[PATCH] Make default_handler handle all requests

[Justin Erenkrantz <je...@apache.org>]

According to rbb on IRC, default_handler should always accept
all requests and it alone generates the appropriate HTTP error
codes.  I gave up arguing with him about this because I wasn't
getting anywhere and we were arguing about the placement of
code rather than what the code should do.  So, here's a
patch - untested.  I'll let the hordes test and commit it.

This would fix the 500 vs. 501 case where mod_autoindex refuses to
serve a request and default_handler returns DECLINED rather than
checking it for HTTP-compliance.

This reverts all of the changes to default_handler to only have it
serve 'default-handler' requests and delays checking for APR_DIR
until we know that we have a good method.  As a side-effect,
serving a directory that falls to default_handler would now
return 404 instead of 500 (which is probably better).  -- justin
