handling of reparse points

Hi,

It seems that svn doesn't handle reparse points properly in all
situations. Which causes big problems for TSVN when a working copy is on
a Onedrive folder.

See here for more details:

While in this particular situation, other svn clients are not affected,
it still means that there's a problem.

I've attached a patch for handling reparse points better when detecting
and reading the working copy database. With this change, the TSVN
context menu shows up properly.

But while I was trying to figure out this particular problem I noticed
that svn_io_check_path() never tries to resolve the reparse points. Why
is that? I mean if we need to check for links/reparse-points there's
svn_io_check_special_path(). Also, svn_io_check_path() always returns
node_file for reparse points, even if they point to directories.
IMHO handling links/reparse-points specially is only required in very
specific situations, like adding them. In most cases, resolving the
links/reparse points is what should be done. Or am I missing something
big here?
