change of polling engine

[Juraj Lutter]

Hi,

FWIW, configure called with —cc-opt="-DNXT_HAVE_EPOLL_EDGE=0 -DNXT_HAVE_EPOLL=0 -DNXT_HAVE_EVENTPORT=1"

gives:

checking for Linux epoll ... found
checking for Linux signalfd() ... found
checking for Linux eventfd() ... found
checking for kqueue ... not found
checking for Solaris event port ... found
checking for /dev/poll … found

thus, epoll is still being used and now even build fails:

src/nxt_epoll_engine.c: In function 'nxt_epoll_create':
src/nxt_epoll_engine.c:237:15: error: 'union <anonymous>' has no member named 'epoll'; did you mean 'poll'?
     engine->u.epoll.fd = -1;
               ^~~~~
               poll
src/nxt_epoll_engine.c:238:15: error: 'union <anonymous>' has no member named 'epoll'; did you mean 'poll'?
     engine->u.epoll.mode = mode;
               ^~~~~
               poll

Thanks

otis
