Alexander Couzens ccde5c9557 remove pcu own bitvector implementation
The osmocore bitvec is exact the same, but use a pointer instead of
a reference.

aravind sirsikar c0c3afd079 Handle Immediate assignment reject
When RACH is received, PCU will generate the Immediate assignment reject
message if no resources are present. The encoding is done based on section
9.1.20 of 44.018 version 11.7.0 Release 11. This patch also includes the
test case to validate the generated Immediate assignment reject message.

This patch is integration tested on Osmo-trx setup with Ettus B210 board
and LG F70 MS with some simulation code changes in Osmo-pcu.

Aravind Sirsikar 7c7a86c080 Fix GPRS PUAN encoding: wrong BSN status
Earlier there was an incorrect encoding of BSN status in GPRS PUAN message.
This was a bottle neck for GPRS performance testing for UL. Which has been fixed
in this patch.

Aravind Sirsikar a35c911a91 GPRS: PUAN encoding: add test case to show wrong BSNs status
This patch adds a test case which expects a current bug with
GPRS PUAN encoding. The test's expectation
is corrected along with the bug fix in a subsequent commit

Jacob Erlbeck 419b034975 tbf: Use bitvec based window methods for GPRS
Currently the old fixed 64 bit RBB based implementation is used for
GPRS.

Use the new bitvec based methods instead.

Jacob Erlbeck a3a567e765 rlc: Add constructor to window classes
Currently the gprs_rlc_dl_window and gprs_rlc_ul_window do not have
constructors, but need to get initialized explicitly.

This commit adds constructors to both classes and removes explicit
external initialization code.

Jacob Erlbeck d87e1d6ab7 rlc: Do not raise_v_q in receive_bsn
Currently gprs_rlc_ul_window::receive_bsn calls raise_v_q and returns
the number of RLC data blocks that can be taken from the queue. This
does not fit the EGPRS feature to put 2 independant data blocks in a
single RLC block.

This commit removes raise_v_q from receive_bsn, hence it must be
called explicitely to get the number of processable data blocks.

Jacob Erlbeck 1f33294b1c pcu: Fix non-critical warnings
These fixes do not affect the semantics of the code. They either help
gcc by providing default values that won't be used ("may be
uninitialised"), remove unused variables, or change signed to
unsigned variables to avoid comparison warnings.

move_window(), state(), count_unacked() out of v_b directly into the UL
window and provide a function get_state in v_b to access the v_b
elements.

* Make append_data, remaining_space and fits_in_current.. work
  on m_length and not the index. This ways things can't overflow.
* The current API consumer was moving the m_index so it should have
  worked okay.
