libtorrent has a relatively heavy headers, that take lots of time to process. This commit removes unnecessary includes of libtorrent headers and replaces them with forward declarations. I had to move some functions in QBtSession from slots to regular functions because moc'ed file want to see complete types of all parameters of slots. "time make" of full rebuild before this series of commits: real 13m35.937s user 12m1.295s sys 1m25.908s after: real 10m54.390s user 9m31.167s sys 1m12.580s
