Implemented support for virtual packages.

Browse Source 
The patch adds 150 lines approximately. It is implemented by modifying
xbps_find_pkg_in_dict_by_name() and xbps_find_pkg_in_dict_by_pattern().

When no dictionary is returned if tries to find a virtual package by
looking at the "provides" array object, if found.

xbps-0.8.0 (???):
* Added support for virtual packages. A virtual package is one that doesn't
exist in the repository, but other packages can provide it. A new array
in the package properties dictionary has been added to specify which
virtual packages the package supports. As an example, the `rsyslog'
package provides the virtual package `syslog-daemon-0'. Other packages
can depend in `syslog-daemon>=0' and `rsyslog' will satisfy the dependency.
* Merged the `progress_callback' branch that makes possible to specify a
function callback to update progress while unpacking binary packages

* Improved package dependency sorting algorithm that uses less memory
and as bonus sorts all packages in the way they should be (previously
the sorting was a bit different for packages with no run-time dependencies).

* Hide implementation details in the API, so the ABI is not compatible
anymore with previous versions. ABI will be respected once the API
has been stabilized, but not for now.
* Many structural changes in the API. Made some stuff private and changed
some function arguments in the API, the ABI is not compatible anymore with
previous versions... anyway you shouldn't be using libxbps just yet.
The API documentation has been modified to stay in sync with reality.
