Now if a process sends an unsupported netlink requests,
an error is returned from the send system call.
The linux kernel works differently in this case. It returns errors in the
nlmsgerr netlink message.

This change just introduces different congestion control states and
ensures the sender.state is updated to reflect the current state
of the connection.
It is not used for any decisions yet but this is required before
algorithms like Eiffel/PRR can be implemented.
Fixes #394

Previously we were representing socket addresses as an interface{},
which allowed any type which could be binary.Marshal()ed to be used as
a socket address. This is fine when the address is passed to userspace
via the linux ABI, but is problematic when used from within the sentry
such as by networking procfs files.

Endpoint protocol goroutines were previously started as part of
loading the endpoint. This is potentially too soon, as resources used
by these goroutine may not have been loaded. Protocol goroutines may
perform meaningful work as soon as they're started (ex: incoming
connect) which can cause them to indirectly access resources that
haven't been loaded yet.
This CL defers resuming all protocol goroutines until the end of
restore.

- Unexport Filesystem/Dentry/Inode.
- Support SEEK_CUR in directoryFD.Seek().
- Hold Filesystem.mu before touching directoryFD.off in
directoryFD.Seek().
- Remove deleted Dentries from their parent directory.childLists.
- Remove invalid FIXMEs.

- This also gets rid of pipes for now because pipe does not have vfs2 specific
support yet.
- Added file path resolution logic.
- Fixes testing infrastructure.
- Does not include unit tests yet.

This can happen because endpoint.Close() closes the accept channel first and
then drains/resets any accepted but not delivered connections. But there can be
connections that are connected but not delivered to the channel as the channel
was full. But closing the channel can cause these writes to fail with a write to
a closed channel.
The correct solution is to abort any connections in SYN-RCVD state and
drain/abort all completed connections before closing the accept channel.

If there is an offset, the file must support pread/pwrite. See

syscall.EPOLLET has been defined with different values on amd64 and
arm64(-0x80000000 on amd64, and 0x80000000 on arm64), while unix.EPOLLET
has been unified this value to 0x80000000(golang/go#5328). ref #63

(Don't worry, this is mostly tests.)
Implemented the following ioctls:
- TIOCSCTTY - set controlling TTY
- TIOCNOTTY - remove controlling tty, maybe signal some other processes
- TIOCGPGRP - get foreground process group. Also enables tcgetpgrp().
- TIOCSPGRP - set foreground process group. Also enabled tcsetpgrp().
Next steps are to actually turn terminal-generated control characters (e.g. C^c)
into signals to the proper process groups, and to send SIGTTOU and SIGTTIN when
appropriate.

We can get the mount namespace from the CreateProcessArgs in all cases where we
need it. This also gets rid of kernel.Destroy method, since the only thing it
was doing was DecRefing the mounts.
Removing the need to call kernel.SetRootMountNamespace also allowed for some
more simplifications in the container fs setup code.
