add metadataLink to DescribeCoverage response

[tomkralidis]

Add:

1./

at the layer level, metadataLink as first element in
/CoverageDescription/CoverageOffering/ (before description).  This was done
already for bug 943, so same approach.  Example:

<metadataLink metadataType="other" xlink:type="simple"
xlink:href="[wcs_metadatalink_href]"/>

Code add:

add following to mapwcs.c, line 596:

  msOWSPrintEncodeMetadata(stdout, &(layer->metadata), "COM",
"metadatalink_href", OWS_NOERR, "  <me
tadataLink metadataType=\"other\" xlink:type=\"simple\" xlink:href=\"%s\"/>\n",
NULL);

Fixed. Are you getting sick of finding my "TODO's" in the source yet?

The XML comes out screwed up:

<metadataLinkother xlink:type="simple"/>

I figured it might, it's that change that Julien made with the OWS url 
printing function. I made note of the likely error, in addition to the ones 
you noted, in that bug and will let him fix it. The function is way too 
complicated to call...

Fixed in mapwcs.c CVS.  Thanks guys!
