[PATCH] fix for issue 2475: ignore case for hostnames (repost)

Hi,

this patch has been sitting on the mailing list for some weeks, so I thought I
bring it back under your attention.

Previous discussion on this patch can be found here:
http://svn.haxx.se/dev/archive-2006-03/0292.shtml

In short, the issue is that hostnames should be handled in an case-insitive way.
Subversion now does all its url handling case sensitive, which leads to certain
problems, eg. moving a file/folder between working copies that point to the
same repository but with different case will fail.

I propose to resolve it as such:
1. When creating a new working copy, make sure the hostname part of the url in
the entries file is stored in lowercase.
2. When reading from an 'old' working copy, lower the case of the hostname while
reading the url. This allows us to be still backwards compatible.

This patch contains both white & blackbox tests for this issue.

thanks for committing if accepted.

Lieven.
