    string: drop redundant declarations
    
    These standard functions shouldn't need custom declarations. The only
    case where redundancy might be needed is if there were inline functions
    there. But we don't have any here (anymore). Prune the per-arch headers
    of duplicate declarations while moving the asm/string.h inclusion past
    the declarations.
