edge: Make window size configurable
Currently the window size is fixed to 64 even for EGPRS. Support dynamic window sizes depending on the number of PDCH. The WS can be set to b + f * N_PDCH. If the result is not valid according to TS 44.060, Table 9.1.9.2.1, the value will be corrected to use the next lower valid value (or 64). The following VTY commands are added (config-pcu node): window-size <0-1024> set base (b) value and leave f unchanged window-size <0-1024> <0-256> set base (b) and factor (f) Sponsored-by: On-Waves ehf
