New waveforms interface

Description

Incorporates the new waveforms interface.

Support calling C and python waveform models from C and python clients.

The standard functions XLALSimInspiralChooseFD(TD)Waveform and XLALSimInspiralChooseFD(TD)Modes remain backwards compatible.

New C functions have been added XLALSimInspiralGenerateFD(TD)Waveform(Modes) which replicate the old ones and support a more flexible input of the parameters. Equivalent functions exist for the python interface.

The LALSuite build system has been modified to support embedded python.

See here for a brief introduction on the new waveforms interface.

API Changes and Justification

Backwards Compatible Changes

• This change does not modify any class/function/struct/type definitions in a public C header file or any Python class/function definitions
• This change adds new classes/functions/structs/types to a public C header file or Python module

Backwards Incompatible Changes

• This change modifies an existing class/function/struct/type definition in a public C header file or Python module
• This change removes an existing class/function/struct/type from a public C header file or Python module

If any of the Backwards Incompatible check boxes are ticked please provide a justification why this change is necessary and why it needs to be done in a backwards incompatible way.
