[gdal-dev] Field value methods in wrappers

[Ari Jolma]

I added support for datetimes and lists into the wrappers. These are 
tested in the Perl tests. The wrappers need (but not require, i.e., swig 
does not fail) input and output typemaps for lists. I implemented them 
into the Perl wrappers so that they are recognized by their patterns, e.g.,

"int *nLen, const int **pList" for list output for integer lists

"int nList, int *pList" for list input for integer lists

I also noticed a potential problem. If a field get/set method is called 
with index that is out of bounds (0..GetFieldCount()-1) a segfault may 
follow. I added this test and also the mapping from field name to field 
index into the Perl code of the Perl wrappers. I removed the overlayed 
versions of the methods from Perl wrappers.
