Error returns for linux/arm syscalls are handled since a long time.
Remove another list of unimplemented syscalls, following CL 96315.
The root-only check in TestSyscallNoError was shown to be sufficient as
part of CL 84485 already.
NetBSD and OpenBSD do not implement the sendfile syscall (yet), so add a
link to golang.org/issue/5847

Add the rawSyscallNoError wrapper function which is used for Linux
syscalls that don't return an error and convert all applicable
occurences of RawSyscall to use it instead.

If there is a leading ·, assume there is a Go prototype and
attach the Go prototype information to the function.
If the function is not called from Go and does not need a
Go prototype, it can be made file-local instead (using name<>(SB)).
This fixes the current BSD build failures, by giving functions like
sync/atomic.StoreUint32 argument stack map information.
Fixes#8753.

Before, Syscall and friends were having their arguments
treated conservatively. Now they will use the Go prototype,
which will mean the arguments are not considered pointers
at all.
This is safe because of CL 139360044.
The fact that all these non-Solaris systems were using
conservative scanning of the Syscall arguments is why
the failure that prompted CL 139360044 was only
observed on Solaris, which does something completely different.
If we'd done this earlier, we'd have seen the Solaris
failure in more places.
