config.h can't be prefixed unconditionally
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.

[core] re-order fields in struct event for memory efficiency
The sizeof `struct event` can reduced on both 32 bit and 64 bit systems
by moving the 4 bytes that make up `ev_events` and `ev_res` below `ev_fd`,
before `struct event_base * ev_base;` since our compiler wouldn't dare do
such a thing (it instead will pad twice, whereas it only needs to be padded
once)
```C
struct event {
/* OFFS | SZ Bytes | Total Bytes | START - END */
struct event_callback ev_evcallback; /* 0x0 | 40 | 40 | 0x0 - 0x28 */
union { /* 0x28 | ----------- | ----------- | ------------ */
TAILQ_ENTRY(event) ev_next_with_common_timeout; /* | ((16)) | | */
int min_heap_idx; /* | ((04)) | | */
} ev_timeout_pos; /* | 16 | 56 | 0x28 - 0x38 */
int ev_fd; /* 0x38 | 04 | 60 | 0x38 - 0x3c */
```
Since the next field is 8 bytes in length, and we are up to 60 bytes, `ev_fd` ends up being padded (4 more bytes on 64b).
```C
/* --- 1 byte gap HERE ---> 1 | <61> */
/* --- 1 byte gap HERE ---> 1 | <62> */
/* --- 1 byte gap HERE ---> 1 | <63> */
/* --- 1 byte gap HERE ---> 1 | <64> */
struct event_base * ev_base; /* 0x3c | 8 | 68 | 0x3c - 0x40 */
union { /* 0x40 | ------------ | ---------- | ------------ */
struct { /* | ------------ | | */
LIST_ENTRY (event) ev_io_next; /* | ((16+ | | */
struct timeval ev_timeout; /* | 16)) | | */
} ev_io; /* | ((32)) | | */
struct { /* | ------------ | | */
LIST_ENTRY (event) ev_signal_next; /* | ((16+ | | */
short ev_ncalls; /* | 02+ | | */
short * ev_pncalls; /* | 08)) | | */
} ev_signal; /* | ((26)) | | */
} ev_; /* 0x60 | 32 | 100 | 0x40 - 0x60 */
short ev_events; /* 0x60 | 2 | 102 | 0x60 - 0x62 */
short ev_res; /* 0x62 | 2 | 104 | 0x62 - 0x64 */
```
We now hit another line, `struct timeval` is 16 bytes on 64b arch, so we have 4 more bytes
of padding on `ev_res`.
```C
/* --- 1 byte gap HERE --- */
/* --- 1 byte gap HERE --- */
/* --- 1 byte gap HERE --- */
/* --- 1 byte gap HERE --- */
struct timeval ev_timeout; /* 0x64 | 16 | 120 | 0x64 - 0x74 */
};
```
After moving `ev_events` and `ev_res` below `ev_fd` we have something
a bit more optimal:
```C
struct event2 {
/* OFFS | SZ / Bytes | RSUM Bytes | START - END */
struct event_callback ev_evcallback; /* 0x0 | 40 | 40 | 0x0 - 0x28 */
union { /* 0x28 | ------------ | ---------- | ------------ */
TAILQ_ENTRY(event) ev_next_with_common_timeout; /* | ((16)) | | */
int min_heap_idx; /* | ((04)) | | */
} ev_timeout_pos; /* | 16 | 56 | 0x28 - 0x38 */
int ev_fd; /* 0x38 | 4 | 60 | 0x38 - 0x3c */
short ev_events; /* 0x3c | 2 | 62 | 0x3c - 0x3e */
short ev_res; /* 0x3e | 2 | 64 | 0x3e - 0x40 */
struct event_base * ev_base; /* 0x40 | 8 | 74 | 0x40 - 0x48 */
union { /* 0x48 | ------------ | ---------- | ------------ */
struct { /* | ------------ | | */
LIST_ENTRY (event) ev_io_next; /* | ((16+ | | */
struct timeval ev_timeout; /* | 16)) | | */
} ev_io; /* | ((32)) | | */
struct { /* | ------------ | | */
LIST_ENTRY (event) ev_signal_next; /* | ((16+ | | */
short ev_ncalls; /* | 02+ | | */
short * ev_pncalls; /* | 08)) | | */
} ev_signal; /* | ((26)) | | */
} ev_; /* | 32 | 106 | 0x48 - 0x68 */
struct timeval ev_timeout; /* 0x68 | 16 | 120 | 0x68 - 0x78 */
};
```
We still have a gap here, but the first was removed.
Again, we can save 8 bytes on both 32 and 64 word sizes (32/64 byte cacheline).

