Introduce two new APIs:
int uv_tcp_init_ex(uv_loop_t*, uv_tcp_t* handle, int flags)
int uv_udp_init_ex(uv_loop_t*, uv_udp_t* handle, int flags)
The lower 8 bits of the flags field are used for the socket domain.
AF_INET, AF_INET6 and AF_UNSPEC are supported. If AF_UNSPEC is specified
the socket is created lazily, just like uv_{tcp,udp}_init.
Some Windows notes:
getsockname fails with WSAEINVAL if the socket is not bound. This could
potentially be improved by detecting the socket family and filling
the sockaddr_in/6 struct manually.
bind returns WSAEFAULT if we try to bind a socket to the wrong family.
Unix returns EINVAL.

Some systems, FreeBSD for example, may return negative values.
sysconf() returns a long, which was being converted to a size_t.
This conversion lead to large allocations, and subsequent out of
memory failures. This commit checks the long value returned by
sysconf() properly, and uses a default value of 4096 if a negative
number is returned.

Apple's `fd_set` stores its bits in an array of 32-bit integers, which
means `FD_ISSET()` may read out of bounds if we allocate storage at
byte granularity. There's also a chance that the `select()` call could
corrupt the heap, although I didn't investigate that.
This issue was discovered by LLVM's AddressSanitizer which caught
`FD_ISSET()` trying to read out of bounds.

With uv_replace_allocator, it's possible to override the default
memory allocator's malloc and free calls with functions of the user's
choosing. This allows libuv to interoperate with projects requiring a
custom memory allocator.
Internally, all calls to malloc and free have been replaced with
uv__malloc and uv__free, respectively. The uv__malloc and uv__free
functions call malloc and free unless they have been overridden by a
previous call to uv_replace_allocator.
As part of this change, the special aligned memory allocations
performed in src/win/fs-event.c have been replaced with standard
allocations. The 4-byte alignment being requested in this file was
unnecessary, since standard allocators already guarantee at least an
8-byte alignment.

Commit 393c1c5 ("unix: set non-block mode in uv_{pipe,tcp,udp}_open")
causes a regression in the io.js cluster module.
The io.js documentation states that `worker.send()` and `process.send()`
are synchronous but they no longer were after upgrading to libuv v1.2.1.
The reason they are synchronous is because of backpressure - or rather,
lack of backpressure: a slow consumer eventually causes a fast producer
to run out of memory because the backlog of pending messages in the
producer can grow unchecked.
Ergo, implement uv_stream_set_blocking() on UNIX platforms to let io.js
enable the old blocking behavior for pipes again.
