[PATCH] interruptable accept

[Thomas Pfaff]

This patch is not 100% perfect and could be done better (faster response
on incoming signal) with async Events but this would require a much larger
patch (Call AsyncEventSelect, WaitForMultipleObjects (socket and signal),
check for pending connection and set socket back to blocking mode).
Therefore i decided to use select and check for signal every 100ms. IMHO a
max of 100 ms delay for a pending signal is acceptable here and is at
least better than the current implementation.
