All inbound segments for connections in ESTABLISHED state are delivered to the
endpoint's queue but for every segment delivered we also queue the endpoint for
processing to a selected processor. This ensures that when there are a large
number of connections in ESTABLISHED state the inbound packets are all handled
by a small number of goroutines and significantly reduces the amount of work the
goscheduler has to perform.
We let connections in other states follow the current path where the
endpoint's goroutine directly handles the segments.

Added tests for tcp protocol with input and output rules including options sport and dport
Increased timeout in iptables_test as TCP tests were timing out with existing value.
This test fails on ubuntu 18.04 because preadv2 for some reason returns
EOPNOTSUPP instead of EINVAL. Instead of root-causing the failure, I'm dropping
the flag in the preadv2 call since it isn't under test in this scenario.

CancellableTimer tests were in a timer_test package but lived within the
tcpip directory. This caused issues with go tools.

* 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.

bm-tools works via "Machine" objects, which are front
objects for actual virtual or physical machines. glcoud_producer
produces machines on GCP using the `gcloud` tool.
Included are:
- GCloudProducer - the class producing machines
- MockGCloudProducer - class for mocking GCloudProducer.
- tests using the mock
- test data as .json files. Code to generate this test data may be
included in a follow up.

Inform the Stack's NDPDispatcher when it receives an NDP Router Advertisement
that updates the available configurations via DHCPv6. The Stack makes sure that
its NDPDispatcher isn't informed unless the avaiable configurations via DHCPv6
for a NIC is updated.
Tests: Test that a Stack's NDPDispatcher is informed when it receives an NDP
Router Advertisement that informs it of new configurations available via DHCPv6.

Internal tools timeout after 60s during tests that are required to pass before
changes can be submitted. Separate out NDP tests into its own package to help
prevent timeouts when testing.

Fix the indentation and print statements.
Moved the NAT redirect tests to new file.
Added negative test to check redirect rule on ports other than
redirected port.
...retrievable later via stack.NICInfo().
Clients of this library can use it to add metadata that should be tracked
alongside a NIC, to avoid having to keep a map[tcpip.NICID]metadata mirroring
stack.Stack's nic map.

When PCID is disabled, there would throw a panic
when dropPageTables() access to c.PCID without check.

Add a new CancellableTimer type to encapsulate the work of safely stopping
timers when it fires at the same time some "related work" is being handled. The
term "related work" is some work that needs to be done while having obtained
some common lock (L).
Example: Say we have an invalidation timer that may be extended or cancelled by
some event. Creating a normal timer and simply cancelling may not be sufficient
as the timer may have already fired when the event handler attemps to cancel it.
Even if the timer and event handler obtains L before doing work, once the event
handler releases L, the timer will eventually obtain L and do some unwanted
work.
To prevent the timer from doing unwanted work, it checks if it should early
return instead of doing the normal work after obtaining L. When stopping the
timer callers must have L locked so the timer can be safely informed that it
should early return.
Test: Tests that CancellableTimer fires and resets properly. Test to make sure
the timer fn is not called after being stopped within the lock L.

This change calls a new Truncate method on the EndpointReader in RecvMsg for
both netlink and unix sockets. This allows readers such as sockets to peek at
the length of data without actually reading it to a buffer.

For everyone's joy, this is a tool that reopens issues that
have been closed, but are still referenced by TODOs in the
code. The idea is to run it in Kokoro nightly. Kokoro changes
are coming up next.
