MSG_TRUNC can cause recvmsg(2) to return a value larger than
the buffer size. In this situation it's an indication that the
buffer was completely filled and that the msg was truncated.
Previously in rpcinet we were returning the buffer size but we
should actually be returning the payload length as returned by
the syscall.

This change will add support for ioctls that have previously
been supported by netstack.

This change will add support for /proc/sys/net and /proc/net which will
be managed and owned by rpcinet. This will allow these inodes to be forward
as rpcs.

These were causing non-blocking related errnos to be returned to
the sentry when they were created as blocking FDs internally.

Establishes a way of communicating interface flags between netstack and
epsocket. More flags can be added over time.

In Linux, many UDS ioctls are passed through to the NIC driver. We do the same
here, passing ioctl calls to Unix sockets through to epsocket.
In Linux you can see this path at net/socket.c:sock_ioctl, which calls
sock_do_ioctl, which calls net/core/dev_ioctl.c:dev_ioctl.
SIOCGIFNAME is also added.

This should fix the socket Dirent memory leak.
fs.NewFile takes a new reference. It should hold the *only* reference.
DecRef that socket Dirent.
Before the globalDirentMap was introduced, a mis-refcounted Dirent
would be garbage collected when all references to it were gone. For
socket Dirents, this meant that they would be garbage collected when
the associated fs.Files disappeared.
After the globalDirentMap, Dirents *must* be reference-counted
correctly to be garbage collected, as Dirents remove themselves
from the global map when their refcount goes to -1 (see Dirent.destroy).
That removes the last pointer to that Dirent.

Previously, inet.Stack was referenced in 2 structs in sentry/socket that can be
saved/restored. If an app is saved and restored on another machine, it may try
to use the old stack, which will have been replaced by a new stack on the new
machine.
