  o Minor bugfixes (process management):
    - Remove assertion in the Unix process backend. This assertion would trigger
      when a new process is spawned where the executable is not found leading to
      a stack trace from the child process. Fixes bug 31810; bugfix on 0.4.0.1-alpha.
Handle errors from execve() in the Unix process backend more gracefully. This patch removes a call to tor_assert_unreached() after execve() failed. This assertion leads to the child process emitting a stack trace on its standard output, which makes the error harder for the user to demystify, since they think it is an internal error in Tor instead of "just" being a "no such file or directory" error. The process will now instead output "Error from child process: X" where X is the stringified version of the errno value.
