docs: update the PACKAGING docs

[Dimitrie O. Paun]

This belongs in the Packaging Guide more than in the
Devel Guide. The Devel Guide is still work in progress,
but meanwhile this can go in.

ChangeLog
    Add blurb about soft/hard dependencies to the Packaging Guide,
    based on a contribution by Shachar Shemesh.

+DEPENDENCIES
+~~~~~~~~~~~~
+
+There are two types of dependencies: hard and soft dependencies.
+
+A hard dependency must be available at runtime for Wine to function,
+if  compiled into the code. Soft dependencies on the other hand
+will degrade gracefully at runtime if unavailable on the runtime system.
+Ideally, we should eliminate all hard dependencies in favour of
+soft dependencies.
+
+To enable a soft dependency, it must be available at compile time.
+As a packager, please do your best to make sure that as many soft 
+dependencies  are available during compilation. Failing to have a 
+soft dependency available means that users cannot benefit
+from a Wine capability.
+
+Here is a list of the soft dependencies. We suggest packagers
+install each and every last of those before building the package. 
+These libraries are not dependencies in the RPM sense. In DEB packages, 
+they should appear as "Suggests" or "Recommends", as the case may be.
+    * FreeType: http://www.freetype.org
+      This library is used for direct rendering of fonts. It provides 
+      better support of fonts than using the X11 fonts engine. It is 
+      only needed for the X11 back end engine. Used from GDI.
+
+    * Alsa: "http://sourceforge.net/projects/alsa (Linux only)
+      This library gives sound support to the Windows environment.
+
+    * JACK: http://jackit.sourceforge.net
+      Similar to Alsa, it allow Wine to use the JACK audio server.
+
+    * CUPS: http://www.cups.org
+      This library allows Windows to see CUPS defined printers.
+
+    * OpenGL
+      This is used for both OpenGL and Direct3D (and some other 
+      DirectX functions as well) support in Wine. There are many many 
+      libraries for providing this functionality. It is enough for one
+      of them to be available when compiling Wine. Wine can work with 
+      any other library during runtime.
+      If no library is available, packagers are encouraged to compile 
+      Wine with Mesa3D (http://www.mesa3d.org), which requires no 
+      hardware support to install.
