Actually, with trunk WordPress you can now set the home and siteurl
options in the wp-config.php file using the optional WP_HOME and
WP_SITEURL constants.  That would seem to take care of most the cases
you mention, except for absolute URLs within posts, which can be fixed
with the MySQL replace function.
