[PATCH v2 00/25] testing and plugin updates

[Alex Bennée]

Here is the usual accumulation of testing patches along with some
updates for TCG plugins. Aside from a few more tricks for some of the
plugins I've also fixed a bug and done some tidying up of the gcov
behaviour. Since v1 I've fix a build issue with FreeBSD and
incorporated some more testing patches from the list as well as
addressed comments. As usual individual updates are mentioned bellow
the --- in the individual patches.

I am seeing some failures on gitlab CI but it's hard to pin down if it
is due to gitlab stability or something in this series. I'm posting
now for review so as not to hold that up while I poke some more. I'm
also open to any ideas for how to replicate.

 - plugins: move reset of plugin data to tb_start
 - tests/plugins: add instruction matching to libinsn.so
 - tests/plugin: allow libinsn.so per-CPU counts
 - block: fix FreeBSD build failure with fallocate
 - Makefile: also remove .gcno files when cleaning
 - tests/qtest: enable more vhost-user tests by default
