Currently, there's a limit of MAX_PORTS ports (8 by default). This patchset removes this limitation by using linked lists instead of fixed size arrays.
The core patches are 3/6 and 6/6, the rest are prerequisites: patch 1/6 is moving per-port fields from struct clock to individual ports in order not to have to maintain several linked lists, patch 2/6 moves the uds port from the port array, as having it a part of linked list would make the various checks for uds port unnecessary complicated, patch 5/6 replaces the port numbering that is based on array of interface names by a per clock counter. The remaining patch, 4/6, is a follow up optimization to 3/6. Changes in v5: rebased. Addressed Richard's comments (comment in clock_remove_port, calloc and cleanup of iface config). Changes in v4: rebased on top of the current git. Changes in v3: used the BSD implementation of LIST_FOREACH_SAFE, using the system one where available. Changes in v2: rebased on top of the current git, resolved warnings reported by Richard.
