/** Initialize theprogram pool */
/** Trace Restrict Data Storage Model Notes:
*
* Signals may have 0, 1 or 2 trace restrict programs attached to them,
* up to one for each track. Two-way signals share the same program.
*
* The mapping between signals and programs is defined in terms of
* TraceRestrictRefId to TraceRestrictProgramID,
* where TraceRestrictRefId is formed of the tile index and track,
* and TraceRestrictProgramID is an index into the program pool.
*
* If one or more mappings exist for a given signal tile, bit 12 of M3 will be set to 1.
* This is updated whenever mappings are added/removed for that tile. This is to avoid
* needing to do a mapping lookup for the common case where there is no trace restrict
* program mapping for the given tile.
*
* Programs in the program pool are refcounted based on the number of mappings which exist.
* When this falls to 0, the program is deleted from the pool.
* If a program has a refcount greater than 1, it is a shared program.
*
* In all cases, an empty program is evaluated the same as the absence of a program.
* Therefore it is not necessary to store mappings to empty unshared programs.
* Any editing action which would otherwise result in a mapping to an empty program
* which has no other references, instead removes the mapping.
* This is not done for shared programs as this would delete the shared aspect whenever
* the program became empty.
*
* Empty programs with a refcount of 1 may still exist due to the edge case where:
* 1: There is an empty program with refcount 2
* 2: One of the two mappings is deleted
* Finding the other mapping would entail a linear search of the mappings, and there is little
* to be gained by doing so.
