Subject: Move list types from <linux/list.h> to <linux/types.h>.

This allows a list_head (or hlist_head, etc.) to be used from places
that used to be impractical, in particular <asm/processor.h>, which
used to cause include file recursion: <linux/list.h> includes
<linux/prefetch.h>, which always includes <asm/processor.h> for the
prefetch macros, as well as <asm/system.h>, which often includes
<asm/processor.h> directly or indirectly.

This avoids a lot of painful workaround hackery on the tile
architecture, where we use a list_head in the thread_struct to chain
together tasks that are activated on a particular hardwall.

Subject: fix #warning about using kernel headers in userpsace

Move the preprocessor #warning message:
warning: #warning Attempt to use kernel headers from user space,
see http://kernelnewbies.org/KernelHeaders
from kernel.h to types.h.

And also fixe the #warning message due to the preprocessor not being able to
read the web address due to it thinking it was the start of a comment.  also
remove the extra #ifndef _KERNEL_ since it's already there.
