lazarus-ccr/components/fpspreadsheet/source/crypto/3rdParty/fcl-hash

These files are copies from the FCL sources of FPC 3.3+ so that 
laz_fpspreadsheet_crypto can be compiled with older FPC versions.

Note: the files were renamed to prefix "fps" rather than "fp" so that the 
original FCL units can be used automatically if FPC version is v3.3 or newer.
