Optimized GIS functions
heap/hp_delete.c: Added comments mysql-test/r/gis.result: Updated results after name changes (all results line are unchanged) mysql-test/r/show_check.result: Update test results after fix in hp_delete.cc mysql-test/t/gis.test: Changed table names to longer, hopefully non conflicting ones. Added missing drop table mysys/hash.c: Inendation cleanup mysys/tree.c: Updated comments Decrease tree->allocated on delete (for status) sql/field.cc: Added safety checking for GIS objects sql/gstream.cc: Added copyright message Made a lot of speed/space optimizations Changed class names to be MySQL compliant sql/gstream.h: Made a lot of speed/space optimizations Changed class names to be MySQL compliant sql/item_create.cc: Indentation fixup sql/item_geofunc.cc: Use new gis interface functions and new gis class names. Simple optimizations Indentation fixups Fixed a lot of unlikely but possible errors. sql/item_geofunc.h: Moved SRID_SIZE to spatial.h sql/spatial.cc: Added copyright message Made a lot of speed/space optimizations Changed class names to be MySQL compliant sql/spatial.h: Made a lot of speed/space optimizations Changed class names to be MySQL compliant Indentation fixes Use bool instead of int as result type for functions that only return 0 or 1 sql/sql_string.cc: Simple optimizations sql/sql_string.h: Simple cleanups sql/structs.h: Added LEX_STRING_WITH_INIT (needed by spatial.cc)
