poll: Prevent libevent from spinning if POLLNVAL occurs
This can happen, for example if libevent is being used to poll fds given
by another library where the other library closes the fds without
notifying the program using it that said fds were closed. In this case,
libevent will simply spin on poll() since there are active fds, but
won't call any event callback to handle the condition.
In epoll case after socket closed it automatically removed from epfd, so
IOW it will not spin in epoll* API, just a timeout.

tests: use waitpid(..., WNOWAIT) to fix failing of main/fork under solaris
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."

also if you run with --verbose (some race or what).
But linux doesn't support WNOWAIT in waitpid() so add detection into

test: replace sleeping with syncing pair in main/fork
About this syncing pair:
- read endpoint, must be blocked, to make it a checkpoint or smth like this
- write endpoint, must be nonblocking, to avoid readcb hung
During testing sometimes bufferevent/bufferevent_connect_fail_eventcb fails,
and after some digging I found that this was the case when connect() doesn't
return ECONNREFUSED immediately, and instead next operation will return it (in
our case evbuffer_read()->readv(), needless to say that after this
bufferevent_writecb() called and it checks error with getsockopt() but of
course it doesn't return any error), so this patch checks "errno" after
"readv()" and installs "bufev::connection_refused" flag, to handle this from
writecb and only once.

Merge branch 'appveyor-cmake-v6'
This patch set introduces matrix for appveyor and fixes bugs related to win32,
during debugging this matrix. This should greatly reduce number of work for
making a release ('check under windows' part only).
Right now tests on appveyor still failes in summary, but we should dig into
problems, not hide them.
Test matrix looks like this:
- autotools
- autotools --disable-openssl
- autotools --disable-thread-support
- autotools --disable-debug-mode
- autotools --disable-malloc-replacement
- cmake
- cmake -DEVENT__DISABLE_OPENSSL=ON
- cmake -DEVENT__DISABLE_THREAD_SUPPORT=ON
- cmake -DEVENT__DISABLE_DEBUG_MODE=ON
- cmake -DEVENT__DISABLE_MM_REPLACEMENT=ON
- cmake -DEVENT__ENABLE_VERBOSE_DEBUG=ON
- cmake -DCMAKE_C_FLAGS='-DUNICODE -D_UNICODE'
And takes 90min (was 7min, and this is the sad part).

be_filter: avoid data stuck under active watermarks
Suppose we have bufferevent filter attached to bufferevent socket.
Read high watermark for bufferevent filter is configured to 4096 bytes.
Socket receives 4343 bytes. Due to watermark, 4096 bytes are transferred
from socket input buffer to filter input buffer and 247 bytes are left
in bufferevent socket.
Suppose that no more data is received through socket.
At this point 247 bytes will sit forever in input buffer of bufferevent
socket.
The patch attached solves this issue registering read callback to
filter's input buffer if it reaches its read high water mark and data
was left in corresponding underlying's input buffer.
This read callback calls filter process input function as soon as filter
input buffer falls below its read high watermark and there still is data
left in underlying input buffer. Callback is deregistered as soon as
filter input buffer falls below its read high watermark.

Fix bufferevent_pair to properly set BEV_EVENT_{READING,WRITING} on flush.
Here's some fun. From `bufferevent.h`:
```
#define BEV_EVENT_READING 0x01 /**< error encountered while reading */
#define BEV_EVENT_WRITING 0x02 /**< error encountered while writing */
```
And from `event.h`:
```
/** Wait for a socket or FD to become readable */
#define EV_READ 0x02
/** Wait for a socket or FD to become writeable */
#define EV_WRITE 0x04
```
Library users have to be very careful to get this right; it turns out, the
library itself got this wrong in the `bufferevent_pair` code. It appears that
in most of the code, only `BEV_EVENT_FINISHED` will indicate whether it's read
or write; on error or timeout, it appears that "both" is assumed and not set in
the callback. I read through all the other places where `BEV_EVENT_FINISHED` is
passed to an event callback; it appears that the pair code is the only spot
that got it wrong.

buffer: evbuffer_add_buffer(): clean empty chains from destination buffer
@EMPanisset reported a problem (#358) with evbuffer_remove_buffer(), but
actually I think that the problem is in evbuffer_add_buffer() which introduces
this empty chain, all other callers (except evbuffer_prepend_buffer(), but it
doesn't have this problem though) should be safe.
And FWIW the only API that allows empty chains is evbuffer_add_reference(), and
we can add check there to avoid such issues, but for now I leaved this without
fixing, since I think that evbuffer_add_reference() with empty chains can be
used as a barrier (but this can be tricky).
