[CCID3]: Sending time: update to ktime_t and bug-fix
This updates the computation of t_nom and t_last_win_count to use the newer
gettimeofday interface.
The second point of this patch is to fix a bug in the send time processing:
ccid3_hc_tx_send_packet currently returns 0 when the time difference
between current time and t_nom is less than 1000 microseconds.
In this case the packet is sent immediately; but, unlike other packets
that can be emitted on first attempt, it will not have its window
counter updated and its options set as required. This is a bug.
Fix: Require the time difference to be at least 1000 microseconds. The
algorithm then converges: time differences > 1000 microseconds trigger the
timer in dccp_write_xmit; after timer expiry this function is tried again;
when the time difference is less than 1000, the packet will have its options
added and window counter updated as required.
I'm breaking this into two patches for you this time :-)
