Make TCP read timeouts configurable.
This should be helpful on high-latency networks, like Tor or I2P.
Also gofmt.

rearrange tcp reading loop
2018-07-19 18:18:51 -05:00
cathugger
91a374d698 rearrange tcp reading loop
according to documentation of io.Reader interface,
"Callers should always process the n > 0 bytes returned before considering the error err. Doing so correctly handles I/O errors that happen after reading some bytes and also both of the allowed EOF behaviors."
