win,node-gyp: optionally allow node.exe/iojs.exe to be renamed

On Windows, when node or io.js attempts to dynamically load a compiled
addon, the compiled addon tries to load node.exe or iojs.exe again -
depending on which import library the module used when it was linked.
This causes many compiled addons to break when node.exe or iojs.exe are
renamed, because when the binary has been renamed the addon DLL can't
find the (right) .exe file to load its imports from.

This patch gives compiled addon developers an option to overcome this
restriction by compiling a delay-load hook into their binary. The
delay-load hook ensures that whenever a module tries to load imports
from node.exe/iojs.exe, it'll just look at the process image, thereby
making the addon work regardless of what name the node/iojs binary has.

To enable this feature, the addon developer must set the
'win_delay_load_hook' option to 'true' in their binding.gyp file, like
this:

```
{
  'targets': [
    {
      'target_name': 'ernie',
      'win_delay_load_hook': 'true',
      ...
```

When resolving a reference URL with the 'file' scheme an no host

win,node-gyp: optionally allow node.exe/iojs.exe to be renamed

On Windows, when node or io.js attempts to dynamically load a compiled
addon, the compiled addon tries to load node.exe or iojs.exe again -
depending on which import library the module used when it was linked.
This causes many compiled addons to break when node.exe or iojs.exe are
renamed, because when the binary has been renamed the addon DLL can't
find the (right) .exe file to load its imports from.

This patch gives compiled addon developers an option to overcome this
restriction by compiling a delay-load hook into their binary. The
delay-load hook ensures that whenever a module tries to load imports
from node.exe/iojs.exe, it'll just look at the process image, thereby
making the addon work regardless of what name the node/iojs binary has.

To enable this feature, the addon developer must set the
'win_delay_load_hook' option to 'true' in their binding.gyp file, like
this:

```
{
  'targets': [
    {
      'target_name': 'ernie',

timers: do not restart the interval after close

Partially revert 776b73b24306bac0ce299df4f90b7645d5efca31.

Following code crashes after backported timer leak fixes:

```javascript
var timer = setInterval(function() {
  clearInterval(timer);
}, 10);
timer.unref();
```

Note that this is actually tested in a `test-timers-unref.js`, and is
crashing only with 776b73b24306bac0ce299df4f90b7645d5efca31.

Calling `clearInterval` leads to the crashes in case of `.unref()`ed
timers, and might lead to a extra timer spin in case of regular
intervals that was closed during the interval callback. All of these
happens because `.unref()`ed timer has it's own `_handle` and was used
after the `.close()`.

 * timers: two minor problems with timers have been fixed:
   - Timer#close() is now properly idempotent #1288 (Petka Antonov).
   - setTimeout() will only run the callback once now after an
     unref() during the callback #1231 (Roman Reiss).
 * Windows: a "delay-load hook" has been added for compiled add-ons

   users may be experiencing with add-ons in io.js #1251

js2c: fix module id generation on windows

Fix a regression that was introduced in commit 2db758c ("iojs: introduce
internal modules") where the computed id for "config.gypi" on Windows
was not "config" but an empty string.

With an empty string, the build succeeds but the binary is unusable:
startup.processConfig() in src/node.js chokes on the missing .config
property.

src: don't lazy-load timer globals

Don't lazy-load setInterval(), setTimeout(), etc.  Most applications are
going to need them and routing every call through NativeModule.require()
and Function#apply() is not exactly efficient.

win,node-gyp: make delay-load hook optional

The delay-load hook that was landed in 3d46fef to make compiled addons
work on Windows regardless of the iojs.exe/node.exe filename causes
issues with a small amount of compiled addons.

Therefore this patch makes it an opt-in feature. An addon may set the
'win_delay_load_hook' option to 'true' in its binding.gyp to enable this
feature.

Example:

```
{
  'targets': [
    {
      'target_name': 'ernie',
      'win_delay_load_hook': 'true',
      ...
```

timers: assure setTimeout callback only runs once

Calling this.unref() during the callback of SetTimeout caused the
callback to get executed twice because unref() didn't expect to be
called during that time and did not stop the ref()ed Timeout but
did start a new timer. This commit prevents the new timer creation
when the callback was already called.