Fix CheckFunctionExistsEx() cmake macro on win32
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()).

- 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.

Do not ship evconfig-private.h in dist archive
It will be generated by autotools, so there is not reason to include it.
And infact this breaks compilation with out-of-tree builds (VPATH),
since, for the quote form of the include directive, headers in the
directory of the file with the #include line have priority over those
named in -I options, the copy of evconfig-private.h from the source
directory had priority over the one in the build directory.

Avoid possible SEGVs in select() (in unit tests)
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.

Fix base unlocking in event_del() if event_base_set() runned in another thread
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.

Immediately stop trying to accept more connections if listener disabled
This is a refined version of the logic previously in #578
The rationale is that the consumer of sockets may wish to temporarily
delay accepting for some reason (e.g. being out of file-descriptors).
The kernel will then queue them up. The kernel queue is bounded and
programs like NodeJS will actually try to quickly accept and then close
(as the current behaviour before this PR).
However, it seems that libevent should allow the user to choose whether
to accept and respond correctly if the listener is disabled.

This reverts commit a695a720cda892c270736d127333d73553842094.
@kgraefe:
"I believe that this commit is just wrong: if lev->cnt is not 1 after
the callback, new_fd will still never be closed in listener_read_cb().
So in that case it is the responsibility of the user's code to close
the file descriptor (which is fine). But why shouldn't it be in the
other case? And how does the user's code know?"
And I agree

Allow bodies for GET/DELETE/OPTIONS/CONNECT
I checked with nginx, and via it's lua bindings it allows body for all
this methods. Also everybody knows that some of web-servers allows body
for GET even though this is not RFC conformant.

Do not crash when evhttp_send_reply_start() is called after a timeout.
This fixes the crash reported in issue #509. The "would be nice"
items discussed in #509 can be addressed separately.

Fix crashing http server when callback do not reply in place
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.

Since it can arrive after we disabled events in that bufferevent and
reseted fd, hence evhttp_error_cb() could be called after

Remove OpenSSL paragram from README
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).

configure: avoid false positive in DragonFlyBSD
by default, the max buffer size is 16K and histeresis is at 50%, so
a bigger read is needed to unlock writes than you would expect from
other BSD (512 bytes)
this doesn't introduce any regression on FreeBSD 11.1, OpenBSD 6.1, NetBSD 7.1,
macOS 10.12.6 and of course DragonFlyBSD 4.8.1, and most of them show
a max pipe size of 64K, so the read call should drain them all regardless
of how conservative they are on the free pipe space they will require
(usually 512 bytes) before kevent reports the fd as ready for write.
I couldn't find a reference to which bug this code was trying to look for
and it seems to be there from the beginning of git history so it might be
no longer relevant.

Remove check against passed bufferevent in bufferevent_socket_connect()
It is a bit confusing to check against the result of EVUTIL_UPCAST(),
because it can return not NULL for NULL pointers, but for even though
with bufferevent we are fine (because bufferevent is the first field in
bufferevent_private), there are no checks for "bufev" in bufferevent's
API, so just remove it to make it generic.

Explicitly call SSL_clear when reseting the fd.
If reconnecting the via BEV_CTRL_SET_FD, bufferevent_openssl.c expects
OpenSSL to reuse the configuration state in the SSL object but retain
connection state. This corresponds to the SSL_clear API.
The code currently only calls SSL_set_connect_state or
SSL_set_accept_state. Due to a quirk in OpenSSL, doing this causes the
handshake to implicitly SSL_clear the next time it is entered. However,
this, in the intervening time, leaves the SSL object in an odd state as
the connection state has not been dropped yet. This behavior also does
not appear to be documented by OpenSSL.
Instead, call SSL_clear explicitly:

cmake: use APPEND during exporting targets (for old cmake)
On centos with cmake 2.8.12.2:
CMake Error at cmake/AddEventLibrary.cmake:92 (export):
export called with target "event_extra_shared" which requires target
"event_core_shared" that is not in the export list.
If the required target is not easy to reference in this call, consider
using the APPEND option with multiple separate calls.
But on newer cmake I guess everything is ok.
