Upgrade libjpeg to version 7.

As I was starting to attempt to compile leptonica and I ran into gcc not being
able to find stdint.h. I noticed that the busybox patch included took all
stdint.h includes out and re-added all the typedefs that were needed. I'm
wondering why this is the case. Why with the default installation can't we
include stdint.h (among other headers it seems)?

In any case I got parts of it to compile :). Now I need to compile some of the
external dependencies (libtiff, libpng, libnetpbm, etc.). I started compiling
libjpeg (in the upstream directory) and it looks like there is a newer version:
http://www.ijg.org/files/jpegsrc.v7.tar.gz which unfortunately fails to compile.
Here's a start at fixing it:
update url for regex3.8a
make nestedvm work with gcc-4.2

move some upstream materials from brianweb.net to nestedvm.org
clarify licensing
switch gcclass and classgen from darcs to git
Added/updated libraries: zlib, freetype, libpng, libiconv, gd

Bumped zlib version from 1.2.3 to 1.2.7
Bumped freetype version from 2.1.4 to 2.4.9
Added libpng 1.5.10
Added libiconv 1.14
Added gd 2.0.35

Only build static versions of these libraries
  (why would nestedvm ever need shared libs?)

Updated sourceforge download URL prefix

Commented out old freetype patches that I don't understand
and don't apply cleanly.  Tests seems to work OK.

Patched freetype test program to use newer (mandatory) include syntax
add zlib dependency for libpng
add freetype dependency for libgd
Add the ability to swap out stdio of a UnixRuntime
Add better support for Windows paths and file error handling
Fix a bug in InputOutputStreamFD

If the backing Java InputStream reads zero bytes, InputOutputStreamFD
will incorrectly report EOF.  Force a second read that conclusively
determines EOF.
