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.
These relays need to be contacted over their ORPorts using a begindir
connection, and relays try not to use begindir connections.
Fixes bug 20711; bugfix on 0.2.8.2-alpha.

(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.

Turning on warnings in Automake makes it complain about not using the
AM_PROG_AR macro. The AM_PROG_AR macro is required when LIBRARIES or
LTLIBRARIES is used.
The macro looks for an archiver and wraps it in the ar-lib script which
is automatically generated so Git should ignore it.
It makes the custom check for 'ar' obsolete so it is removed.
The AM_PROG_AR macro was added in Automake 1.11.2 thus the minimum
Automake version is increased.
When marking for close a circuit, the reason value, a integer, was assigned to
a uint16_t converting any negative reasons (internal) to the wrong value. On
the HS side, this was causing the client to flag introduction points to be
unreachable as the internal reason was wrongfully converted to a positive
16bit value leading to flag 2 out of 3 intro points to be unreachable.

First, this commit moves the code used to prune the service list when
reloading Tor (HUP signal for instance) to a function from
rend_config_services().
Second, fix bug #21054, improve the code by using the newly added
circuit_get_next_service_intro_circ() function instead of poking at the global
list directly and add _many_ more comments.
Fixes#21054.

This came up on #21035, where somebody tried to build on a linux
system with kernel headers including CLOCK_MONOTONIC_COARSE, then
run on a kernel that didn't support it.
I've adopted a belt-and-suspenders approach here: we detect failures
at initialization time, and we also detect (loudly) failures later on.
Fixes bug 21035; bugfix on 0.2.9.1-alpha when we started using
monotonic time.
