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.
Updates #230
PiperOrigin-RevId: 253168283
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.

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.

Some behavior was broken due to the difficulty of running automated raw
socket tests.

- include packet_list.go
- exclude state.go (by renaming to include an underscore)
Also rename raw.go to endpoint.go for consistency.
