Pull tracing tools updates from Steven Rostedt

- This is mostly just consolidating code between osnoise/timerlat and
top/hist for easier maintenance and less future divergence

tools/rtla: Consolidate code between osnoise/timerlat and hist/top

Currently a lot of code is duplicated between the different rtla tools,
making maintenance more difficult, and encouraging divergence such as
features that are only implemented for certain tools even though they
could be more broadly applicable.

Merge the various main() functions into a common run_tool() with an ops
struct for tool-specific details.

Implement enough support for actions on osnoise to not need to keep the
old params->trace_output path.

tools/rtla: Create common_apply_config()

Merge the common bits of osnoise_apply_config() and
timerlat_apply_config(). Put the result in a new common.c, and move
enough things to common.h so that common.c does not need to include
osnoise.h.

tools/rtla: Move top/hist params into common struct

The hist members were very similar between timerlat and top, so
just use one common hist struct.

output_divisor, quiet, and pretty printing are pretty generic
concepts that can go in the main struct even if not every
specific tool (currently) uses them.
