Subject: [PATCH v2 04/27] perf tool: Move fill defaults into tool.c
The aim here is to eventually make perf_tool__fill_defaults an init
function so that the tools struct is more const.
Create a tool.c to go along with tool.h. Move perf_tool__fill_defaults
out of session.c into tool.c along with the default stub values. Add
perf_tool__compressed_is_stub for a test in
perf_session__process_user_event.
perf_session__process_compressed_event is only used from being default
initialized so migrate into tool.c.
