QUIC: added support for segmentation offloading.

To improve output performance, UDP segmentation offloading is used
if available.  If there is a significant amount of data in an output
queue and path is verified, QUIC packets are not sent one-by-one,
but instead are collected in a buffer, which is then passed to kernel
in a single sendmsg call, using UDP GSO.  Such method greatly decreases
number of system calls and thus system load.
