Changing RewriteLocation default

[graygnuorg]

Pound assumes the RewriteLocation setting to be 1 by default. That default dates back to the days of version 2.8. However, due to the bug in RewriteLocation implementation, it wasn't actually working until the bug was fixed in version 4.13. It appears, however, that the fix brought quite some hassle for existing installations, which relied on RewriteLocation 0 behavior without requesting it explicitly (e.g. this issue). I must admit that my servers were affected as well :) That being said, I'm considering changing the default to 0, that is: no rewriting of Location and Content-Location headers.
