yaffs: fix getxattr support

When passed a buffer size of 0, getxattr(2) is documented to return the
size of the attribute value.  However, yaffs returns -ERANGE instead.
This breaks SELinux usage of getxattr.  Fix yaffs to return the
attribute size in this case.

yaffs: set security attribute at file creation

Add support to yaffs to set the security attribute of new inodes when
they are created.  This parallels similar support in other filesystems,
and is a requirement for SELinux and other MAC systems.

Do not ratelimit audit messages. We want to see them all.

Fix security_binder_transfer_binder hook.

Drop the owning task argument to security_binder_transfer_binder
since ref->node->proc can be NULL (dead owner?).
Revise the SELinux checking to apply a single transfer check between
the source and destination tasks.  Owning task is no longer relevant.
Drop the receive permission definition as it is no longer used.

This makes the transfer permission similar to the call permission; it is only
useful if you want to allow a binder IPC between two tasks (call permission)
but deny passing of binder references between them (transfer permission).
