Andre Puschmann 9dd02af15c network_utils: lower verbosity of when socket connection fails
the network helper can log this event but it should be up to
the caller to decide whether this is an error or not.

Andre Puschmann 6dc7841369 epoll_helper: move code to block OS signals into own helper function
before epoll can handle signals, the calling thread needs to block
them. the blocking needs to happen before any other threads get
spawned so they inherit the mask.

Andre Puschmann 6a56476b2a rlc: increase RLC Tx SDU queue
the Tx SDU has been set to 128 PDUs because this gives approx.
150kByte UL buffer state (max value for Rel 8 BSR).

Previously, however, we've always reported too much pending UL
data because we weren't subtracting the transmitted data from
the reported data.

with this newer BSR reporting, however, even with full buffers we would
never report full buffers because the queues size is too short.

This seems to cause issues for iperf TCP sessions not resulting
in full DL rate, see isse #1703. It seems that the TCP bandwitdh
probing works better with larger buffers (in our case this can
only be achieved with more PDUs in the pool).

This should fix #1703

Andre Puschmann d48bc8837e pdu: refactor MAC PDU class
this patch refactors the MAC PDU class, the main changes are:

* add to_string() method to pretty print PDU and subheaders
  This allows to have a single log entry per MAC PDU with all its
  contents.
  It removes the C-style fprint() method

* Simplity payload vs. w_payload_ce
  Before we've used payload when reading the PDU and w_payload_ce
  as a buffer when writing. In all getters we needed to differentiate
  between both. Now payload points to w_payload_ce initially and is
  only updated when parsing a new PDU.

* add various helpers, e.g. to get subheader index, update a BSR, ..

* fix PDU test to use new to_string() method
