ipc: add master socket number/path parameters

osmo-trx-ipc needs to know which master socket it should talk to, so
pass this path in the config device args like this:
dev-args ipc_msock=/path/to/socket

Additionally, add a master socket suffix number parameter to the ipc
backend,
ipc-driver-test -n 0 to start serving /tmp/ipc_sock0

- * viterbi_detector:
- *           This part does the detection of received sequnece.
- *           Employed algorithm is viterbi Maximum Likehood Sequence Estimation.
- *           At this moment it gives hard decisions on the output, but
- *           it was designed with soft decisions in mind.
- *
- * SYNTAX:   void viterbi_detector(
- *                                  const gr_complex * input, 
- *                                  unsigned int samples_num,

- *                                  float * output)
- *
- * INPUT:    input:       Complex received signal afted matched filtering.
- *           samples_num: Number of samples in the input table.
- *           rhh:         The autocorrelation of the estimated channel 
- *                        impulse response.
- *           start_state: Number of the start point. In GSM each burst 
- *                        starts with sequence of three bits (0,0,0) which 
- *                        indicates start point of the algorithm.
- *           stop_states: Table with numbers of possible stop states.
- *           stops_num:   Number of possible stop states
- *                     
- *
- * OUTPUT:   output:      Differentially decoded hard output of the algorithm: 
- *                        -1 for logical "0" and 1 for logical "1"
- *
- * SUB_FUNC: none
- *
- * TEST(S):  Tested with real world normal burst.

- * viterbi_detector:
- *           This part does the detection of received sequnece.
- *           Employed algorithm is viterbi Maximum Likehood Sequence Estimation.
- *           At this moment it gives hard decisions on the output, but
- *           it was designed with soft decisions in mind.
- *
- * SYNTAX:   void viterbi_detector(
- *                                  const gr_complex * input, 
- *                                  unsigned int samples_num, 
- *                                  gr_complex * rhh, 
- *                                  unsigned int start_state, 
- *                                  const unsigned int * stop_states, 
- *                                  unsigned int stops_num, 
- *                                  float * output)
- *
- * INPUT:    input:       Complex received signal afted matched filtering.
- *           samples_num: Number of samples in the input table.
- *           rhh:         The autocorrelation of the estimated channel 
- *                        impulse response.
- *           start_state: Number of the start point. In GSM each burst 
- *                        starts with sequence of three bits (0,0,0) which 
- *                        indicates start point of the algorithm.
- *           stop_states: Table with numbers of possible stop states.
- *           stops_num:   Number of possible stop states
- *                     
- *
- * OUTPUT:   output:      Differentially decoded hard output of the algorithm: 
- *                        -1 for logical "0" and 1 for logical "1"
- *
- * SUB_FUNC: none
- *
- * TEST(S):  Tested with real world normal burst.
