The old ioutil references are still valid, but update our code
to reflect best practices and get used to the new locations.
Code compiled with the bootstrap toolchain
(cmd/asm, cmd/dist, cmd/compile, debug/elf)
must remain Go 1.4-compatible and is excluded.
Also excluded vendored code.
For #41190.

The ViewerEvent, ViewerData and ViewerFrame structs are moved into
cmd/internal/traceviewer, and renamed Event, Data, and Frame.
The structs are the same, except for the following: A definition
for the JSON "bp" field that's defined in the trace format, but
missing in the structs has been added. Also, the Tid and Pid fields
on Event have been renamed TID and PID to better match Go style.
Finally, the footer field on ViewerData, which hasn't been used
for a while, has been removed.
This CL is in preparation for the usage of these structs by cmd/go's
tracing functionality.
Updates #38714

The performance improvement is not as big as we hoped.
Until the API is feature complete, we postpone the release
and avoid added complexity.
This change was prepared by reverting all the changes affected
src/cmd/trace and src/internal/traceparser packages after
golang.org/cl/137635, and then bringing back MMU computation
APIs (originally in src/internal/traceparser) to the
src/internal/trace package.
Revert "cmd/trace: use new traceparser to parse the raw trace files"
This reverts https://golang.org/cl/145457
(commit 08816cb8d7ed16b9c804587ff02c1ad1c3af6cd5).
Revert "internal/traceparser: provide parser that uses less space and parses segments of runtime trace files"
This reverts https://golang.org/cl/137635
(commit daaf361f74c3665bcb364356c5a9dd9f536c78c3).

golang.org/cl/81315 attempted to distinguish system goroutines
by examining the function name in the goroutine stack. It assumes that
the information would be available when GoSysBlock or GoInSyscall
events are processed, but it turned out the stack information is
set too late (when the goroutine gets a chance to run).
This change initializes the goroutine information entry when
processing GoCreate event which should be one of the very first
events for the every goroutine in trace.
Fixes #22574
