Building w/o WFS/WMS/WCS support fails

[refractions]

When building without the pre-requisites for WFS/WMS/WCS (ie, OGR/GDAL and
PROJ), the code in mapwfslayer.c contains references to msOWSLookupMetadata
which is #def'ed out for this case. Either the mapwfslayer.c code needs to be
#def'ed out or the mapows.c code needs to be #def'ed in for this case, or
OGR/GDAL/PROJ need to be made into non-optional requirements.

Looking into this now.

Fixed in 4.4 CVS. I also rearranged things a bit to mark local functions
explicitly as static and #ifdef them all out.
