Casey Bodley c72007f076 name cache: LINK inserts target to name cache 
the link part of basic test7 was failing because LINK's target was still cached as a negative entry, leading to the error "can't stat newfile.0 after link".  the solution is to replace the negative entry with the real fh and attributes of the target file

so instead of doing RESTOREFH+GETATTR on the source file and calling nfs41_attr_cache_update(), nfs41_link() uses LOOKUP+GETATTR+GETFH to get attributes for the target file and passes them to nfs41_name_cache_insert() along with dst_dir's changeinfo.  because the source and target file will have the same fileid attribute, nfs41_name_cache_insert() will update the attributes of both at the same time.  added the target file as an optional return parameter

    <br/><span class="code">&gt; nfs_mount.exe -d Z</span></li>
</ol>
<h2>4. <a name="cthon">Connectathon</a></h2>
<h3>Requirements</h3>
<ul>
    <li><a href="http://www.cygwin.com" title="www.cygwin.com">Cygwin</a>, including packages gcc-core, make, sunrpc, time</li>
    <li>ms-nfs41-client source code (ported tests are located in <span class="filename">ms-nfs41-client\tests\cthon04</span>)</li>

</ol>
<h2>5. <a name="issues">Known Issues</a></h2>
<ul>
    <li>Mounts must be obtained through nfs_mount.exe, and not via 'net use' or 'Map Network Drive'.</li>
    <li>When nfs_mount.exe is run without arguments, it does not properly list mounted drives.</li>
    <li>If nfsd.exe is restarted while a drive is mapped, that drive needs to be remounted before further use.</li>
    <li>Symbolic links are not supported. Connectathon's basic test8 will not pass.</li>
    <li>Does not properly handle renaming a file on top of an existing open file- the existing file is removed on rename, and not preserved until last close.</li>
