We need a way to match pipelines with IPA modules, so add fields in
IPAModuleInfo to hold the IPA module API version number, the pipeline
name, and the pipeline version.
The module API version is used to determine the layout of struct
IPAModuleInfo.
Also update IPA module tests and Doxygen accordingly. Doxygen needs to
be updated to accomodate __attribute__((packed)).

Define an IPAInterface class which will contain an IPA implementation.
The methods that the IPAInterface exposes form the interface to the IPA
implementation, hence the name. IPA module shared objects will implement
this class.
This also means that IPA module shared objects must be implemented in
C++, so remove the C test IPA module.

Implement a class to wrap around an IPA module shared object.
For now, just load a struct IPAModuleInfo with symbol name
ipaModuleInfo from an IPA module .so shared object.
Also provide a public header file including the struct IPAModuleInfo,
structured such that both C and C++ IPA modules are supported.
