misc/trace: add license for the trace-viewer The trace-viewer doesn't use the Go license, so it makes sense to include the license text into the README.md file. While we're at here, reformat existing text using real Markdown syntax.

This directory contains helper file for trace viewer (`go tool trace`).
cmd/trace: add new command Trace command allows to visualize and analyze traces. Run as: $ go tool trace binary trace.file The commands opens web browser with the main page, which contains links for trace visualization, blocking profiler, network IO profiler and per-goroutine traces. Also move trace parser from runtime/pprof/trace_parser_test.go to internal/trace/parser.go, so that it can be shared between tests and the command.
