Code coverage by individual VTCs

[Poul-Henning Kamp]

I have run GCOV on the individual VTC tests and chewed through
the results and produced two listings:

    http://phk.freebsd.dk/misc/vtcgcov_by_source_line.txt

	This listing shows source lines in varnish-cache, how many
	times they were executed running all the tests, and how
	many tests they were executed in.  If the last number is
	low, the tests are listed.

    http://phk.freebsd.dk/misc/vtcgcov_by_vtc.txt

	This listing shows the lowest number of VTCS which tested the
	source lines tested by each VTC.

	In other words, a value of one means that there are source
	lines in varnish-cache only tested by that VTC and a value
	of 258 probably means the VTC is not doing squat for us.

Please note that the tests were all run as root on FreeBSD 13-CURRENT,
so the results are not as comprehensive as they might look.
