machine->guests and threads->entries.
The conversion is straightforward, however, it's worth noticing that the
rb_erase_init() calls have been replaced by rb_erase_cached() which has
no _init() flavor, however, the node is explicitly cleared next anyway,
which was redundant until now.

There we don't need rbtree, only in comm.c, also ditch perf.h, not
needed at all.

There we need just forward declarations, so remove it and add it just on
the .c files that actually touch the struct definitions.

And fixup the fallout in places like annotation and jitdump that were
using things like dirname() but weren't including libgen.h, etc.

Some are being obtained indirectly and as we prune unnecessary includes,
this stops working, fix it by adding the headers for things used in
these file.

We already have it, move those there from events.h so that we untangle
the header dependencies a bit more.

to access symbol_conf in another header, such as annotate.h.
