RACK (Recent Acknowledgement) is a new loss detection
algorithm in TCP. These are the fields which should be
stored on connections to implement RACK algorithm.

This required minor fixes to the bazel wrapper. The "dut_platform" is
also changed to "native" to line-up with the system call tests and
remove the hard-coded "linux" and "netstack" strings.
The loader dup's stdio FD into stable FD's starting at a fixed
number. During tests, it's possible that the target FD is already
in use. Added check to error early so it's easier to debug failures.
Also bumped up the starting FD number to prevent collisions.

This will help manage memory consumption by IP reassembly when
receiving IP fragments on multiple network endpoints. Previously,
each endpoint would cap memory consumption at 4MB, but with this
change, each IP stack will cap memory consumption at 4MB.
No behaviour changes.

The utility has several differences from the VFS1 equivalent:
- There are no weak references, which have a significant overhead
- In order to print useful debug messages with the type of the reference-
counted object, we use a generic Refs object with the owner type as a
template parameter. In vfs1, this was accomplished by storing a type name
and caller stack directly in the ref count (as in vfs1), which increases the
struct size by 6x. (Note that the caller stack was needed because fs types
like Dirent were shared by all fs implementations; in vfs2, each impl has
its own data structures, so this is no longer necessary.)
As an example, the utility is added to tmpfs.inode.
Updates #1486.

The newer version of FUSE_INIT checks the response from the FUSE server
if its major number is equal to 7. If it's not, then FUSE_INIT fails and
further filesystem operations will get ECONNREFUSED. To mitigate this
issue, we can send back a response with major version equals to 7 when
consuming the first FUSE_INIT request.
Fixes#3500
This commit adds an integration test framework for FUSE support. Please
refer to the test example and test/fuse/README.md for further details.
Fixes#3098
- Exclude flaky tests.
- Bump timeout.
- Un-exclude passing tests to increase testing surface.
- Create/Update bugs for tests that pass on runc but fail on runsc.

Add three new doc pages to the website.
- A containerd quick start covering containerd 1.2. This is limited to shim v2
and runtime class as the docs would get too complicated explaining all the
combinations that are possible. We want folks to use shim v2 and runtime
class anyway.
- An advanced configuration page. This covers containerd and
containerd-shim-runsc-v1's configuration options.
- A page for old versions (i.e. containerd 1.1). Notes that this is deprecated
and supported on a best-effort basis.
Fixes#3279

Groups subcategories and sorts their pages by weight properly. Subcategories
are sorted by name. Pages within subcategories are sorted by weight.

This change adds a new reverse HTTP test where the HTTPD server runs
in a native container but the client runs inside gVisor. It allows
us to test download performance under varying levels of concurrency.
Also tweaks the concurrent request numbers to test for high levels
of concurrency.

The variable name is g which is collision with the reserved name
for R28. This leads to bazel build failure on ARM with following
information:
(register+register) not supported on this architecture
rename it from g to ptr (referenced from golang source
code)

Before kernel version 4.16-rc6, fuse mount is protected by
capable(CAP_SYS_ADMIN). After this version, it uses
ns_capable(CAP_SYS_ADMIN) to protect. Before the 4.16 kernel,
it was not allowed to mount fuse file systems without the
global CAP_SYS_ADMIN.
Fixes#3360
- Added a bunch of helpful options which help in speeding up the test and
providing useful output.
- Unexcluded passing tests and updated bugs. Excluded tests which were failing.
- Increased the batch size for java tests so that we can take advantage of
the shared JVMs.
The running time of the tests decreased from 3+ hours (I don't know the exact
running time because this test has always timed out after 3 hours) to 1 hour
15 minutes. We can reliably run this a CI kokoro job.

This change:
- Ports the nginx benchmark.
- Switches the Httpd benchmark to use 'hey' as a client.
- Moves all parsers to their own package 'tools'.
Parsers are moved to their own package because 1) parsing output of a command
is often dependent on the format of the command (e.g. 'fio --json'), 2) to
enable easier reuse, and 3) clean up and simplify actual running benchmarks
(no TestParser functions and ugly sample output in benchmark files).
