LDP: Refactor epoll_ctl wrapper.
- Add AF_UNIX transaction to sock_test_client/server echo test to verify mixed epoll ldp implementation. - Misc cleanup / refactoring of ldp code. - Fix LDP_DEBUG in test/socket_test.sh Change-Id: Ib524c824728f109007d8c4d07d74603b6c687902 Signed-off-by: Dave Wallace <dwallacelf@gmail.com>
