70f0e2472d go.tools/oracle: consider calls to close a peer operation.
This makes it possible to find corresponding closes to receives and sends.

8b9d1fd507 go.tools/oracle: implements: now shows whole-program implements relation for selected type.
(Previously it showed the implements relation for all types within the query package.)

f119874203 go.tools/oracle: improvements to command set and performance.
Command set:
- what: an extremely fast query that parses a single
  file and returns the AST stack, package name and the
  set of query modes that apply to the current selection.
  Intended for GUI tools that need to grey out UI elements.
- definition: shows the definition of an identifier.
- pointsto: the PTA features of 'describe' have been split
  out into their own command.
- describe: with PTA stripped out, the cost is now bounded by
  type checking.

Performance:
- The importer.Config.TypeCheckFuncBodies predicate supports
  setting the 'IgnoreFuncBodies' typechecker flag on a
  per-package basis.  This means we can load dependencies from
  source more quickly if we only need exported types.
  (We avoid gcimport data because it may be absent or stale.)
  This also means we can run type-based queries on packages
  that aren't part of the pointer analysis scope. (Yay.)
- Modes that require only type analysis of the query package
  run a "what" query first, and restrict their analysis scope
  to just that package and its dependencies (sans func
  bodies), making them much faster.
- We call newOracle not oracle.New in Query, so that the
  'needs' bitset isn't ignored (oops!).  This makes the
  non-PTA queries faster.

Also:
- removed vestigial timers junk.
- pos.go: existing position utilties split out into own file.
  Added parsePosFlag utility.
- numerous cosmetic tweaks.

+ very basic tests.

To do in follow-ups:
- sophisticated editor integration of "what".
- better tests.
- refactoring of control flow as described in comment.
- changes to "implements", "describe" commands.
- update design doc + user manual.

37f76edde8 go.tools/oracle: support -format=xml (for Eclipse)
This CL is mostly a renaming s/json/serial/, abstracting the
oracle package away from any particular data syntax.  (The
encoding/* machinery is very clean; clearly I should have
structured it this way from the outset.)

Supporting XML then becomes a one-liner in cmd/oracle/main.go.

Also: call MarshalIndent(), not Marshall() then Indent().
