	sys/arch/i386/conf/ALL: revision 1.98
Revert a small part of revision 1.254 - remove const qualifier from
the struct tcphdr * argument of tcp_dooptions().  RFC2385 support
(options TCP_SIGNATURE) needs to modify the header during options
processing, and this revision broke it.
OK yamt@.

Fix compilation in the TCP_SIGNATURE case:
	- don't use void * for pointer arithmetic
	- don't try to modify const parameters
A kernel with 'options TCP_SIGNATURE' works as well as it ever did, now.
(ie, clunky, but passable)

Add 'options TCP_SIGNATURE' to hopefully keep this code from
invisibly breaking periodically, as it's done a couple times.
