WL#1562 (Improving spatial code)
A set of changes improving our RTree indexes and fixed few bugs
found during the tests
myisam/rt_index.c:
Algorythm for picking the branch to insert was fixed.
pick_by_perimeter version of the algorythm added (mostly for testing
purposes)
myisam/rt_index.h:
minimal size of the page set to 1/3
It noticeable increases searching performance
myisam/rt_key.c:
counting of the size of the filled part of the page fixed
rtree_choose_key moved to rt_index.c
myisam/rt_key.h:
no need to make rtree_choose_key global
myisam/rt_mbr.c:
operations for counting the perimeter of MBR added
myisam/rt_mbr.h:
interface for rtree_perimeter_increase
myisam/rt_split.c:
my_multi_malloc changed with my_alloca
sql/spatial.cc:
LINESTRING object can consist of single point
