Summary0003751: check against FD_SETSIZE for control pipes ignores MHD_USE_EPOLL_LINUX_ONLY
DescriptionIn a couple places, checks against FD_SETSIZE are ignored if MHD_USE_POLL is set but don't take into account MHD_USE_EPOLL_LINUX_ONLY
Steps To ReproduceStartup with too many sockets in use in the same process; found in 0.9.32 but the code hasn't changed since then
Additional InformationShould be a trivial fix

In src/libmicrohttpd/daemon.c, look for the error string "file descriptor for worker control pipe exceeds maximum value"
