That way, when we are parsing the options and LearnCircuitBuildTimeout is set
to 0, we don't assert trying to get the options list with get_options().

The server-side clipping now clamps to one of two values, both
for what to report, and how long to cache.
Additionally, we move some defines to dns.h, and give them better
names.
In addition to the comments in the ticket, couple hidden service options have
been improved to clarify the maximum and minimum values they can be set to.

An operator couldn't set the number of introduction point below the default
value which is 3. With this commit, from 0 to the hardcoded maximum is now
allowed.

Our config code is checking correctly at DataDirectoryGroupReadable but then
when we initialize the keys, we ignored that option ending up at setting back
the DataDirectory to 0700 instead of 0750. Patch by "redfish".

In 8a0ea3ee43 we added a
temp_service_list local variable to rend_config_services, but we
didn't add a corresponding "free" for it to all of the exit paths.
Fixes bug 20987; bugfix on 0.3.0.1-alpha.
Some DNS NXDOMAIN hijackers hijack truly ridiculous domains, like
"invalid-stuff!!" or "1.2.3.4.5". This would provoke unit test
failures where we used addresses like that to force
tor_addr_lookup() to fail. The fix, for testing, is to mock
tor_addr_lookup() with a variant that always fails when it gets
a name with a !.
Fixes bugs 20862 and 20863.

(I have indeed verified that ed25519_fmt() is only used for
logging. This patch also clarifies the intention that ed25519_fmt()
is only for logging.
Closes ticket 21037.
Previously we were marking directory guards up in
..._process_inbuf(), but that's wrong: we call that function on
close as well as on success. Instead, we're marking the dirguard up
only after we parse the HTTP headers. Closes 20974.
The abort handler masks the exit status of the backtrace generator by
capturing the abort signal from the backtrace handler and exiting with
zero. Because the output of the backtrace generator is meant to be piped
to `bt_test.py`, its exit status is unimportant and is currently
ignored.
The abort handler calls `exit(3)` which is not asynchronous-signal-safe
and calling it in this context is undefined behavior [0].
Closes ticket 21026.
