This change refactors the cmd/trace package and adds most of the support for v2 traces. The following features of note are missing in this CL and will be implemented in follow-up CLs: - The focustask filter for the trace viewer - The taskid filter for the trace viewer - The goid filter for the trace viewer - Pprof profiles - The MMU graph - The goroutine analysis pages - The task analysis pages - The region analysis pages This CL makes one notable change to the trace CLI: it makes the -d flag accept an integer to set the debug mode. For old traces -d != 0 works just like -d. For new traces -d=1 means the high-level events and -d=2 means the low-level events. Thanks to Felix Geisendörfer (felix.geisendoerfer@datadoghq.com) for doing a lot of work on this CL; I picked this up from him and got a massive headstart as a result. For #60773. For #63960.
