Allow writing an IPv6 packet where the IPv6 header is a provided by
the user.
* Introduce an error to let callers know a header is malformed.
We previously useed tcpip.ErrInvalidOptionValue but that did not seem
appropriate for generic malformed header errors.
* Populate network header in WriteHeaderIncludedPacket
IPv4's implementation of WriteHeaderIncludedPacket did not previously
populate the packet buffer's network header. This change fixes that.
Fixes #4527
Test: ip_test.TestWriteHeaderIncludedPacket

In case setting up network fails, log a warning and fallback to internal
network.

By exposing an ALL_TESTS list in defs.bzl we can make sure all packetimpact
users get to agree on the list of all tests. A defect in this approach is that
we have to keep a list of packetimpact_testbench rules in the BUILD file. An
helper validate_all_tests has been added to help keep BUILD and .bzl files in
sync.

RFC 4861 section 4.4 comments the Target link-layer address option is sometimes
optional in a Neighbor Advertisement packet:
"When responding to a unicast Neighbor Solicitation this option SHOULD be
included."
Tests:
pkg/tcpip/stack:stack_test
- TestEntryStaleToReachableWhenSolicitedConfirmationWithoutAddress
- TestEntryDelayToReachableWhenSolicitedConfirmationWithoutAddress
- TestEntryProbeToReachableWhenSolicitedConfirmationWithoutAddress
pkg/tcpip/network/ipv6:ipv6_test
- TestCallsToNeighborCache

Test helpers should be used for test setup/teardown, not actual
testing. Use cmp.Diff instead of bytes.Equal to improve readability.

This change also brings back the stack.Route.ResolveWith method so that
we can immediately resolve a route when sending an NA in response to a
a NS with a source link layer address option.

Control messages should be released on Read (which ignores the control message)
or zero-byte Send. Otherwise, open fds sent through the control messages will
be leaked.

All shm segments in an IPC namespace should be released once that namespace is
destroyed. Add reference counting to IPCNamespace so that once the last task
with a reference on it exits, we can trigger a destructor that will clean up
all shm segments that have not been explicitly freed by the application.

Remove the duplicate NA size variable while I'm here.
See https://tools.ietf.org/html/rfc4861#section-4.4 for the packet format.

The sentry page cache stores file contents at page granularity; this is
necessary for memory mappings. Thus file offset ranges passed to
fsutil.FileRangeSet.Fill() must be page-aligned. If the read callback passed to
Fill() returns (partial read, nil error) when reading up to EOF (which is the
case for p9.ClientFile.ReadAt() since 9P's Rread cannot convey both a partial
read and EOF), Fill() will re-invoke the read callback to try to read from EOF
to the end of the containing page, which is harmless but needlessly expensive.
Fix this by handling file size explicitly in fsutil.FileRangeSet.Fill().

Use the correct constant (Solicit, not Advert) while I'm here.

This fixes reference leaks related to accidentally forgetting to DecRef()
after calling one or the other.

The required states may simply not be observed by the thread running bounce, so
track guest and user generations to ensure that at least one of the desired
state transitions happens.

In addition to fixing reference leaks, this change also releases memory used
by regular tmpfs files once the containing filesystem is released.
