Fabricio Voznika 0b76887147 Priority-inheritance futex implementation
It is Implemented without the priority inheritance part given
that gVisor defers scheduling decisions to Go runtime and doesn't
have control over it.

Michael Pratt ddb34b3690 Enforce message size limits and avoid host calls with too many iovecs
Currently, in the face of FileMem fragmentation and a large sendmsg or
recvmsg call, host sockets may pass > 1024 iovecs to the host, which
will immediately cause the host to return EMSGSIZE.

When we detect this case, use a single intermediate buffer to pass to
the kernel, copying to/from the src/dst buffer.

To avoid creating unbounded intermediate buffers, enforce message size
checks and truncation w.r.t. the send buffer size. The same
functionality is added to netstack unix sockets for feature parity.
