Mega patch to improve how build dependencies are handled and

how packages are found.

First: I removed all these *-deps.db files and only a single file
is used now "build-depends.db"; it's smaller and will be easier
to handle in the future... when "run-depends.db" is added :-)

Second: there's no need to specify version of package anymore;
before you had to do:

	$ pkgfs.sh install git-1.6.0.2

now you only do:

	$ pkgfs.sh install git

This will read the variables located at PKGFS_TEMPLATESDIR/git.tmpl
and will the install the version that is there.

+ The X Rendering Extension introduces digital image composition as the
+ foundation of a rendering model within the X Window System.  Rendering
+ geometric figures is accomplished by client-side tessellation into either
+ triangles or trapezoids.  Text is drawn by loading glyphs into the server
+ and rendering sets of them.
+
+ This package contains the client library for connecting to a Xserver that
+ supports the Xrender extension.

+ This is the modular X.org X11 project version."
