Changes in version 1.2.0:

* Realtime interface changes:
  - Re-introduced ecrt_domain_queue() to allow datagram queuing apart
    from datagram processing. The queuing of a domain's datagrams is not
    done in ecrt_domain_process() any more!
  - Removed ecrt_master_deactivate(). Its functionality was moved into
    ecrt_master_release().
  - Removed ecrt_master_prepare(). Its functionality was moved into
    ecrt_master_activate().
  - Renamed ecdev_start() and ecdev_stop() to ecdev_open() and ecdev_close().
    These two functions now take a pointer to ec_device_t as their arguments.
  - The data_ptr parameter of ecrt_domain_register_pdo(),
    ecrt_domain_register_pdo_list() and ecrt_domain_register_pdo_range() may
    not be NULL any more.
  - Removed ecrt_slave_pdo_size(). This function was deprecated long before.
  - Introduced ECRT_VERSION_MAGIC macro and ecrt_version_magic() function.
* Device interface changes:
  - ec_isr_t was replaced by ec_pollfunc_t, the device driver has to supply
    a poll function to call its ISR. This was introduced because some network
    drivers' interrupt functions have different arguments.
* State machines now try to re-send datagrams on datagram timeout.
* New option -c of the lsec script, displays slave current consumptions and
  remaining current.
* Added frame counter in master info file.

Changes in version 1.1.1:

* State change FSM: Clearing of sync managers before PREOP.
* Added modules_install make target.
* Device modules for kernel 2.6.17.
* SDO configurations available in Sysfs.
* FMMU configurations cleared when going to INIT.
* Slave-specific logs only at debug level 1 (for large busses).
* Slave flags (error, online) available in Sysfs.
* Acknowledging of spontaneous state changes in master FSMs.
* ecrt_master_deactivate() deprecated.
* Persistent slave lists. Slave structures are only regenerated on topology
  change in IDLE mode.
* SDO reading via Sysfs.
* Added ecrt_domain_register_pdo_range()
* Fetching of SDO dictionary.
* Better timing behaviour when starting up under high CPU load.
* Applied Autotools.
* Improved output of lsec.
* SDO download state machine.
