Fix building on Windows.

[nopjmp]

This fixes building on Windows. We disable reordering and fix iridium to link correctly on Chromium 55. We still download syzygy for now until we decide if we want to keep it. icu_use_data_file has to be enabled on Windows for now to get it to at least build. Patches are not read into memory and piped over stdin anymore.

We can just kill syzygy building/downloading all together if you like, but I think it may be worth looking into at some point if performance or linking problems come up.

Should fix both #137 #118

I do apologize for the terribly formatted git message. I was in a rush to get this pull request created before I went to bed to avoid another 24 hour wait.

I'll check 64bit build tomorrow.

The commit message is fine. Good implementation of the changes. We should probably disable downloading syzygy for now by commenting out the lines in extra_deps.ini so there won't be extra downloading.

Also what is the problem with the original code for patching? What kind of errors (or any output) do you get? The GNU patch utility I instructed users to use in BUILDING works on Windows 10.

The patch function outputs patching but it doesn't patch anything. I can look further into it. I'll disable the download when I test 64bit Sent from my android device.

That's really weird. I have no idea what can be causing that if the patch utility hasn't changed and buildlib's invocation of it hasn't changed. Maybe it's some weird Windows silent failure?

I think it might be due to how python is interacting with the shell, but stdin might have been acting strangely in my setup. I'm not using ActivePython, but the official release. It might work if I updated python 3 I just noticed I'm on a REALLY old version.

@nopjmp Ah yeah Python 3.5 changed some stuff with the subprocess module. You should upgrade since I haven't tested the behavior with Python 3.4 on Windows (someone has on Debian Jessie though, but it's different from Windows).

[nopjmp]

@Eloston 64bit builds, but I need to fix GN bootstrap.py to compile for 64bit. Otherwise, it works just fine. I'll try to clean it up today if I have time; otherwise, it will be done tomorrow. I'll test Python3.5 also.

[Eloston]

@nopjmp Alright sounds good. Glad to hear that we're almost there.

[nopjmp]

Windows 64bit is fixed and I reverted the hacked up patch function.

[Eloston]

Perfect. Even all of the patches and code are consistent in style with everything else. Thanks for the great work!
