lock io_mutex when unqueueing datagrams; unqueue datagrams from send-receive queue.

Minor changes (consistent variable naming)

Datagram queue race fixed: insert datagrams into master-fsm_queue with fsm_queue list_head

Optionally compile with trace_printk support

properly deactivate slaves if there is no eoe slave

always use rt_mutex instead of semaphore for mutual exclusion on kernels >= 2.6.24 (removed --enable-mutex build option)

releasing of refcounted requests fixed: do not call EC_SLAVE_DBG without valid slave

e1000 on 2.6.33: handle link-down

SoE request wait_event() deadlock fixed: use wait_event_interruptible and refcount ec_master_soe_request_t objects with kref

Register read/write wait_event() deadlock fixed: use wait_event_interruptible and refcount ec_reg_request_t objects with kref

Sii write wait_event() deadlock fixed: use wait_event_interruptible and refcount ec_master_sii_write_request_t objects with kref

FoE wait_event() deadlock fixed: refcount ec_master_foe_request_t objects with kref

use rt_mutex instead of semaphore for mutual exclusion (use --enable-mutex)

SDO wait_event() deadlock fixed: refcount ec_master_sdo_request_t objects with kref

Failed FoE transfer: notify foe_queue instead of sdo_queue

fixed warning due to 64bit size_t

ecrt_master_callbacks: replaced send/receive callback mechanism with locking mechanism; removed ecrt_master_send_ext

fixed 'ethercat eoe' command: interchanged rx/tx bytes/rates

renamed ext_injection_timeout -> fsm_injection_timeout

removed now obsolete ext_datagram_queu

removed eoe thread: eoe processing now done by Idle/Operation thread

use ext_queue_sem for fsm datagram queue (instead of io_sem)

replaced injection_seq mechanism with fsm datagram queue

Increment injection_seq on slave state changes

ec_master_queue_external_datagram: fixed missing up(io_sem)

merge

Be more tolerant when selecting slaves and domains.

Fixed / improved config selection.

Assume increasing ranges if second number is omitted.

merge.

Implemented ranges for slaves, configs and domains.

Added ecrt_master_reset() method.

Inplace I/O bug: correct domain tx-size when tx-size of input and output fmmu is different.

fixed compiling without EC_HAVE_CYCLES (dc_jiffies_app_start_time)

Minor 64bit improvements (use %zu when formatting size_t values in printk)

fixed ioctl codes, increased ioctl version magic

Merged

Re-enabled waiting for clock synchronity before setting dc offsets. (changeset b0dcdfbd4238)

fixed race when calculating DC offsets and start times due to ec_slave_config_attach: removed obsolete request to change slave state to OP.
The request to change to OP is done by ec_master_request_op after activating the master.

renamed dc_cycles_app_time -> dc_cycles_app_start_time & dc_jiffies_app_time -> dc_jiffies_app_start_time

Idle thread considers fsm step prepared by Op-thread (Otherwise some state changes may get lost)

use app_start_time for initial DC offset calculation because app_time might be overwritten while calculating the offsets.

Use ESC port order (0-3-1-2) for bus topology and DC delay calculation

Fixed copying port information.

Insert port information into slave info.

Inplace I/O: let input Pdos use the same bus space as Output Pdos
