* cmd/dlv,debugger: Improve dlv trace and trace command output This patch improves the `dlv trace` subcommand output by reducing the noise that is generated and providing clearer more concise information. Also adds new tests closing a gap in our testing (we previously never really tested this subcommand). This patch also fixes the `dlv trace` REPL command to behave like the subcommand in certain situations. If the tracepoint is for a function, we now show function arguements and return values properly. Also makes the overall output of the trace subcommand clearer. Fixes #2027

dlv trace
Compile and begin tracing program.
Synopsis
Trace program execution.
The trace sub command will set a tracepoint on every function matching the provided regular expression and output information when tracepoint is hit. This is useful if you do not want to begin an entire debug session, but merely want to know what functions your process is executing.
The output of the trace sub command is printed to stderr, so if you would like to only see the output of the trace operations you can redirect stdout.
