[WMS] output one SRS element per EPSG in mapwms.c

[tomkralidis]

This originated out of bug 1148, w.r.t. deprecated behaviour of elements with
space delimited lists of values, in favour of one element per list value.

If I issue OGC:WMS 1.1.1 GetCapabilities against latest CVS, SRSs are output one
per element at the LAYER level, i.e.:

<SRS>EPSG:4326</SRS>
<SRS>EPSG:42304</SRS>

..this behaviour should be put forth at the ROOT LAYER level, i.e. the
MAP/WEB/METADATA.  Currently, the element:

/WMT_MS_Capabilities/Capability/Layer/SRS

is output as:

<SRS>EPSG:4326 EPSG:42304</SRS>

..whereas we should change to:

<SRS>EPSG:4326</SRS>
<SRS>EPSG:42304</SRS>

..so the same behaviour in mapwms.c, line 1202 which is made at the LAYER level
should be replicated at the ROOT LAYER level, around line 1857.

ouch that's an ugly one!  Of course we should make sure that both cases share
the same code (i.e. by moving the code to a function)

Taking care of this one

I added a function in mapows.c to fix that bug.

int msOWSPrintEncodeParamList(FILE *stream, const char *name, 
                              const char *value, int action_if_not_found, 
                              char delimiter, const char *startTag, 
                              const char *endTag, const char *format, 
                              const char *default_value) 

This function parse a string and separate different element with "delimiter".
Other than that it works exactly like msOWSPrintEncodeMetadataList.

Marking as FIXED
