The script make-event-config.sed was mangling all the symbols by
prefixing them with "EVENT__". The problem here is that some
symbols aren't for local consumption within libevent, but rather
influence other system header files (ex: __USE_FILE_OFFSET64 is
used by dozens of header files including <sys/sendfile.h>).
As a workaround, all symbols starting with a capital letter only
(with the exception of STDC_HEADERS which must also be left
untouched) will be mangled.
Future contributors will need to be aware of this distinction.

For example under mingw64 it could not detect that strtok_r() exists,
because it checks with:
void *p = func_name;
And for this you need the function to be defined, so just sync our
CheckFunctionExistsEx.c with CheckFunctionExists.c from cmake (and later
we should drop them out) since it does correct things to detech
functions existence.
Also for WIN32 there is -FIwinsock2.h -FIws2tcpip.h, and I guess that is
not works for mingw gcc (since -F in gcc is framework, and in windows
-FI is like -include in gcc). But looks like we do not need them
already (due to fixed CheckFunctionExistsEx()).

P.S. and cleanup this test a little, with early-return.

- When socket() failed in bufferevent_socket_connect() , the event
callback should be called also in
bufferevent_socket_connect_hostname(). eg. when use
bufferevent_socket_connect_hostname() to resolve and connect an IP
address but process have a smaller ulimit open files, socket() fails
always but caller is not notified.
- Make bufferevent_socket_connect()'s behavior more consistent: function
return error then no callback, function return ok then error passed by
event callback.

Per the POSIX definition of select():
http://pubs.opengroup.org/onlinepubs/009696699/functions/pselect.html
"Upon successful completion, the select() function may modify the object
pointed to by the timout argument."
If "struct timeval" pointer is a "static const", it could potentially
be allocated in a RO text segment. The kernel would then try to copy
back the modified value (with the time remaining) into a read-only
address and SEGV.

Otherwise it will not reset timeouts for the IO, but other things should
still works correctly.
Also evbuffer_remove_buffer() could return 0, due to empty buffers, for
example during flushing bufferevent, so let's count this is BEV_OK too.

Image next situation:
T1: T2:
event_del_()
lock the event.ev_base.th_base_lock
event_del_nolock_() event_set_base()
unlock the event.ev_base.th_base_lock
In this case we will unlock the wrong base after event_del_nolock_()
returns, and deadlock is likely to happens, since event_base_set() do
not check any mutexes (due to it is possible to do this only if event is
not inserted anywhere).
So event_del_() has to cache the base before removing the event, and
cached base.th_base_lock after.

(cherry picked from commit 99d0a952dada771b91acf63f5208b994e80a2986)
General http callback looks like:
static void http_cb(struct evhttp_request *req, void *arg)
{
evhttp_send_reply(req, HTTP_OK, "Everything is fine", NULL);
}
And they will work fine becuase in this case http will write request
first, and during write preparation it will disable *read callback* (in
evhttp_write_buffer()), but if we don't reply immediately, for example:
static void http_cb(struct evhttp_request *req, void *arg)
{
return;
}
This will leave connection in incorrect state, and if another request
will be written to the same connection libevent will abort with:
[err] ../http.c: illegal connection state 7
Because it thinks that read for now is not possible, since there were no
write.
Fix this by disabling EV_READ entirely. We couldn't just reset callbacks
because this will leave EOF detection, which we don't need, since user
hasn't replied to callback yet.

Because it is mauvais ton to use binaries instead of normal packages
(like apt-get in debian, pacman in arch, and others).
Plus that link was borken and according to [1] OpenSSL do not ship
binaries officially.
And personally I don't think that this is not obvious that you need
openssl libraries to build libevent with it's support, and BTW you need
headers too (of course).
