Type: refactor
This patch refactors the offload flags in vlib_buffer_t.
There are two main reasons behind this refactoring.
First, offload flags are insufficient to represent outer
and inner headers offloads. Second, room for these flags
in first cacheline of vlib_buffer_t is also limited.
This patch introduces a generic offload flag in first
cacheline. And detailed offload flags in 2nd cacheline
of the structure for performance optimization.

The check in listen state that the listener is not valid is not enough
if the time wait session's index overlaps an actual listener's index.
Thanks wanghanlin@corp.netease.com for the report!

On the one hand, make sure options are terminated with NOPs to avoid
issues with clients that can't parse options that don't end on an u32
boundary. On the other, make sure the padding is rfc compliant. If
options end with EOL the padding should be zeros. The current change
does not use EOL so the padding is NOPs.

Fifo chunk ooo lookup data structures are private (not allocated on
segment heap) and should only be initialized by transport protocols that
require out-of-order enqueues/dequeues (like tcp).

- switch to using vlib_time as reference for timestamps
- use us precision ticks for tcp but keep using ms precision for
timestamps. As a result, srtt, rttvar and rto are now measured in us
instead of ms. MRTT samples from timestamps are converted from ms to
us (not accurate under ms) while high precision samples are used with us
precision, i.e., they're no longer converted to ms precision samples.
