[RFC/PATCH 00/14] Build git with MSVC

So, Frank Li started this series, and I took it upon my self to help out a bit; cleaning, reorganizing, rebasing the series. Hopefully we're now a bit closer to including the series into mainline..

Here's a summary of what has happend:
1) This series is rebased ontop of git.git 'next', which needed an
   extra patch to avoid a non-constant array creation, which
   mscv doesn't like.
2) I've polished (tied to anyways) the commit messages a bit.
3) I've applied much of the feedback provided to the first round of
   the patches.
4) I've split, merged and reordered some of the patches, so things
   that belong together are in the same commits, and in a order of
   'importance'
5) I've removed the
       #define func _func
   stuff, as it's not needed and Microsoft cannot really kill the
   compatibility functions anyways. So, adding the define
       _CRT_NONSTDC_NO_DEPRECATE
   will kill the warnings seen without the defines above.
6) ..probably much more as well, but I forget..

Note: I did not sign off on the last two commits, which involve the
adding of the vcproj files, since I don't agree on adding them as is.
We need a Makefile way of compiling primarily, and second, a script
to generate the vcproj, as already discussed. But the commits are
included for completeness, at to let others compile and play with it.

I've kept the original author as is, and just signed the patches.. Thanks for watching, now bring on the comments!
