Undefended King Ring
There was already a penalty for squares only defended by King (undefended)
This test records a penalty for completely undefended squares in the so called extended king-ring
(so if we exclude squares defended by a Kg8 for example, we only look at h6 g6 and f6)
We also exclude squares occupied by opponent pieces in this computation,
based on the following results

Backward simplication
On top of the usual conditions
a) some opponent in front (but no lever)
b) some neighbours (in front) (but no neighbour behind or same rank)
c) < rank_5
to find out if a pawn is backward we look at the squares in front of this pawn to reach the same rank as the next neighbour.
In current master, a pawn is backward if any of those squares is controlled by an enemy pawn on an adjacent file
In this version, a pawn is ALSO backward if any of those squares is occupied by an enemy pawn.

Simplify popcnt
Also a speedup(about 1%) on 64-bit w/o hardware popcnt
Retire Max15 and Full template parameters
(Contributed by Marco Costalba)
Now that we have just SW and HW versions, use
template default parameter to get rid of explicit
template parameters.
Retire bitcount.h and move the only defined
function to bitboard.h
No functional change

32-bit/64-bit Makefile fix
Counter intuitively, make build ARCH=x86-32 does NOT produce a 32-bit compile
when running a 64-bit OS. Nor would ARCH=x86-64 produce a 64-bit compile when
running a 32-bit OS (assuming it compiled w/o errors).
No functional change
