Changes to standardize UIMA C++ build and packaging on Linux

The proposed modifications to the build process and to version numbering are described in the wiki page https://cwiki.apache.org/UIMA/proposed-changes-to-uima-c-build-and-packaging.html.

The build process will directly invoke the autotools command and will be invoked from the root of an SVN extract or unzipped source tarball.

Package version number and library version number will be handled separately. These will not be tied to UIMA Java SDK release numbers.

The library version number will be based on the libtool version numbering mechanism to better support backward compatibility of annotator binaries.
