History
nickpellingandStéphane Nicolet d232a4ae68 Clarify the mapping of files to queenside 
This patch replaces the obscure expressions mapping files ABCDEFGH to ABCDDCBA
by explicite calls to an auxiliary function:

  old:   f = min(f, ~f)
  new:   f = map_to_queenside(f)

We used the Golbolt web site (https://godbolt.org) to check that the current
code for the auxiliary function is optimal.

STC:
LLR: 2.96 (-2.94,2.94) [-3.00,1.00]

Achieved with a bit of help from Sopel97, snicolet and vondele, thanks everyone!
