c-ares: ignore rogue DNS servers reported by windows

c-ares: libuv-ify c-ares

c-ares: upgrade to 1.9.0

test: fix test-gethostbyname to not use a DNS server on localhost

Because, you know, not everybody has one.

unix: speed up uv_async_send()

Don't make a syscall when the handle is already pending.

Speeds up the async_pummel benchmark by about 13%.

linux: fix accept4() ENOSYS detection on i386

accept4() piggybacks on the socketcall() on i386. socketcall() has the flaw
that it returns EINVAL instead of ENOSYS when the operation is not supported.

The problem is that accept4() also returns EINVAL when its flag argument is
invalid.

Try to discern between the two failure cases to the best of our abilities.

windows: don't inhibit reparse behavior when non-symlink is encountered

This fixes the issue that a mount point would be treated as a

windows: don't inhibit reparse behavior when non-symlink is encountered

This fixes the issue that a mount point would be treated as a
symlink, but readlink would subsequently return an NT namespaced
path that is unusable for many purposes.

This also pre-emptively fixes the problems that would arise when
an user has a reparse point whose tag is neither
IO_REPARSE_TAG_MOUNT_POINT nor IO_REPARSE_TAG_SYMLINK.

Finally uv_lstat() will now return the correct length in st_size.
Previously the length was computed incorrectly for relative
symlinks, and those that had non-ascii characters in their target.

unix: assume that dlopen() clobbers dlerror()

Or rather, don't assume that dlopen() does *not* clobber dlerror().

Joe Ferner reports that loading libjava on OS X sets dlerror() even when
dlopen() succeeds, which makes uv_dlopen() raise an error when it shouldn't.

I haven't been able to reproduce it but it's possible that libjava clobbers
dlerror() by trying (and failing) to load other libraries.

At any rate, Joe confirmed that this patch addresses the issue.

Fixes #462.
