perf symbols: Rename kthreads to kmaps, using another abstraction for it
Using a struct thread instance just to hold the kernel space maps
(vmlinux + modules) is overkill and confuses people trying to
understand the perf symbols abstractions.
The kernel maps are really present in all threads, i.e. the kernel
is a library, not a separate thread.
So introduce the 'map_groups' abstraction and use it for the kernel
maps, now in the kmaps global variable.
It, in turn, will move, together with the threads list to the
perf_file abstraction, so that we can support multiple perf_file
instances, needed by perf diff.
