  Signed to Unsigned Conversion Error - buffer.c:1623

  Description: This assignment creates a type mismatch by populating an
  unsigned variable with a signed value. The signed integer will be
  implicitly cast to an unsigned integer, converting negative values into
  positive ones. If an attacker can control the signed value, it may be
  possible to trigger a buffer overflow if the value specifies the length
  of a memory write.

  Remediation: Do not rely on implicit casts between signed and unsigned
  values because the result can take on an unexpected value and violate
  weak assumptions made elsewhere in the program.

And this is exactly what happend on:
- travis-ci
- #262

Here is a simple reproducer that I came up with for this issue:
  docker run --cpus=0.01 -e LD_LIBRARY_PATH=$PWD/lib -e PATH=/usr/bin:/bin:$PWD/bin -v $PWD:$PWD --rm -it debian:testing regress --no-fork --verbose bufferevent/bufferevent_timeout

Under limited CPU (see reproducer) the test almost always has problems
with that "write_timeout_at" exceed default timeval diff tolerance
(test_timeval_diff_eq() has 50 tolerance), i.e.:
  FAIL ../test/regress_bufferevent.c:1040: assert(labs(timeval_msec_diff(((&started_at)), ((&res1.write_timeout_at))) - (100)) <= 50): 101 vs 50

But under some setup write timeout can even not triggered, and the
reason for this is that we write to the bufferevent 1024*1024 bytes, and
hence if evbuffer_write_iovec() will has some delay after writev() and
not send more then one vector at a time [1], it is pretty simple to
trigger, i.e.:
  FAIL ../test/regress_bufferevent.c:1040: assert(labs(timeval_msec_diff(((&started_at)), ((&res1.write_timeout_at))) - (100)) <= 50): 1540155888478 vs 50

  [1]: https://gist.github.com/azat/b72773dfe7549fed865d439e03de05c1

So this patch just send static small payload for all cases (plus a few
more asserts added).

The outcome of this patch is that all regression tests passed on
travis-ci for linux box [2]. While before it fails almost always [3].
Also reproducer with CPU limiting via docker also survive some
iterations (and strictly speaking it should has less CPU then travis-ci
workers I guess).

bufferevent_socket_connect{,_hostname}() missing event callback and use ret code

- 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.

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

Image next situation:
  T1:                                        T2:

     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.
