[Syllable-kernel] DLIST -> tailqueue patch

[Daniel G. <da...@fp...>]

Hi, all.

I'm back from vacation, and have some time to work on Syllable.

Attached is a patch against current CVS to turn the DLIST into a tail
queue.  This allows DLIST_ADDTAIL() and DLIST_LAST() at the cost of a
pointer in the head (negligible), and the requirement of the head
pointer when removing or appending.
