Add a new socket option SO_TS_CLOCK to pick from several different clock
sources to return timestamps when SO_TIMESTAMP is enabled. Two additional
clock sources are:

o nanosecond resolution realtime clock (equivalent of CLOCK_REALTIME);
o nanosecond resolution monotonic clock (equivalent of CLOCK_MONOTONIC).

In addition to this, this option provides unified interface to get bintime
(equivalent of using SO_BINTIME), except it also supported with IPv6 where
SO_BINTIME has never been supported. The long term plan is to depreciate
SO_BINTIME and move everything to using SO_TS_CLOCK.

Idea for this enhancement has been briefly discussed on the Net session
during dev summit in Ottawa last June and the general input was positive.

This change is believed to benefit network benchmarks/profiling as well
as other scenarios where precise time of arrival measurement is necessary.

There are two regression test cases as part of this commit: one extends unix
domain test code (unix_cmsg) to test new SCM_XXX types and another one
implementis totally new test case which exchanges UDP packets between two
processes using both conventional methods (i.e. calling clock_gettime(2)
before recv(2) and after send(2)), as well as using setsockopt()+recv() in
receive path. The resulting delays are checked for sanity for all supported
clock types.

Refactor the regression test code by splitting huge monolithic C
file into smaller pieces that are hopefully easier to understand
and extend. This is to pave the ground for adding few more
socket timestamp formats that I am working on here.

No functional changes (I hope).

Don't run the t_cmsg_len testcase on 64-bit architectures

It always fails when trying to send through the sendit(9) private KPI in the
kernel due to a size mismatch between the msghdr and data being sent [*], which
suspiciously seems like it's related to sizeof pointers instead of scalars, or
something of that ilk

Major update for unix_cmsg from Andrey Simonenko.

Quoting the submitter:
- Added tests for SCM_BINTIME, LOCAL_PEERCRED, cmsghdr.cmsg_len
- Code that checks correctness of groups was corrected (getgroups(2) change)
- unix_cmsg.c was completely redesigned and simplified
- Use less timeout value in unix_cmsg.c for faster work
- Added support for not sending data in a message, not sending data and
data array associated with a cmsghdr structure in a message
- Existent tests were improved
- unix_cmsg.t was redesigned and simplified

Correctness of unix_cmsg verified on 7.1-STABLE, 9.1-STABLE and 10-CURRENT.
