For a 'definition' query on X in p.X, use special logic to load and
parse package p and find the declaration of package member X, without
using the type checker. Such queries now typically take under
10ms (faster than godef).
The logic assumes that import "something/p" defines the name p. If this
assumption is false, p.X could be a selection of a field or method X on
a member p of the same package, defined in another file.
So don't write code like that.
Added missing test of 'definitions'.
JSON tests now sanitize absolute $GOPATH filenames in the output.

We define a derived mode of compilation-mode, so that various
names say "guru" instead of "compilation", and use the hooks it
provides to apply our postprocessing incrementally instead of
all at the end. It's much faster, and works nicely with the
new streaming referrers query.
Compilation mode requires a shell command, not an execve array,
so go-guru--compile-command joins the arguments with spaces.
go-guru--exec has been specialized for JSON mode,
and renamed to go-guru--json.
go-guru--set-scope-if-empty is now done by each mode, to avoid
the NEED-SCOPE parameter to go-guru--exec.

The new code in buildutil is an almost identical copy of the code in

- Instead of reading into a bytes.Buffer, we read directly into a []byte
of appropriate size
- sameFile first attempts a simple comparison of path.Clean'ed paths.

This CL makes little observable difference to the behavior but paves the
way for streaming 'referrers' and (later) 'implements' queries which
scan the entire workspace, but print each result as soon as it is found.
The go/loader package now exposes a hook, AfterTypeCheck, that lets
clients inspect each package as soon as it is type-checked, and also
modify it, for instance to release unneeded data structures.
A 'referrers' query applied to an exported object must scan the entire
workspace. It uses this hook so to gather uses of the query object in
streaming fashion. However, for now, it still accumulates the results
and prints them all at the end, though I propose to change that in a
follow-up.
Code details:
- The referrers logic had a 2-iteration loop to load first the query
package and then if necessary the enlarged program. The second
iteration has now been unrolled and split into globalReferrers.
- Queries for package names (whether in a package declaration or
a qualified identifier) have been split off into packageReferrers.
It now loads all direct importers of the query package,
which catches some references that were missing before.
(It used to inspect only the forward dependencies of the query
package.)
Also:
- Referrers.Pos (the position of query identifier) was removed from the
JSON output. It's a nuisance to compute now, and it's already
absent from the plain output.
(In a follow-up, I plan to simplify the information content of the
JSON output exactly what is currently printed in the plain output.)
