Integrate:

Duplicate 19423 (pathological hashes too easy) into hv_store_ent
(the routine used by perl level HV operations)

[ 21469]
Duplicate 19423 (pathological hashes too easy) into share_hek_flags
(as suggested by Jan Dubois)

[ 21471]
Plan C for foiling the algorithmic complexity attack
(based on Chip's plan A (binary compatibility with 5.8.0 and 5.8.1),
 Chip's plan B (do something new inside the hv functions)
 and introspective sort)
Provides infrastructure for hashes to change their hash function
if necessary, and code in hsplit to detect pathalogical data and
instigate a random rehashing.
Needs refinement. Let's see how much smoke it creates.

[ 21474]
Plan C rough edge smoothing - forgot to turn on the "has key flags"
flag on the hash when rehashing. Can turn off the "rehasing" flag
if the hash is cleared
