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

win,node-gyp: 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 makes it impossible to rename node.exe or iojs.exe, because when that happens the module can't find its dependencies.

With this patch, a delay-load hook is added to all modules that are compiled with node-gyp. The delay-load hook ensures that whenever a module tries to load imports from node.exe/iojs.exe, it'll just refer back to the process image, thus making it possible to rename the iojs/node binary.
