[plt-scheme] SRFI-1 move to scheme/list?

Hello,

Now that many list functions are moving into the core of PLT Scheme
(scheme, scheme/base, etc.) should all of the SRFI-1 functions move to
scheme/list?   Using SRFI-1 is now a bit of a pain due to name
collisions.  We could change SRFI-1 to avoid name collisions
(extending what is already done) but it seems the intention is that
scheme/list will provide all the common functions.
