Because symtab.c was partially converted before,
the diffs are not terribly useful.
The earlier conversion was trying to refactor or
clean up the code in addition to doing the translation.
It also made a mistake by redefining Func to be something
users could overwrite.
I undid those changes, making symtab.go a more
literal line-for-line translation of symtab.c instead.

uintptr or uint64 in the runtime C were turning into uint in the Go,
bool was turning into uint8, and so on. Fix that.
Also delete Go wrappers for C functions.
The C functions can be called directly now
(but still eventually need to be converted to Go).

Now 'go vet runtime' only shows:
malloc.go:200: possible misuse of unsafe.Pointer
malloc.go:214: possible misuse of unsafe.Pointer
malloc.go:250: possible misuse of unsafe.Pointer
stubs.go:167: possible misuse of unsafe.Pointer
Those are all unavoidable.

This change introduces gomallocgc, a Go clone of mallocgc.
Only a few uses have been moved over, so there are still
lots of uses from C. Many of these C uses will be moved
over to Go (e.g. in slice.goc), but probably not all.
What should remain of C's mallocgc is an open question.

Also implement go:nosplit annotation. Not really needed
for now, but we'll definitely need it for other conversions.
