Convert some more things to size_t.

Browse Source 
These changes stem from requests by Andrew on https://codereview.webrtc.org/1228823002/ to eliminate some "return -1"s and change to using asserts plus returning size_ts.  I then also converted the relevant connected bits.

This also cleans up a bunch of style issues, e.g. no spaces around operators.
