c4a6b56cc1 Fix unit test failures in response to DNS hijacking. 
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.

97ed2ce085 Unindent long-misindented blocks. 
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.

b317813485 Make GETINFO entry-guards work again with prop271 
This is not a great solution, but it's as close to
backward-compatible as possible.  A better GETINFO API should expose
more information.

04f21f0322 Remove abort handler from the backtrace generator 
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.

2f589e1057 Use event_base_new(), not event_init(), to detect libevent 2. 
(event_init() is obsoleted in libevent 2.)

Fixes bug 21051; bugfix on 0.2.9.1-alpha when we dropped libevent 1
support.

a757f76967 Withstand failures in CLOCK_MONOTONIC_COARSE 
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.

b6227edae1 Add a one-word sentinel value of 0x0 at the end of each buf_t chunk 
This helps protect against bugs where any part of a buf_t's memory
is passed to a function that expects a NUL-terminated input.

It also closes TROVE-2016-10-001 (aka bug 20384).
