Many small fixes uncovered by the testbed layer #02

 - failover recovery for valgrind support
 - better error reporting and detection for epoll support
 - better dependency detection and handling for ESI support
 - ARP build error on FreeBSD
 - hack: silence build error on ZPH QoS support (TODO fix)

TODO:
 - fix ZPH support for BSD (Bug 2537)
 - comm symbol duplication failures under gcc 4.3.2
