SWIG: Moved common SWIG syntax to ${libname}.i

Browse Source 
This commit moves common SWIG syntax to a ${libname}.i for sensor
libraries.  Much of the swig content was originally duplicated for
each wrapper language which has lead to inconsistencies between wrappers
over time.  This commit moves all swig syntax to a common file.  Language
specific swig syntax can be added with #ifdef SWIG<LANGUAGE>.

The src/CMakeLists.txt will look first for a language-specific .i file,
then fall back to ${libname}.i.  In this way, it's possible to override
the common ${libname}.i file.  If a fallback .i file does NOT exist,
UPM CMake will generate a simple interface file for all languages.

Example:
    If no src/abp/pyupm_abp.i and no src/abp/abp.i then
    generate ${CMAKE_CURRENT_BINARY_DIR}/abp.i

When src/CMakeLists.txt uses a common ${libname}.i, it adds a -module
<language>upm_${libname} to the swig command line.

In the example below, a -module argument is provided for both Java and
Javascript, while the python module takes all syntax from pyupm_abp.i.

    ---------------        ----------     ---------------------
    src/abp/abp.i          java           -module javaupm_abp
    src/abp/abp.i          javascript     -module jsupm_abp
    src/abp/pyupm_abp.i    python

This commit removes ~4500 redundant lines for the UPM repository and
helps promote uniformity for the SWIG'ed languages.
