change representation of interface values.
...
this is not a user-visible change.
before, all interface values were
struct Itype {
Sigt *type;
Sigi *inter;
void *method[n];
}
struct Iface {
void *addr;
Itype *itype;
}
the itype is basically a vtable, but it's unnecessary
if the static type is interface{ }.
for interface values with static type empty, the
new representation is
struct Eface {
void *addr;
Sigt *type;
}
this complicates the code somewhat, but
it reduces the number of Itypes that
have to be computed and cached,
it opens up opportunities to avoid function
calls in a few common cases,
and it will make it possible to lay out
interface{} values at compile time,
which i think i'll need for the new reflection.

this avoids problems people have run into with
multiple closures in the same package.
when preparing filename, only cut off .go, not .anything.
this fixes a bug tgs ran into with foo.pb.go and foo.go
in the same package.
also turn bad identifier chars from filename into
underscores: a-b.pb.go => a_b_pb

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.
