Added --skip-test-db option to mysql_install_db. If specified, no test database created and relevant grants issued. Removed --skip-auth-anonymous-user option of mysql_install_db. Now it is covered by --skip-test-db. Dropped some Debian patches that did the same. Removed unused make_win_bin_dist.1, make_win_bin_dist and mysql_install_db.pl.in.
