Subject: [PATCH] -l (--log) flag

Hello,

This patch "adds back" the -l (--log) flag to iptables.
When this option is set for a rule, the kernel will print
the table name, chain name and rule number with some
information of all matching packets via printk at syslog
level debug. The option is for rule-debugging purposes
and not for regular logging - for the latter one should
use the LOG or ULOG target extensions!

This is a complete reworking of my 'trace' patch sent to the list:

- it does not depend any longer on the LOG target extension
- the restriction on the chain name length is removed, the
  max rulenum in a single chain which can generate a log message
  is bumped to 65535
- it logs the table name as well:

	tablename chainname/rulenum packet_dump
