The file VERSION is now the sole-source of versioning.

The generated .spec files will been removed in the maintainer-clean targets
and have been removed from the repository.

By default a GIT build is done. To do a non-GIT build do:

 $ make TARGET IPA_VERSION_IS_GIT_SNAPSHOT=no

When updating the version you can run this to regenerate the version:

 $ make version-update

The version can be determined in Python by using ipaserver.version.VERSION

- Removing shebangs (#!) from a bunch of python libraries
- Don't use a variable name in init scripts for the lock file
- Keep the init script name consistent with the binary name, so renamed
  ipa-kpasswd.init to ipa_kpasswd.init
- Add status option to the init scripts
- Move most python scripts out of /usr/share/ipa and into the python
  site-packages directories (ipaserver and ipaclient)
- Remove unnecessary sys.path.append("/usr/share/ipa")
- Fix the license string in the spec files
- Rename ipa-webgui to ipa_webgui everywhere
- Fix a couple of issues reported by pychecker in ipa-python

Creation steps are currently done with:

  self.start_creation(2, "Create foo")
  self.step("do foo")
  self.foo()
  self.step("do bar")
  self.bar()
  self.done_creation()

This patch refactors that into the much more
straightforward:

  self.step("do foo", self.foo)
  self.step("do bar", self.bar)
  self.start_creation("Create foo")
