The helper function is deprecated. The package gvisor.dev/gvisor/pkg/rand
depends on crypto/rand which performs worse thatn math/rand, the changes
are fine since they are not at any gVisor's hot path.
The ultimate goal is to migrate math/rand to math/rand/v2.
This utility creates a nested structure out of a flat list of fully-qualified
test names, and can then execute them using nested `t.Run`s that reflect the
hierarchy properly.
This is useful for CUDA sample tests, which are organized in a hierarchy.
This hierarchy isn't known at compile time, so it cannot be reflected using
plain `t.Run`s.

First, this change moves the internal config API to use flag.FlagSet, which
allows more flexibility and fixes many test usages.
Second, the runtime flags are validated during install. The platform is opened
and a warning issued if this fails, but this is not fatal.
This change requires moving the Makefile to --test_env, since the attribute
is not properly supported by test targets. Therefore, the targets can use args
while the Makefile must pass in configuration via --test_env.

Executing `select {}` to wait forever triggers Go runtime deadlock
detection and kills the child, causing the number actual processes
be less than expected.

The syscall package has been deprecated in favor of golang.org/x/sys.
Note that syscall is still used in the following places:
- pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities
are not yet available in golang.org/x/sys.
- syscall.Stat_t is still used in some places because os.FileInfo.Sys() still
returns it and not unix.Stat_t.

This creates a TTY pair and runs `/bin/sh` in interactive mode within it.
It provides useful helper functions to interact with the shell and read the
output of commands run within it.
This is meant to be used for testing upcoming changes allowing `runsc exec` to
work in `-detach=false -tty=true` mode.

This change adds a layer of abstraction around the internal Docker APIs,
and eliminates all direct dependencies on Dockerfiles in the infrastructure.
A subsequent change will automated the generation of local images (with
efficient caching). Note that this change drops the use of bazel container
rules, as that experiment does not seem to be viable.
