4eb7ceba58 complain when trying to put T into an interface 
if T has pointer methods.  this is just a heuristic
but it catches the problem robert ran into and
lets me put the larger interface issues aside for
now.  found one bug in pretty.

af678a593d new approach for generating sysimport.c 
(renamed to avoid any conflict with old p4 copies).

this approach doesn't require auto-generating
files also kept in p4, so it should be easier on
go users who don't sync very often.

this approach will be more work for go developers:
builtin.c needs to be copied to builtin.c.boot in p4
as new functions are added.  mkbuiltin does this
for certain $USERs to help us remember.
