Set up gtkdoc for razor.

Despite its name, gtkdoc doesn't require gtk+ and is a nice way to
generate DocBook format API documentation.

Rename bash completion script to razor.sh

More suitable for installation into /etc/bash_completion.d.

Don't assume razor is being run locally in bash-completion.

Breaks when installed system wide.

When uniquifying properties, also sort them on the owning package.

This ensures that whenever two packages provide or (or require, obsolete
or conflict) the same property, they appear in the same order in the
propertys list of packages.

Call exit() instead of just returning if child fails.

Return if we fail to open root.

Introduce install/remove iterators.

These iterator constructors lets you pass in two sets and creates
an iterator for the packages to remove or the packages to install.
The iterators will step through the packages in a sequence that respects
the pre, post, preun and postun modifiers.

Right now, the install order isn't actually implemented, this patch just
implements the API changes and updates the applications.
