Implemented uv_run2

Allows for running the event loop in 3 modes:
* default: loop runs until the refcount drops to zero
* once: poll for events only once and block until one is h

unix: disable relaxed accept() by default

Don't use the relaxed accept() algorithm introduced in be2a217 unless
explicitly requested. It causes a 50+% performance drop on some node.js

kqueue: ignore ENOENT error

File descriptor might be closed during callback, all events that was reported
before the callback are not valid and trying to remove them will result
in ENOENT. This error can be safely ignored.

unix: don't memset(0) in uv_udp_init()

It's inconsistent with other init functions. In particular, it clobbers the
data field.

Fixes #655.

sunos: properly disarm PORT_LOADED fsevent watcher

Fixes a segmentation fault when the watched entity is changed after the watcher
has been closed.

test, bench: remove unused includes

test, bench: replace strlen() with sizeof()

test: fix -Wunused-result warnings

unix: fix event loop stall

Fix a rather obscure bug where the event loop stalls when an I/O watcher is
stopped while an artificial event, generated with uv__io_feed(), is pending.

unix: rework uv_cancel() api

Bert Belder informs me the current approach where a request is immediately
cancelled, is impossible to implement on Windows.

Rework the API to always invoke the "done" callback with an UV_ECANCELED error

Avoid the extra syscall, it's a no-op for non-listening sockets.

build: fix `make libuv.so CFLAGS=<options>`

Running a make target that builds the shared object while overriding the CFLAGS
variable from the command line, would fail with a relocation error:

relocation R_X86_64_32 against `.text' can not be used when making a shared
object; recompile with -fPIC

Fix that by adding -fPIC unconditionally.

windows: improve / fix uv_interface_addresses

* If GetAdaptersAddresses() failed, it would return UV_OK nonetheless,
but the `adresses` and `count` out parameters would not be set.

but the `adresses` and `count` out parameters would not be set.

* When adapters were enabled or added in between the two
GetAdaptersAddresses() calls, it would fail.

* In case of an out of memory situation, libuv would crash with a fatal
error.

* All interface information is now stored in a single heap-allocated
area.

wq doesn't have to be initialized, init_once() takes care of that.

Remove the initialization so it goes into .bss instead of .data.
