This includes minor fix-ups:
* Handle SIGTERM in runsc debug, to exit gracefully.
* Fix cmd.debug.go opening all profiles as RDONLY.
* Fix the test name in fio_test.go, and encode the block size in the test.

Test failure happens when `echo` writes late:
* Server nc shuts down write when it sees EOF from stdin.
* Client nc closes the connection when it detects EOF from socket and no data
in internal write buffer.
Using `-q` flag to make server not shutting down write in the beginning, while
letting connection to be closed by client. As `-q` flag's default value varies
in different netcat versions, we always specify it to prevent future breakage.

- Tweak the benchmarks to work with b.N where appropriate. In many cases,
b.N was simply being ignored. This creates an implicit dependency in the
user passing a reasonable benchtime (less than or equal to the actual
runtime of the test, or using the X syntax) otherwise the test runs
forever.
- In cases where the above is impossible, explicitly set benchtime from
the test wrapper, to prevent the above behavior (tensorflow).
- Drop the *Reverse variants, which are simply hey benchmarks. We should
just add a hey benchmark. The platforms benchmarks already include a
native platform, and thus these benchmarks are incredibly confusing.
(In other words, BenchmarkNginxReverse has nothing to do with an nginx
benchmark for runsc.)
- Remove the redunant Harness object, which contains no state, in order
to slightly simplify the code.
- Make Block and Heap profiling actually work, but setting appropriate
runtime parameters (and plumbing them through the config).
- Split the profiling into two phases: start and stop, since some will
need to be started early, and others will need to happen at the end.

When the scaled receive window size > 65535 (max uint16), we advertise
the scaled value as 65535, but are not adjusting the saved receive
window value when doing so. This would keep our current window
calculation logic to be incorrect, as the saved receive window value
is different from what was advertised.

There are surprisingly few syscall tests that run with hostinet. For example
running the following command only returns two results:
`bazel query test/syscalls:all | grep hostnet`
I think as a result, as our control messages evolved, hostinet was left
behind. Update it to support all control messages netstack supports.
This change also updates sentry's control message parsing logic to make it up to
date with all the control messages we support.

SO_OOBINLINE option is set/get as boolean value, which is the same as linux.
As we currently do not support disabling this option, we always return it as
true.

- Skip the bazel clean command on the last run of the benchmark.
- Use --test.benchtime=1ns to force running the benchmark once

We do not rely on error for getsockopt options(which have boolean values)
anymore. This will cause issue in sendmsg where we used to return error
for IPV6_V6Only option. Fix the panic by returning error (for sockets other
than TCP and UDP) if the address does not match the type(AF_INET/AF_INET6) of
the socket.

For "hey", requests >= concurrency. b.N can be set by the
--test.benchtime={b.N}x. The previous setting of b.N * c
can be surprisingly slow for larger c.
Set the requests to max(b.N, c) and log to the user if it is c.

Without this change, this test produces quite opaque errors as valid TCP
segments are not logged; what we see in the end is any random traffic that
happened *after* the final TCP segment.

Recursive make is difficult to follow and debug. Drop this by using
internal functions, which, while difficult, are easier than trying to
following recursive invokations.
Further simplify the Makefile by collapsing the image bits and removing
the tools/vm directory, which is effectively unused.

Prior to this change tcpdump would fail to create its output file
because the destination directory was owned by root. This would later
cause killall to fail, as tcpdump was not running. Check exit code of
tcpdump/tshark to produce better error messages should this regress.

Don't propagate arbitrary golang errors up from fusefs because errors
that don't map to an errno result in a sentry panic.

With the recent changes db36d948fa, we try
to balance the receive window advertisements between payload lengths vs
segment overhead length. This works fine when segment size are much
higher than the overhead, but not otherwise. In cases where the segment
length is smaller than the segment overhead, we may end up not
advertising zero receive window for long time and end up tail-dropping
segments. This is especially pronounced when application socket reads
are slow or stopped. In this change we do not grow the right edge of
the receive window for smaller segment sizes similar to Linux.
Also, we keep track of the socket buffer usage and let the window grow
if the application is actively reading data.

The next test case is perfectly valid, which creates a test directory
with appropriate permissions and ensures that you can't create a file.
This test case assumes that the root directory has certain permissions.
In this case, we may have EROFS instead of a permission error, but it's
perfectly plausible that no error occurs at all. The test is not valid.

These options allow overriding the signal that gets sent to the process when
I/O operations are available on the file descriptor, rather than the default
`SIGIO` signal. Doing so also populates `siginfo` to contain extra information
about which file descriptor caused the event (`si_fd`) and what events happened
on it (`si_band`). The logic around which FD is populated within `si_fd`
matches Linux's, which means it has some weird edge cases where that value may
not actually refer to a file descriptor that is still valid.
This CL also ports extra S/R logic regarding async handler in VFS2.
Without this, async I/O handlers aren't properly re-registered after S/R.
