SECHashObjects[] is no longer exported. New function HASH_GetHashObject returns pointer to selected const object. SSL statistics are now in a structure whose address is obtained via a call to SSL_GetStatistics(). On NT, the new symbol NSS_USE_STATIC_LIBS must be declared in programs that use the static SSL library. Also, propagate "const" declaration for SECHashObjects. git-svn-id: svn://10.0.0.236/trunk@84403 18797224-902f-48f8-a5cc-f745e15eee43
