download_and_compile.sh: use getopt instead of bash's getopts. Add --help.
The main advantage of getopt is that it allows one to define long options. Help can now be obtained with 'download_and_compile.sh --help', in addition to the already-existing '-h' option. [ This is the getopt tool shipped in Debian's util-linux package, which is marked as Essential, therefore should always be present on a Debian system. ] Try to improve formatting of the --help message, so that it is better suited to document options that have a short as well as a long form. Make the presentation of this help message a bit more standard.
