Bhasker Hariharan 3d71c627fa Add support for TCP receive buffer auto tuning.
The implementation is similar to linux where we track the number of bytes
consumed by the application to grow the receive buffer of a given TCP endpoint.

This ensures that the advertised window grows at a reasonable rate to accomodate
for the sender's rate and prevents large amounts of data being held in stack
buffers if the application is not actively reading or not reading fast enough.

The original paper that was used to implement the linux receive buffer auto-
tuning is available @ https://public.lanl.gov/radiant/pubs/drs/lacsi2001.pdf

NOTE: Linux does not implement DRS as defined in that paper, it's just a good
reference to understand the solution space.

Rahat Mahmood 2d2831e354 Track and export socket state.
This is necessary for implementing network diagnostic interfaces like
/proc/net/{tcp,udp,unix} and sock_diag(7).

For pass-through endpoints such as hostinet, we obtain the socket
state from the backend. For netstack, we add explicit tracking of TCP
states.

Tamir Duberstein e4b395db49 Remove unused wakers
These wakers are uselessly allocated and passed around; nothing ever
listens for notifications on them. The code here appears to be
vestigial, so removing it and allowing a nil waker to be passed seems
appropriate.

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.

Kevin Krakauer ff8ed5e6a5 Fix raw socket behavior and tests.
Some behavior was broken due to the difficulty of running automated raw
socket tests.

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.
