patch for mapogcsld.c/h

[Peter Freimuth]

Dear Mapserver-Dev Team,
I found a problem in mapogssld.c in context of using external Graphics.

I suggest to use  extGraphicName as SymbolName instead of the Unique
Name of  created TmpFileName. This will reduce the amount of
created       Symbols, and will also reduce the number of calls to
msHTTPGetFile(). Find attached the modified functions based on code of
current 4.10.0 Release.
I also insert a LIMIT Check for static symbolset.symbol[] in
msSLDGetGraphicSymbol to avoid a crash caused by inserting new Symbols.
Kindest regards,
Peter
