aa69f34d53 windows: report spawn errors to the exit callback 
Formerly spawn errors would be reported as a message printed to the
process' stderr, to match unix behaviour. Unix has now been fixed to
be more sensible, so this hack can now be removed.

This also fixes a race condition that could occur when the user closes
a process handle before the exit callback has been made.

3f1f11f338 windows: use UV_ECANCELED to signal canceled requests 
This used to be UV_EINTR, but that's not an appropriate error code in

758a76922b unix: fix SIGCHLD race in process.c 
Start the SIGCHLD signal watcher before calling fork(). There was a very subtle
race where a child process could quit (and generate a SIGCHILD) before the
signal handler was installed.

To reproduce, call uv_spawn() repeatedly with the below x86_64 program:

    // compile with `gcc -O2 -nostdlib`
    void _start(void)
    {
      // syscall(SYS_exit, 0)
      __asm__ __volatile__ (
        "xorq %rdi, %rdi;"
        "xorq %rax, %rax;"
        "mov $0x3c, %al;"
        "syscall;"
      );
      for (;;);
    }

2c3e8b6aa6 build: rework -fvisibility=hidden detection 
Make the gcc_version macro conform with what node.js and v8 use. Important
because node.js's common.gypi is going to export it soon.

ac0d46851a unix: work around darwin bug, don't poll() on pipe 
poll() on newer versions of OS X sets POLLHUP|POLLIN whereas older versions
(and other Unices) only set POLLHUP. It was tripping up a check that expected
to read data when POLLIN was set.

While easy to work around, I switched it to a blocking read instead:
it's less code and avoids surprises like the one above altogether.

Fixes #522.

23dc564f3b darwin: emulate fdatasync() with fcntl(F_FULLFSYNC) 
OS X has no public API for fdatasync. And as pointed out in `man fsync(2)`:

  For applications that require tighter guarantees about the integrity of
  their data, Mac OS X provides the F_FULLFSYNC fcntl. The F_FULLFSYNC
  fcntl asks the drive to flush all buffered data to permanent storage.
  Applications, such as databases, that require a strict ordering of writes
  should use F_FULLFSYNC to ensure that their data is written in the order
  they expect.  Please see fcntl(2) for more detail.

5143d54ad3 Allow inclusion of <uv.h> with Sun Studio compiler 
The Sun Studio compiler did not define any of the symbols used to determine if
the system was a unix-like system or not causing it to include the windows
header.

their builds to fail due to warnings emitted from the headers.

d4737abd6d unix: remove dead code in process.c 
uv_spawn() saves and restores the environ in case the child clobbers it -
which is impossible because the child process runs in a separate address space.
