This is necessary since ptraceClone() mutates tracer.ptraceTracees.

Highlighting previously highlighted multiple items in the sidebar if the had
the same page name (not full url). This change simplifies this by adding the
highlight class in the jekyll template rather than javascript, and highlights
only the correct page.

On Linux these are meant to be equivalent to POLLIN/POLLOUT. Rather
than hack these on in sys_poll etc it felt cleaner to just cleanup
the call sites to notify for both events. This is what linux does
as well.

This change sets the inner `routeInfo` struct to be a named private member
and replaces direct access with access through getters. Note that direct
access to the fields of `routeInfo` is still possible through the `RouteInfo`
struct.

--file-access-mounts flag is similar to --file-access, but controls
non-root mounts that were previously mounted in shared mode only.
This gives more flexibility to control how mounts are shared within
a container.

Also adds support for clearing the setuid bit when appropriate (writing,
truncating, changing size, changing UID, or changing GID).
VFS2 only.

Stateify methods are always called without holding the appropriate
locks. The system is paused and we know there will be no mutations
when we call Save/Load, so this is perfectly safe. However, checklocks
can't know about this, and it will always complain.
Mark stateify generated methods that touch struct fields as
"checklocksignore" to avoid this.

The fio benchmark was changed to a fixed size read/write ammount
because the timed benchmark was overwhelming machine memory on
tmpfs mounts.
Now rand(read|write) operations are prohibitively long, leading to timeouts.
Split the benchmarks as they were in python bm-tools: the read/write as
fixed sized (1GB) and the rand(read|write) as timed operations (15s).

...instead of opting out of them.
Loopback traffic should be stack-local but gVisor has some clients
that depend on the ability to receive loopback traffic that originated
from outside of the stack. Because of this, we guard this change behind
IP protocol options.
A previous change provided the facility to deny these martian loopback
packets but this change requires client to opt-in to accepting martian
loopback packets as accepting martian loopback packets are not meant
to be accepted, as per RFC 1122 section 3.2.1.3.g:
(g) { 127, <any> }
Internal host loopback address. Addresses of this form
MUST NOT appear outside a host.

We were only supporting dynamic struct types. With this change, users can make
any type dynamic. The tool (correctly) blindly just generates the remaining
methods needed to implement Marshallable using the 3 methods defined by the
user on the dynamic type.
This is helpful in situations like:
type StringArray []string
Added a test for such a use case.

- Don't cleanup containers in Network.Cleanup, otherwise containers will
be killed and removed several times.
- Don't set AutoRemove for containers. This will prevent the confusing
'removal already in progress' messages.

This may be useful for tracking down where build tags come from and
understanding tag import issues in generated files.

The tests were not using the correct windowSize so the testing segments were
actually within the window for seqNumOffset=0 tests. The issue is already fixed
by #5674.

syserror allows packages to register translators for errors. These
translators should be called prior to checking if the error is valid,
otherwise it may not account for possible errors that can be returned
from different packages, e.g. safecopy.BusError => syserror.EFAULT.
Second attempt, it passes tests now :-)

Also, drop fio total reads/writes to 1GB as 10GB is
prohibitively slow.
