linux/lwip: Wrap some IO posix functions * to workaourd the FreeRTOS EINTR issue (when building without lwip) * to correctly choose the sub-system based on fd (when building with lwip) -- passing control to either linux/system or to lwip This commit also addapts tapio-if to provide DHCP client by default and configurable settings for static IP
