2023-07-03plugins: fix memory leak while parsing optionsAlex Bennée
It was hard to track down this leak as it was an internal allocation by glib and the backtraces did not give much away. The autofree was freeing the allocation with g_free() but not taking care of the individual strings. They should have been freed with g_strfreev() instead. Searching the glib source code for the correct string free function led to: G_DEFINE_AUTO_CLEANUP_FREE_FUNC(GStrv, g_strfreev, NULL) and indeed if you read to the bottom of the documentation page you will find: typedef gchar** GStrv; A typedef alias for gchar**. This is mostly useful when used together with g_auto(). So fix up all the g_autofree g_strsplit case that smugly thought they had de-allocation covered.

2020-07-15plugins: expand the bb plugin to be thread safe and track per-cpuAlex Bennée
While there isn't any easy way to make the inline counts thread safe we can ensure the callback based ones are. While we are at it we can reduce introduce a new option ("idle") to dump a report of the current bb and insn count each time a vCPU enters the idle state.

2019-11-12tcg plugins: expose an API version conceptAlex Bennée
This is a very simple versioning API which allows the plugin infrastructure to check the API a plugin was built against. We also expose a min/cur API version to the plugin via the info block in case it wants to avoid using old deprecated APIs in the future.
