Vasil Velichkov dfcf7fd5a3 Print the error message on stderr in a python2 compatible way

Vasil Velichkov 9feb7da807 grgsm_decode: Print frequency or ARFCN message on stderr 
For some yet unknown reasons in travis on Debian testing and Kali rolling
the message gets printed after the burst and decode.sh and decrypt.sh
tests fails because of this.

Instead of filtering this messages in the tests I think it is better
such messages to be printed on the standard error output

Vasil Velichkov 46c90bec99 Various python3 related changes 
- Use relative import for grgsm's modules
- Convert map to list
- Remove the hier_block.py workaround as as gnuradio 3.7 is no longer
  supported in this branch

Vasil Velichkov c5bb436cda Fix the TCH/H decoder and demapper XML definitions 
- The second argument of tch_h_decoder constructor is a string that
  accepts the value of MultiRate configuration element and not an enum
  like the tch_f_decoder decoder.
- Make the demapper's burst sink required.
- Make all parameters visible.
- Rename the TCH/H Channel parameter to Sub-channel number.
- Add the qa_tch_h_decoder test in the CMakeLists.txt
- Fix several typos

Vasil Velichkov 7f259fdb68 Add TCH/H decoder block with AMR multirate support 
Add new TCHH channel mode
Add two new optional arguments

    -m CHAN_MODE, --mode=CHAN_MODE
                        Channel mode. Valid options are 'BCCH' (Non-combined
                        C0), 'BCCH_SDCCH4'(Combined C0), 'SDCCH8' (Stand-alone
                        control channel) 'TCHF' (Traffic Channel, Full rate),
                        'TCHH' (Traffic Channel, Half rate)

    --sub-channel=TCH_H_CHANNEL
                        TCH/H sub-channel. [default=0]
    --multi-rate=MULTI_RATE
                        The MultiRrate configuration element from the
                        Assigment Command message. Example: 28111a40. See 3GPP
                        TS 44.018 - 10.5.2.21aa MultiRate configuration

Example:
    grgsm_decode -m TCHH --sub-channel 0 --multi-rate 2811 -o voice.amr ...
