This code introduces **EXPERIMENTAL** support for NFs that can efficiently run on **shared** CPUs. NFs wait on semaphores when idle and are signaled by the manager when new packets arrive. Once the NF is in wake state, no additional notifications will be sent until it goes back to sleep. All code changes are featurized using INTERRUPT_SEM macro. See the ONVM README.md file for more information and warnings. Commit log: * merges rebased to master with sdnfv#147 * reverting num_clients update. * replace tabs with spaces * Readme describing experimental shared CPU support * Add usage and known limitations for shared CPU code
