    Hide internal symbols and set hidden visibility · 858b47d2

    Set an explicit visibility of hidden for all internal functions at
    compile time if gcc is used to permit better optimization.  Hide all
    functions except the official interfaces using a version script on
    Linux.  This protects against leaking symbols into the application
    namespace and provides some mild optimization benefit.
