CTest: Add support for Intel coverage files

By default, Intel compiler coverage tools generate HTML files as
reports, but the option -txtlcov can be given to codecov to output a
coverage file with LCov format.

To use Intel coverage:

* build the project with coverage flags
* run the application
* run profmerge
* run codecov

The output file will be "build_dir/CodeCoverage/SRCFILEDIR.LCOV".

Ask users to compile with -prof-dir${BUILD_DIR} instead of searching
the entire build tree recursively to find coverage files.
CPackDeb: Add option to set compression type

Add a CPACK_DEBIAN_COMPRESSION_TYPE option to set the compression type.
Default to 'gzip' to preserve existing behavior.  Use "cmake -E tar"
for 'gzip', 'bzip2', and 'none'.  Use system "tar" for 'lzma' and 'xz'.
