edge: Fix RLC message size
Currently the RLC message length that is obtained from the DSP is reduced by 1 if the last byte of the buffer includes spare bits. While this worked well with GPRS, these bits are being used to encode RLC blocks in EGPRS mode. Thus this last byte must not be chopped off. The functionality of the code is not affected by this, since the modified length value is not used. This commit adds GprsCodingScheme::usedSizeDL/UL to return the number of bytes needed to encode the message block. If there are single bits at the end that are to be used (EGPRS), the functions return the number of full bytes plus 1 (which is the buffer size reported by the DSP and returned by sizeUL/sizeDL). The commit also removes the len parameter from rcv_data_block_acknowledged. Sponsored-by: On-Waves ehf
