Allow GZIP compression of remote-bound WebRTC event logs Compress remote-bound WebRTC event logs while writing them to disk. * Logs for which the file size budget did not allow covering the entire call, can now get more coverage. * Short calls, for which we could log the entire call anyhow, benefit from a lower cost in bandwidth when the log is uploaded. Compression takes place incrementally over the duration of the call, avoiding a spike in resource utilization. The file-size limit is very strictly abided by. Before compression takes place, an estimation is made over whether the compressed string will fit in the file without exceeding the budget. If not, the file is terminated (as it would for the uncompressed version). In the unlikely case that the estimation is mistaken, and we've compressed to the point that writing to the file would make it exceed its allotted maximum size, the file is dicarded. (It is infeasible to write a compression footer at that point.)
