windows: fix check in uv_tty_endgame()
unix, windows: do not set SO_REUSEADDR by default on udp

Add UV_UDP_REUSEADDR flag instead, which can be passed to uv_udp_bind.
If the udp handle is unbound when uv_udp_set_memberhsip or
uv_udp_set_multicast_interface is called, the handle will be bound with
UV_UDP_REUSEADDR set.
unix: add UV_HANDLE_IPV6 flag to tcp and udp handles
bsd: support IPv6 qualified link-local addresses
mingw: fix build with autotools
error: add EMLINK mapping

build: enable all compiler warnings
Revert "build: enable all compiler warnings"

This reverts commit f75bb7c3379d4398de8ed588a110aa7ab8708a91.

We need to figure out all those warnings before reapplying this patch.
fs: avoid using readv/writev where possible

The VirtualBox shared file system doesn't seem to be capable of
`readv()` syscall. Since we don't need them in the most of the cases
anyway, it won't hurt to just use `read()` and `write()` when we are
reading just one buffer.

see https://github.com/joyent/node/issues/7343 for details.

authors: remove duplicate entries
linux: reduce file descriptor count of async pipe

Reopen one of the pipe descriptors as read/write through the procfs.
Allows us to close the original pipe file descriptors, saving a file
descriptor on kernels that don't support eventfd(2).
sunos: support IPv6 qualified link-local addresses
windows: fix opening of read-only stdin pipes

Fix https://github.com/joyent/node/issues/7345

Google Chrome is launching native messaging hosts by invoking cmd.exe
with input/output redirected from/to named pipes. The host ends up
with a read-only handle to the stdin pipe. This is causing
SetNamedPipeHandleState to fail.
build: fix building with old versions of autoconf
