Bhasker Hariharan 7e4073af12 Move tcpip.PacketBuffer and IPTables to stack package.
This is a precursor to be being able to build an intrusive list
of PacketBuffers for use in queuing disciplines being implemented.

Ian Gudger 27500d529f New sync package.
* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.

This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.

Kevin Krakauer 12235d533a AF_PACKET support for netstack (aka epsocket).
Like (AF_INET, SOCK_RAW) sockets, AF_PACKET sockets require CAP_NET_RAW. With
runsc, you'll need to pass `--net-raw=true` to enable them.

Binding isn't supported yet.

Kevin Krakauer 9b4d3280e1 Add IPPROTO_RAW, which allows raw sockets to write IP headers.
iptables also relies on IPPROTO_RAW in a way. It opens such a socket to
manipulate the kernel's tables, but it doesn't actually use any of the
functionality. Blegh.

Nicolas Lacasse bfd9f75ba4 Set the FilesytemType in MountSource from the Filesystem.
And stop storing the Filesystem in the MountSource.

This allows us to decouple the MountSource filesystem type from the name of the
filesystem.

Tamir Duberstein 0e1cc476db Fix transport/raw copybara export
- include packet_list.go
- exclude state.go (by renaming to include an underscore)

Also rename raw.go to endpoint.go for consistency.

Kevin Krakauer 52a51a8e20 Add a raw socket transport endpoint and use it for raw ICMP sockets.
Having raw socket code together will make it easier to add support for other raw
network protocols. Currently, only ICMP uses the raw endpoint. However, adding
support for other protocols such as UDP shouldn't be much more difficult than
adding a few switch cases.
