Msgqueue tests were using fork() to run create a separate thread of
execution for passing messages back and forth over a queue. However,
the child process after a fork() may only use async-signal-safe
functions, which at a minimum exclude gtest asserts.
Instead, use threads.

For file-based mmap tests, the underlying file system may not support
mmaps depending on the sandbox configuration. This is case when
caching is disabled for goferfs.

In this case, the task is already a subreaper, so setting this bit is a noop.

This change will allow us to remove the default link in a packetimpact test so
we can reduce indeterministic behaviors as required in https://fxbug.dev/78430.
This will also help with testing #1388.
Updates #578, #1388.

The self-admittedly arbitrary threshold of 20% of alarms being sent to the main
thread was being breached. I saw a run of of ~20-23% [1]. We should allow for a
little more breathing room.

This test single handedly causes the syscalls:socket_inet_loopback_test test
variants to take more than an hour to run on some of our testing environments.
Reduce how aggressively this test tries to replicate a fixed flake. This is a
regression test.

In gVisor today its possible that when trying to bind a TCP socket
w/ SO_REUSEADDR specified and requesting the kernel pick a port by
setting port to zero can result in a previously bound port being
returned. This behaviour is incorrect as the user is clearly requesting
a free port. The behaviour is fine when the user explicity specifies
a port.
This change now checks if the user specified a port when making a port
reservation for a TCP port and only returns unbound ports even if
SO_REUSEADDR was specified.

When TUN is created with IFF_NO_PI flag, there will be no Ethernet header and no packet info, therefore, both read and write will fail.

This allows these tests, which can cause flakiness when run in the same network
namespace as the other `socket_inet_loopback` tests, to run as separate tests
in their own environment. It also means that all of the shards of those tests
can be more isolated from each other as well.

tcpdump is largely supported. We've also chose not to implement writeable
AF_PACKET sockets, and there's a bug specifically for promiscuous mode (#3333).

Later kernels add empty arguments to argv, throwing off return values for the
exec_basic_workload.cc binary. This is result of a bug introduced by
ccbb18b67323b "exec/binfmt_script: Don't modify bprm->buf and then return -
ENOEXEC". Before this change, an empty interpreter string was reported if the
first non-space/non-tab character after "#!" was '\0' (end of file, previously-
overwritten trailing space or tab, or previously-overwritten first newline).
After this change, an empty interpreter string is reported if all characters
after "#!" are spaces or tabs, or the first non-space non-tab character is at
i_end, which is the position of the first newline after "#!". However, if
there is no newline after "#!" (as in ExecTest.InterpreterScriptNoPath),
then i_end = buf_end (= bprm->buf + sizeof(bprm->buf) - 1, the last possible
byte in the buffer) and neither condition holds.
Change white space for script inputs to take into account the above bug.
