Change the way the polling system is selected

All polling systems are now checked and corresponding macros set
accordingly (e.g. detection of a working poll() function will define
XS_HAVE_POLL). Additionally if the user selects a specific polling
system via the --with-poller switch a corresponding XS_FORCE_* macro
will be defined. The select() and poll() tests now conditionally include
headers which makes them more robust on various target platforms.
