Remove workaround code for bug539

Browse Source 
We fixed bug 539 (where directories would say "503" but send data
anyway) back in 0.2.0.16-alpha/0.1.2.19.  Because most directory
versions were affected, we added workaround to make sure that we
examined the contents of 503-replies to make sure there wasn't any
data for them to find.  But now that such routers are nonexistent,
we can remove this code.  (Even if somebody fired up an 0.1.2.19
directory cache today, it would still be fine to ignore data in its
erroneous 503 replies.)

o Removed code
- Removed workaround code to handle directory responses from
servers that had bug 539 (they would send HTTP status 503
responses _and_ send a body too). Since only server versions
before 0.2.0.16-alpha/0.1.2.19 were affected, there is no longer
reason to keep the workaround in place.
