Add operation state 'enabled' and 'local calls' into Terms

[RolfRabenseifner]

Problem

The definition of "MPI operation" concentrates on what happens within one process. This issue defines the relation between related operations in one ore more processes, like the relation between a send and a receive operation, or the relation between the individual operations generated by a collective call issued on all processes belonging to one communicator.

A related problem is MPI procedure calls can have different behavior under some constraints. For example athe invocation of MPI_RECV is local if the corresponding MPI_SEND is already started.

Proposal

Defines a new state: "enabled". In addition, the definition of "local and nonlocal procedures" are explicitely extended for the use of the definition under constraints or for a specific invocation of an MPI procedure.

Due to the many changes during the two weeks before and during the Feb 1+8, 2023 meeting (reflected by the failed no-no), a new reading is required at the March 2003 meeting.
