Changes since version 0.10.2:

* include: remove extraneous const from uv_version() (Ben Noordhuis)

* doc: update README, replace `OS` by `PLATFORM` (Ben Noordhuis)

* build: simplify .buildstamp rule (Ben Noordhuis)

* build: disable -Wstrict-aliasing on darwin (Ben Noordhuis)

* darwin: don't select(&exceptfds) in fallback path (Ben Noordhuis)

* unix: don't clear flags after closing UDP handle (Saúl Ibarra
  Corretgé)

The exceptfds set is for polling OOB data, not errors.

Fixes joyent/node#5155.

The antiquated gcc/clang that ships with Xcode emits waaaay too many
false positives.

Commit a9740c9b changed the name of the OS var to PLATFORM but forgot to
update the README.

Fixes the following warning:

  include/uv.h:236:30: warning: type qualifiers ignored on function
  return type [-Wignored-qualifiers]
   UV_EXTERN const unsigned int uv_version(void);

This is the first officially versioned release of libuv. Starting now
libuv will make releases independently of Node.js.

Changes since Node.js v0.10.0:

* test: add tap output for windows (Timothy J. Fontaine)

* unix: fix uv_tcp_simultaneous_accepts() logic (Ben Noordhuis)

* include: bump UV_VERSION_MINOR (Ben Noordhuis)

* unix: improve uv_guess_handle() implementation (Ben Noordhuis)

* stream: run try_select only for pipes and ttys (Fedor Indutny)

Changes since Node.js v0.10.1:

* build: rename OS to PLATFORM (Ben Noordhuis)

* unix: make uv_timer_init() initialize repeat (Brian Mazza)

* unix: make timers handle large timeouts (Ben Noordhuis)

* build: add OBJC makefile var (Ben Noordhuis)

* Add `uv_version()` and `uv_version_string()` APIs (Bert Belder)

Overrides the Objective-C compiler that is used. Defaults to $(CC).

This commit fixes two closely related integer overflow bugs:

* Timers with a timeout > INT_MAX cause uv__next_timeout() to return
  a negative value.

* Timers with very large timeouts (close or equal to ULLONG_MAX) run on
  the next tick.

In both cases, clamp the values to prevent the overflow from happening.

Fixes joyent/node#5101.

uv_timer_get_repeat() should return 0 for timers that haven't been
started.

Rename the OS make variable to PLATFORM, it conflicts with the OS env
var. That is, running `make` when the OS env var is set, may cause
spurious build breakage.

Fixes #737.

Its not necesary for TCP and other streams, since fd is always working
with kqueue there.

Make it understand FIFOs, character devices and sockets.

Fixes #740.

Inverts the meaning of the 'enable' argument. Before, it actually set
the UV_TCP_SINGLE_ACCEPT flag when enable=1. Now it clears it, which is
what uv-win does and what you would expect it to do.

When iocp sync bypass is in use libuv doesn't expect the system to
generate events when an i/o operation completes synchronously. However
when iocp emulation is enabled an event will always be generated because
SetFileCompletionNotificationModes() doesn't stop OVERLAPPED.hEvent from
becoming signaled.

This should fix joyent/node#4959.

Closes #738.

This error is raised when calling read() or write() on a directory.

A bit of googling turns up some cases where this error can be raised
that are not properly mapped to EISDIR, but are also cases that libuv
doesn't really care about, like the Password Manager API,
GetFirmwareEnvironmentVariable, or CreateTapePartition.

If libuv ever needs to handle these cases, then I suppose that the
ERROR_INVALID_FUNCTION->EISDIR mapping could be done directly in the
fs read() and write() functions, but doing so at this point seems
premature, as it makes the error code mapping a bit more messy.

Fixes joyent/node#4951

Verify that our uv_buf_t type is ABI-compatible with struct iovec.

Replace a few internal functions in uv-common.h with macros to avoid
strict aliasing warnings with older versions of gcc.

It's not smart enough to figure out that e.g. a uv_tcp_t is an instance
of uv_handle_t with similar alignment requirements and therefore no
aliasing happens. More recent versions of gcc don't suffer from this.

I'm not normally in the habit of catering to compiler defects but the
aliasing warnings drown out legitimate warnings, hence the change.

Make the size of the thread pool configurable through an environment
variable. For sanity reasons, the size is clamped to the range 1-128.

Hopefully this fixes joyent/node#4809.

In very rare circumstances a uv_read_start() call on a uv_tty_t handle
in raw mode would return -1 but there was no actual failure. This patch
fixes that.

Fixes a busy loop when the file descriptor emits POLLHUP but not POLLIN
or POLLOUT, e.g. when polling the read end of a pipe and the write end
is closed.

Fixes joyent/node#4923.

Older versions of GYP would set up the Visual Studio project to link
with these libraries by default, but this was changed in r1584 (see
https://codereview.chromium.org/12256017).

Closes #728

Return an error when reading from /proc files fails because the procfs
isn't mounted.

We abuse uv_write2() to send over UDP handles to child processes.
Don't call uv__stream_fd() on those handles, it's a macro that on OS X
evaluates to a function that operates on a uv_stream_t with a couple of
OS X specific fields. On other Unices it does (handle)->io_watcher.fd,
which works but only by accident.

Fixes joyent/node#4870.

Only report as an error when status != 0.

Stops the platform_output test from being reported as having failed
on Jenkins.
