Create an optional relay module, which can be disabled using the
--disable-module-relay configure option. When it is set, also disable
the dirauth module.
Add a minimal implemention, which disables the relay and dircache modes
in tor.
Closes ticket 32123.
* actually sleep when tor has not logged anything
* log at debug level when waiting for tor to log something
* backslash-replace bad UTF-8 characters in logs
* format control messages as ASCII: tor does not accept UTF-8 control commands
Fixes bug 31837; bugfix on 0.3.5.1-alpha.
This patch removes an overly strict tor_assert() and an ignorable BUG()
expression. Both of these would trigger if a PT was unable to configure
itself during startup. The easy way to trigger this is to configure an
obfs4 bridge where you make the obfs4 process try to bind on a port
number under 1024.

This patch adds a test to check for whether the exit callback is always
called when process_exec() fails, both on Windows and Unix.

This patch fixes an issue where the exit handler is not called for the
given process_t in case CreateProcessA() fails. This could, for example,
happen if the user tries to execute a binary that does not exist.

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.

We used to have this function so that we could mark our initial
log-to-stdout as specifically temporary so that we would delete it
once regular logs were configured. But it's no longer necessary to
mark these logs as temporary, since we now use a mark-and-sweep
process to ensure that _all_ not-configured logs are closed when we
change our configuration.
Instead, this function will be the basis of a refactoring in how we
handle default logs.
