Relays now respect their AccountingMax bandwidth again. When relays
entered "soft" hibernation (which typically starts when we've hit
90% of our AccountingMax), we had stopped checking whether we should
enter hard hibernation. Soft hibernation refuses new connections and
new circuits, but the existing circuits can continue, meaning that
relays could have exceeded their configured AccountingMax.
This commit rolls back some of the cpu-saving fixes, where we tried
to avoid calling so many of our events while we're off the network.
That's because PERIODIC_EVENT_FLAG_NEED_NET checks net_is_disabled(),
which returns true even if we're only in soft hibernation.
Fixes bug 32108; bugfix on 0.4.0.1-alpha.
* 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.
See: https://bugs.torproject.org/31810
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.

When tearing down all periodic events during shutdown, disable them first so
their enable flag is updated.
This allows the tor_api.h to relaunch tor properly after a clean shutdown.

Code adapted from Rob's proposed patch in #30344.
Also add a comment in connection_mark_for_close_internal_() on why we should
not be adding extra code there without a very good reason.
When encoding introduction points, we were not checking if that intro points
had an established circuit.
When botting up, the service will pick, by default, 3 + 2 intro points and the
first 3 that establish, we use them and upload the descriptor.
However, the intro point is removed from the service descriptor list only when
the circuit has opened and we see that we have already enough intro points, it
is then removed.
But it is possible that the service establishes 3 intro points successfully
before the other(s) have even opened yet.
This lead to the service encoding extra intro points in the descriptor even
though the circuit is not opened or might never establish (#31561).

The documentation for this function says that the smartlist can
contain NULLs, but the code only handled NULLs if they were at the
start of the list.
We didn't notice this for a long time, because when Tor is run
normally, the sequence of msg_id_t is densely packed, and so this
list (mapping msg_id_t to channel_id_t) contains no NULL elements.
We could only run into this bug:
* when Tor was running in embedded mode, and starting more than once.
* when Tor ran first with more pubsub messages enabled, and then
later with fewer.
* When the second run (the one with fewer enabled pubsub messages)
had at least some messages enabled, and those messages were not
the ones with numerically highest msg_id_t values.

Since Rust on macOS is slow, don't wait for the macOS Rust job to finish.
Instead, split rust into slow rust (macOS) and fast rust (Linux). And
allow the build to finish before slow rust finishes.
Also make sure that we have:
* a Rust build on each platform,
* a Rust build with each compiler, and
* a check on all our Rust builds.
Finally, sort builds: allow fail last, macOS first, slowest first.
Closes 31859 for 0.3.5.
Since Travis macOS has IPv6 support (and Travis Linux does not), chutney
will now run its IPv6 networks as part of Travis CI.
But since chutney is slow, don't wait for the macOS chutney to finish.
(Travis have fixed the duplicate notification bug in fast_finish. So we
can use fast_finish and allow_failure to finish early. Unfortunately,
allow_failure also means we ignore failures in macOS chutney.)
Also make sure that we have:
* a compile on each platform, with each compiler,
* a check on each platform, and
* a check on each compiler.
Finally, sort builds: allow fail last, macOS first, slowest first.
Closes ticket 30860.

This test failure happened due to a signed/unsigned integer
comparison.
This bug occurred on SunOS, it may also occur on other systems that
use signed char as the default. (And cast 1-byte integer constants
to an unsigned integer.)

The log mutex is dynamically initialized, guarded by log_mutex_initialized.
We don't want to destroy it, because after it is destroyed, we won't see
any more logs.
If tor is re-initialized, log_mutex_initialized will still be 1. So we
won't trigger any undefined behaviour by trying to re-initialize the
log mutex.
Part of 31736, but committed in this branch to avoid merge conflicts.
cb_buf_mutex is statically initialised, so we can not destroy it when
we are shutting down the err subsystem. If we destroy it, and then
re-initialise tor, all our backtraces will fail.

Frequently, when a patch fails, it has failures in several files.
Using the "-k" flag will let us learn all the compilation errors,
not just the first one that the compiler hits.

When processing a %included folder, a bug caused the pointer to
the last element of the options list to be set to NULL when
processing a file with only comments or whitepace. This could
cause options from other files on the same folder to be
discarded depending on the lines after the affected %include.
