* wasnt showing error message for invalid arguments to slsmultireceiver
* allow 0 arguments to act like an slsReceiver with start tcp port 1954 and just 1 receiver
* changed rxr callback signatures to all include structs
* removed datamodify call back as size can be changed in the original data call back now
* bringing some parameters (set functions) to dataProcessor class for its callback (namely udpport, quad, fliprows, totalframes, jsonheader), resulting in also removing totalframes from 2 other function signatures
* updated MultiReceiverApp to reflect the new callback signatures
* gui message doesnt show if it has a '>' symbol in error msg
* minor refactoring for readability (size_t calc fifo size)
* refactoring listening udp socket code: activated and datastream dont create udp sockets anyway, rc<=- should be discarded in any case
* wip
* refactoring memory structure access
* wip: bugfix write header + data to binary

* test for rx_arping
* arping ip and interface from client interface
* apring thread added to thread ids
* clean code for thread for arping
* removing the assumption that udpip1 fill be updated along with udpip2
* review, replacing syscall(sys_gettid) with gettid()
