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.
Found using flake8 which gave the following output;
lintChanges.py:10:13: E225 missing whitespace around operator
lintChanges.py:25:1: E302 expected 2 blank lines, found 1
lintChanges.py:46:5: F841 local variable 'lines' is assigned to but never used
lintChanges.py:52:32: E228 missing whitespace around modulo operator
lintChanges.py:53:11: E201 whitespace after '('
lintChanges.py:56:41: E228 missing whitespace around modulo operator
Part of ticket 21096.
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.
Because <unset> makes more sense than AAAAAAAAAAAAAAAAAAA...
(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.

We switched these to be "if (1) " a while back, so we could keep
the indentation and avoid merge conflicts. But it's nice to clean
up from time to time.
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.
