Checking functions with `CheckFunctionExists` may
get wrong results, we should replace it with
`CheckSymbolExists`, which is recommended by the cmake
official documentation.
Before using `CheckSymbolExists`, we use
`CheckIncludeFiles` to check header files and save the
available header files in a variable that guarantees
`CheckSymbolExists` and `CheckTypeSize` to work correctly.
This approach is modeled after the cmake scripts of `curl`.
The following functions or files were not found before
modification, they can now be found:
- msys2 + mingw-8.1.0 on Windows10 or mingw-7.3.0 on Ubuntu-18.04
timerclear
timercmp
timerisset

Moves the thread into real-time scheduling class, as recommended in [1], it
fixes the separate test provided by @ygj6 [2] everywhere (github actions,
travis-ci, appveyor) under osx.

Although even after this changes the following time-related tests failed
on travis-ci:
- no_events
- del_wait
But anyway I guess #940 can be closed, since this fixes the issue in common.
* osx-clock:
test: Use THREAD_* wrappers in del_notify/del_wait
test: move threads created with THREAD_START() to realtime scheduling class too
test: put thread into real time scheduling class on osx for better latencies

First of all __func__ is not a macro, it is char[] array, so the code
that we had before in cmake, was incorrect, i.e.:
#if defined (__func__)
#define EVENT____func__ __func__
#elif defined(__FUNCTION__)
#define EVENT____func__ __FUNCTION__
#else
#define EVENT____func__ __FILE__
#endif
So just detect do we have __func__/__FUNCTION__ in configure/cmake
before build and define EVENT__HAVE___func__/EVENT__HAVE___FUNCTION__
to use the later to choose which should be used as a __func__ (if it is
not presented).

This patchset fixes win32 builds after some previous patches (referenced
in particular commits), and also removes some quirks for win32.
* win32-fixes:
test: do not return void
log/win32: fix exporting extern variable
log-internal: missing extern "C"
log: remove USE_GLOBAL_FOR_DEBUG_LOGGING
cmake: Export missing symbols for win32
cmake: eliminate EVENT_BUILDING_REGRESS_TEST, since we link with shared libs
test: windows doesn't have WNOWAIT
cmake: clean not used #defines from event-config.h
cmake: add <pthread.h> only for non-win32
(cherry picked from commit d84f0205453941235b0e04729098d4329c189bba)
This patchset adds next missing things (in compare to autotools):
- pkgconfig
- event_pthreads/event_openssl
- compile shared/static libraries always
And some fixes, because it will not build after fixing other things:
- export missing symbols for cmake (-fvisibility=hidden)
* cmake-missing-bits:
cmake: support visibility for AppleClang too
cmake: fix export absolute path and relative path and cleanup a bit
cmake: generate and install pkgconfig files
cmake: build SHARED and STATIC libraries (like autoconf does)
cmake: add missing event_openssl/event_pthreads libraries
Export symbols for -fvisibility=hidden (under cmake)

Fixes in cmake, to make it more like configure and support some
cross-compiling.
* cmake-configure-fixes-v2:
cmake: fix extracting of the version from git (check for number of matches)
Detect arch4random_addrandom() existence
Use off_t instead of ev_off_t for sendfile() (fixes android build)
cmake: detect _GNU_SOURCE not by __GNU_LIBRARY__ only (fallback to _GNU_SOURCE)
Check for WNOWAIT in waitpid() in runtime (not in cmake/configure)
cmake: add <pthread.h> into CMAKE_REQUIRED_INCLUDES for sizeof(pthread_t)
cmake: fix values for #cmakedefine
cmake: drop duplicates from event-config template
cmake: add value for the #cmakedefine macros (like autoconf)
cmake: Fix checking of enum values from sysctl.h
(cherry picked from commit 5aade2d30b6c5eff226cbf7b63fda5a01987ba4f)

- Remove a redundant check on netdb.h (EVENT__HAVE_NETDB_H).
- Properly setup EVENT__SIZEOF_SSIZE_T for the case where "ssize_t" is
not "int".
- Remove unused EVENT__HAVE_PTHREAD.
- Set EVENT__HAVE_LIBZ instead of EVENT__HAVE_ZLIB (and remove the
latter).

According to solaris docs:
"One instance of a SIGCHLD signal is queued for each child process whose
status has changed. If waitpid() returns because the status of a child
process is available, and WNOWAIT was not specified in options, any pending
SIGCHLD signal associated with the process ID of that child process is
discarded. Any other pending SIGCHLD signals remain pending."
And interesting thing that it works if you add sleep(1) before waitpid(), and
also if you run with --verbose (some race or what).
But linux doesn't support WNOWAIT in waitpid() so add detection into
cmake/autotools.

Otherwise that #ifdef in visibility.h is useless, and __declspec(dllimport)

We had cmake and autoconf tests for the inet_aton function... but we
never actually use it any more.
(The autoconf tests still use the callability of inet_aton to decide
whether we need to link against -lresolv)
