Feature checks are introduced to check for all the headers required by
the select() and poll() calls. Include files are then included
conditionally without the use of any OS-specific directive. The change
also fixes a couple of problems:
- Fixed compilation under FreeBSD, NetBSD and OpenBSD when forcing the
use of select() in the poller
- Quieted a warning mixed-sign comparison warning on FreeBSD caused by
FD_SETSIZE being declared as an unsigned constant on that OS
- Removed the obsolescent AC_HEADER_TIME macro from the configure script

This patch provides a single place for selecting polling mechanisms
(polling.hpp). Up to now the selection was spread among the build
system and several source files.

While --with-poller configure option could be used for selecting
the polling mechanism for I/O threads (asynchronous), synchronous
polling (xs_poll, signaler_t) was not affected by the option.
This patch uses selected mechanism is it is either 'select' or 'poll'.
Othrwise it chooses the mechanism according to the platform.

Originally, the parameter was of type long which is incompatible
with POSIX poll() function.

The timeout should be int. For historical reasons, however,
it is defined as long. To fix the problem the value is
checked in the runtime to assure it is not larger than INT_MAX.
