This commit changes src/tcp_wrap.cc and src/udp_wrap.cc just enough to get by (i.e. to compile and function correctly.) The new libuv API allows for more cleanup and deduplication but I'm saving that for another day.
* upgrade deps/uv/ to v0.11.12. * update files in src/ after a libuv API change.
Also remove unused src/stdio_wrap.cc
