[WCS] All XML output should be encoded

[jlacroix]

In Bug 802, all metadatas and mapfile parameters have been HTML encoded to
prevent MapServer from outputing invalid XML file.

The same should be done for WCS.

This can be done easily by changing all msOWSPrintMetadata and msOWSPrintParam
to msOWSPrintEncodeMetadata and msPrintEncodeParam.

Check Bug 802 for more details.

Steve,
Is there anything to do in the WCS code for this? 

All value that we output to a XML document should be HTML encoded. I did not
touch it since I don't know what is the status of the code.

If nothing have to be done, please mark the bug as INVALID. And if you want me
to work on it, please reassign it to mapserver-bug at dmsolutions.ca

Just need to switch the calls as described in the original description. I can 
handle or you can too if you have the time. Are the msOWSPrintMetadata and 
msOWSPrintParam function still used at all then?

You can maybe do a grep, but I think that those two functions are only in
mapwcs.c now. I replaced all other occurence. I will leave it too you this bug
for now, if you don't have time let me know, but for this week I may be overbooked.

I think there may still be uses for the msOWSPrintMetadata() and
msOWSPrintParam() functions, so I would not take them out yet.

Fixed, just committed the changes for WCS.
