perf session: Move all state items to reader object

Browse source

We need all the state info about reader in separate object to load data
from multiple files, so we can keep multiple readers at the same time.
Moving all items that need to be kept from reader__process_events to
the reader object. Introducing mmap_cur to keep current mapping.
