/** Synchronization primitives for GPR.

   The type  gpr_mu              provides a non-reentrant mutex (lock).

   The type  gpr_cv              provides a condition variable.

   The type  gpr_once            provides for one-time initialization.

   The type gpr_event            provides one-time-setting, reading, and
                                 waiting of a void*, with memory barriers.

   The type gpr_refcount         provides an object reference counter,
                                 with memory barriers suitable to control
                                 object lifetimes.

   The type gpr_stats_counter    provides an atomic statistics counter. It
                                 provides no memory barriers.
