b827a08284 Stop spawn test failures due to a race condition with SIGCHLD on process exit
When a spawned process forks, fails, then exits very quickly, (this
typically occurs when exec fails), there is a race condition between the
SIGCHLD handler updating the process_handle's fields, and checking the
process status in those fields. The update can occur before or after the
spawn tests check the process status.

We check whether the process is running or not running (rather than just
checking if it is running) to avoid this issue.

a6627fdb80 Remove the legacy_test_helper and legacy_setup wrappers
These wrappers went into place when the default type for our unit
test functions changed from "void fn(void)" to "void fn(void *arg)".

To generate this patch, I did the same hokey-pokey as before with
replacing all operators used as macro arguments, then I ran a
coccinelle script, then I ran perl script to fix up everything that
used legacy_test_helper, then I manually removed the
legacy_test_helper functions, then I ran a final perl script to put
the operators back how they were.

0243895792 Use coccinelle scripts to clean up our unit tests
This should get rid of most of the users of the old test_*
functions.  Some are in macros and will need manual cleanup, though.

This patch is for 13119, and was automatically generated with these
scripts.  The perl scripts are there because coccinelle hates
operators as macro arguments.

"The NULL pointer warnings on the return value of
tor_addr_to_in6_addr32() are incorrect. But clang can't work this
out itself due to limited analysis depth. To teach the analyser that
the return value is safe to dereference, I applied tor_assert to the
return value."

6150741791 Fixed fgets_eagain unit test.
On a non-blocking pipe fgets sets EAGAIN when it encounters partial lines. No
error is set on full lines or EOF. EOF is reached when the writing end of the
pipe is closed. Partial lines and full lines are both returned by fgets, EOF
results in NULL.

Mention of this behaviour can be found in #1903 and #2045.

58f4200789 Thread support is now required
Long ago we supported systems where there was no support for
threads, or where the threading library was broken. We shouldn't
have do that any more: on every OS that matters, threads exist, and
the OS supports running threads across multiple CPUs.

This resolves tickets 9495 and 12439.  It's a prerequisite to making
our workqueue code work better, since sensible workqueue
implementations don't split across multiple processes.
