Modernize the buid system

I've replaced all autoconf deprecated macros.

I've updated the required dependencies too, all these packages are present in Debian stable or current Ubuntu (anyway, glade depends on GTK+ 2.18, which is only present in recent distributions)

New dependencies:
automake >= 1.10
autoconf >= 2.63
libtool >= 2.2.6
intltool >= 0.40.0
gtk-doc >= 1.11

Modernize autotools configuration.v2

Updated patch: clean autogen.sh and check for some more headers in conigure.ac

Modernize autotools configuration.v3

Finally a full working patch. I can relax some of the dependencies if you can (but autoconf 2.64 is needed for the URL paramater in AC_INIT())

New dependencies:
    automake >= 1.11
    autoconf >= 2.64
    libtool >= 2.2.6
    intltool >= 0.41.0
    gtk-doc >= 1.11

Please don't remove AM_MAINTAINER_MODE, it is prone to break some distribution builds. Instead you can use AM_MAINTAINER_MODE([enable]) to have a sane default for developers but still let distributors override it.

Modernize autotools configuration.v4

Updated patch with your comments

I've used AM_MAINTAINER_MODE([enable]) instead

For what I can see in the patch, it shouldn't break win32.
