re-enable network support for 4.3.16

Issue #1296
dde_linux: remove bogus semicolon
ddekit: remove sleep_forever in dde_kit_debug

function to return. Since there is dde_kit_panic it should better
be used in such a case the output should block.
dde_linux: clean up usb patches
dde_linux: clean up lxip patches
dde_linux: remove base cxx dep from usb.inc
dde_linux: remove base cxx from lxip.mk
wifi_drv: Port of the Linux wireless stack
