- Removed ecrt_master_get_slave_by_pos(), because it is no longer

- Added ec_slave_config_state_t for the new method

- Process data memory for a domain can now be allocated externally. This
offers the possibility to use a shared-memory-region. Therefore,
added the domain methods ecrt_domain_size() and ecrt_domain_memory().

* Pdo configuration is now supported.
* Current Pdo mapping/configuration is now read during bus scan, without
using the Sdo dictionary.
* Current Pdo mapping/configuration is now read via CoE during bus scan, using
direct Sdo access, independent of the dictionary.
