Some requests may get response (evutil_addrinfo) from gaic_server_cb,
in case of cancel_event (10000ms) will not be fast enough.

test/regress_buffer.c:2360:2: runtime error: null pointer passed as argument 1, which is declared to never be null

tinytest uses another way of detecting test failures, it uses pipe
between child and parent, and if the test function in child returns OK
it writes OK flag into pipe, and reads it in parent.
However sanitizers uses atexit handlers to detect leaks, and this will
not detect failures in case of exit() will be called from the atexit
handlers, fix this by checking status after waitpid().

(cherry picked from commit 37dbb3508099d49748453166c1ee9ef1603fcf3a)
In some CMake integrations, portions of the toolchain may end up
defining CMAKE_USE_PTHREADS_INIT even when EVENT__DISABLE_THREAD_SUPPORT
is set for libevent. Modify the build to not rely on this side effect
of find_package(Threads, ...) [which could be done elsewhere] but instead
to use EVENT__HAVE_PTHREADS which is defined only on the desired codepath.
Without this change, affected builds fail as a result of event_pthreads source
files being built but with build defines which cause the build to fail.

v2 (by azat):
- drop package installations
- use local .abi-check over $HOME/abi-check for build dir
- drop regex check, simply use default values (too complex otherwise)
- use sub-shell to avoid cd back
- add missing quotes
- make the style uniq across the whole file (no tabs for indent, copy-paste?)
- drop `set -x`, use `bash -x abi-check.sh` over
- drop EVENT_ABI_CHECK
- use /usr/bin/env bash as shebang
- use `find | xargs` over `cp $(grep -v)`
- adjust markdown syntax in abi-check/README.md
- adjust link to the publicly available documentation
v3 (by azat):
- docker image
- git check-ignore
- make -j8
- allow to change defaults

- EV_CLOSED is EPOLLRDHUP in epoll
- EPOLLRDHUP reported w/o EPOLLHUP if the socket closed with shutdown(SHUT_WR)
- EPOLLRDHUP reported w/ EPOLLHUP if the socket closed with close()
so in this case epoll backend will detect this event as error
(EV_READ|EV_WRITE), since the epoll_ctl() will return EPOLLRDHUP with
EPOLLHUP set, but this is not correct, let's fix this.
Fixes: #984
(cherry picked from commit 972b456bf60e9a2f550ec45a14921c06e252c793)
* EV_CLOSED-and-EV_ET-fixes:
Avoid triggering wrong events with EV_ET set
epoll: handle EV_ET for EV_CLOSED too
test: cover EV_CLOSED with lots of possible scenarious
test: rename simpleclose to simpleclose_rw (since it works via write/read)
