Optimized GIS functions

Browse Source 
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)
