This is my follow up to my message here:
https://www.redhat.com/archives/libvir-list/2019-February/msg01213.html
This removes our custom ./configure --enable-test-coverage and
'make cov' targets in favor of gnulib's 'make coverage' which IMO
is much simpler to use. See the mail above for full explanation
Patch #2 adds some hacking.html docs, see that for some details
about gnulib's features here.

New subject: [libvirt] [PATCH 1/2] configure: Remove --enable-test-coverage
We provide a custom configure option --enable-test-coverage and
'make cov' target to generate code coverage reports. However gnulib
already provides a 'make coverage' which 'just works' and doesn't
require a special configure option.
This drops our custom implementation in favor of 'make coverage'.
Reports are now output to cov/index.html
