#282 Preset index table size and depth to prevent memory fragmentation

[Bernd Löhr]

In a multi-client environment, succesive calls to tlc_updateSession() can lead to memory fragmentation during the initialisation phase. To avoid this, memory for the index tables should be allocated beforehand based on the overall expected number of telegrams.
There are several ways to pass these additional configuration values to the stack:

1. Extending the memConfig struct given to tlc_init(); this would need minor modifications in the API, only.
2. An additional call tlc_configIndexTablesMem() with the maximum number of comIds for ingress/egress...
3. Compile-time specified for HIGH_PERF_INDEXED only

[Bernd Löhr]

Because indexing concerns telegram count , which is related to interfaces (app sessions), point 1. is not a good idea and point 3 is too static. Thus: An additional API call will be used.

Additional configuration call has been added:
TRDP_ERR_T tlc_presetIndexSession (
TRDP_APP_SESSION_T appHandle,
TRDP_IDX_TABLE_T *pIndexTableSizes);
