several APIs have been annotated with GCC 'access' attribute. This
should help GCC 10 issue better warnings.
* On Linux, functions the pthread_attr_setsigmask_np and
pthread_attr_getsigmask_np have been added. They allow applications
to specify the signal mask of a thread created with pthread_create.
Deprecated and removed features, and other changes affecting compatibility:
* The deprecated <sys/sysctl.h> header and the sysctl function have been
