This reverts commit 8f2a1f8a, reversing
changes made to ed7edadc.

This  merge introduced regressions in our build farm and revealed
issues in the DHCP4o6 IPC code. It also revealed some differences
in sockets handling under Linux and BSD. Rather than continue
patching this here, we should work on the branch to resolve all
issues and then merge 1.1.

Added missing fctnl.h include. Okayed on jabber.

Removed debug leftover and changed 'responds' to 'answers'.

src/bin/dhcp4/tests/dhcp4_srv_unittest.cc
    TEST_F(Dhcpv4SrvTest, emptyClientId)
        Added code to set up test interfaces

The use of .text isn't really clear yet and rather than confuse
users we are removing it from the documentation.
