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.
