Andre Puschmann dcb9004a71 zmq: refactor zmq argument parsing, allow zero indexing
It allows to provide an index for tx_port, rx_port, tx_freq and rx_freq even
for the first (and possibly only) port. So for example a MIMO config would be this for example:

tx_port0=tcp://*:2001,tx_port1=tcp://*:2003,rx_port0=tcp://localhost:2000,rx_port1=tcp://localhost:2002

Andre Puschmann 6cce22d6b8 add support for GPS-based sync to UE sync object 5 years ago
Andre Puschmann c7343cf6d8 protect sf_buffer from overrun in receive_samples
this patch adds a buffer len paramter to the receive_samples() call
that protects the (also) provided buffer from overflowing.

currently each call to srslte_ue_sync_zerocopy() which then calls receive_samples()
relies on a buffer that is "big enough". But that buffer is sometimes
2 subframes, sometimes 3 or 5, sometimes has space for the maximum PRB size, sometimes
only for 6 PRBs (i.e. during cell search).

By extending the interface to pass the buffer size we can make sure that
only samples are received that actually fit inside the provided buffer.
