Subject: Move piece values in piece.h / piece.cpp
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=df4b106716f0fb0a5f5887b1cffeb544174008f7

Move piece values in piece.h / piece.cpp

Where they belong.

Note that array PieceValueMidgame[] and PieceValueEndgame[]
are now declared extern in the header and moved in piece.cpp
so to avoid allocate the array each time the header is
included !

No functional change.
