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.
