mac_pdu: reset subheader state when deleting from PDU
...
when packing MAC PDUs, adding a new SDU might fail, for example
because RLC couldn't provide a new PDU. The muxer then needs
to delete the subheader from the PDU again.
When adding a padding BSR at the end, the same subheader is again
used to store the BSR, so any state in that subheader should be removed.
In the particular case, this was causing an issue when logging a LBSR
because the LCG buffer states are printed using the payload buffer,
which was still pointing to some memory that was used when trying
to add the new RLC PDU in the beginning.

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

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
