Make ipaclient a Python library like ipapython, ipalib, etc.
Use setup.py instead of autotools for installing it.
Move C client tools, Python scripts, and man pages, to client/.
Remove old, empty or outdated, boilerplate files (NEWS, README, AUTHORS).
Remove /setup-client.py (ipalib/setup.py should be used instead).
Update Makefiles and the spec file accordingly.
