Return statements in functions returning bool should use
true/false instead of 1/0.
These issues were detected with the help of Coccinelle.

Otherwise, user cannot add related rules if xt_ipcomp.ko is not loaded:
# iptables -A OUTPUT -p 108 -m ipcomp --ipcompspi 1
iptables: No chain/target/match by that name.

Fix this by using ntohs without shifting.
Tested with: make C=1 CF=-D__CHECK_ENDIAN__

With this plugin, user could specify IPComp tagged with certain
CPI that host not interested will be DROPped or any other action.
For example:
iptables -A INPUT -p 108 -m ipcomp --ipcompspi 0x87 -j DROP
ip6tables -A INPUT -p 108 -m ipcomp --ipcompspi 0x87 -j DROP
Then input IPComp packet with CPI equates 0x87 will not reach
upper layer anymore.
