Custom string handling code enabled by OptJr macro removed from implementation of strings in TCollection and elsewhere. Functions from string.h are used instead of macros from Standard_String.hxx File Standard_String.hxx and methods ISSIMILAR and HASHCODE of TCollection*String classes are removed (to be replaced by strcasecmp). Functions HashCode for strings reimplemented using DJB2 algorithm for C strings and SDBM algorithm for extended strings. Adding test cases and draw-command for issue CR11758 Fix misprint added with previous integration Fix misprint in the test command. Remove compilation warnings (Linux). Avoid compiler warning "dereferencing type-punned pointer will break strict-aliasing rules" on Linux
