/* Thread local storage.
A minimal wrapper that should be implementable across many compilers,
and implementable efficiently across most modern compilers.
Thread locals have type intptr_t.
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. */
