To maintain the current behaviour, the default value of preservecase is
"on" for imtcp and "off" for imudp.

Incremented tcpsrvCURR_IF_VERSION by 1.
