rpc: fix data race in timeoutconn - `timeoutconn` handles state, yet calls to Read/Write make a copy of that state (non-pointer receiver) so any outbound calls will not have the state updated - Even without the copy issue, the renew methods can in edge cases set a new deadline _after_ DisableTimeouts have been called, consider the following racy behavior: 1. `renewReadDeadline` is called, checks `renewDeadlinesDisabled` (not disabled) 2. `DisableTimeouts` is called, sets `renewDeadlinesDisabled` 3. `DisableTimeouts` invokes `c.SetDeadline` 4. `renewReadDeadline` invokes `c.SetReadDeadline` To fix the above, the `Conn` receiver was made to be a pointer everywhere and access to renewDeadlinesDisabled is now guarded by an RWMutex instead of using atomics. closes #415 2021-01-24 14:53:59 +01:00			`func (c *Conn) readv(buffers net.Buffers) (n int64, err error) {`
