/* Thread local storage.

   A minimal wrapper that should be implementable across many compilers,
   and implementable efficiently across most modern compilers.

   Thread locals have type gpr_intptr.

   Declaring a thread local variable 'foo':
     GPR_TLS_DECL(foo);
   Thread locals always have static scope.

   Initializing a thread local (must be done at library initialization 
   time):
     gpr_tls_init(&foo);

   Destroying a thread local:
     gpr_tls_destroy(&foo);

   Setting a thread local (returns new_value):
     gpr_tls_set(&foo, new_value);

   Accessing a thread local:
     current_value = gpr_tls_get(&foo, value); 

   ALL functions here may be implemented as macros. */
