Rename some trace functions

This patch renames a few trace-related functions, so that they adhere to
the de facto standard of naming command entry point functions
<command>_command.  I like the ease of looking up a command entry point
if they all follow that rule.

An enum label "tstop_command" conflicts with a new function name, so I
renamed this one trace_stop_command.

In v2:

- Rename functions of the trace_find family, as well as
  trace_dump_command.
