The function has a bizarre signature: it was the only public function there
that exposed the reflect package. Also, its definition is peculiar and hard to
explain. It doesn't merit being exported.

This is an API change but really, it should never have been exported and
it's certain very few programs will depend on it: it's too weird.

Fixes #2846.

Be careful when printing line comments with incorrect
position information. Maintain additional state
impliedSemi: when set, a comment containing a newline
would imply a semicolon and thus placement must be
delayed.

Precompute state information pertaining to the next
comment for faster checks (the printer is marginally
faster now despite additional checks for each comment).

No effect on existing src, misc sources.

Also bring the names in doc.go in line with the source.
More radical resolutions are possible but require substantial internal
changes for very little benefit. Fixing it this way lets us keep the
embedding, which has a huge simplifying effect, and guarantees
binary compatibility.

Commands such as "dist version > VERSION" will cause
the shell to create an empty VERSION file and set dist's
stdout to its fd. dist in turn looks at VERSION and uses
its content if available, which is empty at this point.

Fix that by ignoring VERSION if it's empty.

Also prevent cmdversion from running findgoversion a
second time. It was already loaded by init.

Right now, GOTRACEBACK=0 means do not show any stack traces.
Unset means the default behavior (declutter by hiding runtime routines).

This CL makes GOTRACEBACK=2 mean include the runtime routines.
It avoids having to recompile the runtime when you want to see
the runtime in the tracebacks.
