// 1) initialized with default values at startup.
// 2) overriden during compilation of MemProf runtime by providing
//    compile definition MEMPROF_DEFAULT_OPTIONS.
// 3) overriden from string returned by user-specified function
//    __memprof_default_options().
// 4) overriden from env variable MEMPROF_OPTIONS.
