Brian Geffon 0212f222c7 Fix refcount bug in rpcinet socketOperations.Accept.

Brian Geffon 7f62e9c32e rpcinet connect doesn't handle all errnos correctly.
These were causing non-blocking related errnos to be returned to
the sentry when they were created as blocking FDs internally.

Kevin Krakauer 705605f901 sentry: Add simple SIOCGIFFLAGS support (IFF_RUNNING and IFF_PROMIS).
Establishes a way of communicating interface flags between netstack and
epsocket. More flags can be added over time.

Kevin Krakauer d4c81b7a21 sentry: Get "ip link" working.
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.

Christopher Koch d154c6a25f Refcount socket Dirents correctly.
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.

Kevin Krakauer 96c28a4368 sentry: Replaces saving of inet.Stack with retrieval via context.
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to use the old stack, which will have been replaced by a new stack on the new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.
