libclick: expose equivalent of "click info PACKAGE-NAME"

[Colin Watson]

upstart-app-launch and unity-scope-click both run "click info PACKAGE-NAME". We should expose equivalent library functionality.

[Launchpad Janitor (janitor)]

This bug was fixed in the package click - 0.4.18.1

---------------
click (0.4.18.1) trusty; urgency=medium

  [ Colin Watson ]
  * If a user attempts to install a version of a package that is already
    installed in an underlay database, then just register the appropriate
    version for them rather than unpacking another copy.
  * Make "click hook run-system" and "click hook run-user" consistently use
    the bottom-most unpacked copy of a given version of a package, and
    update hook symlinks and user registration symlinks if necessary.

click (0.4.18) trusty; urgency=medium

  * Give gir1.2-click-0.4 an exact-versioned dependency on libclick-0.4-0.
  * Use is_symlink helper method in a few more places.
  * Add a similar is_dir helper method.
  * Ignore extraneous non-directories when walking a database root in
    Click.DB.get_packages and Click.DB.gc.
  * Make the PackageKit plugin tolerate the "_removable" dynamic manifest
    key being changed to a boolean in the future.
  * Document that users of "_removable" should tolerate it being a boolean.
  * Use libclick when removing packages, listing packages, or searching
    packages via the PackageKit plugin.
  * Add libclick interfaces to get package manifests, both individually
    (LP: #1287692) and for all installed packages (LP: #1287693).
  * Override description-starts-with-package-name Lintian error for click;
    this is describing the system as a whole rather than naming the package.
  * Add libclick interfaces to get the list of frameworks supported by the
    current system (LP: #1271633) and various properties of those frameworks
    (LP: #1287694).
