As splice(2) is Linux-specific, mark it as unsupported on non-linux systems. Furthermore, if splice is requested in the config but unsupported by the platform, report a warning to the user and ignore the config setting.
Check that splice(2) is available through the SPLICE_F_MOVE flag. If it is not, do not build anything splice-related and fall back to the buffer pump.
ipf is not available, at least on Debian GNU/kFreeBSD.
TCP_KEEPIDLE and friends are not portable.
LIST_HEAD is also defined in sys/queue.h on kFreeBSD. Rename our implementation to RED_LIST_HEAD to avoid clashes. Note that LIST_HEAD is currently unused.

Hi,
These changes make redsocks 0.5 build on non-linux platforms (tested on Debian GNU/KFreeBSD) again. The most important change is making
splice(2)support optional at build- and run-time, as well as using theTCP_KEEPIDLEsocket options et. al only when available.Regards,
Apollon
