The display of search results can now be changed. A slice of functions for displaying the results can now be provided. By default, three functions are provided to display documentation, source code, and textual results.
This makes it possible to replace them with equivalents that, say,
obtain search results from alternative source code search engines.

Anonymous field names are emitted as "" in the export data
since the actual name can be reconstructed easily from the
field's type name. But "" names are not exported names and
thus the respective qualified name emits complete package
information even if the actual field name is exported. Fix
the package upon import.

The package of a struct field is independent of the type of the
struct field - the old code was technically not correct. That said,
it does not seem possible (or very difficult) to create a test case
because for exported anonymous fields that field package doesn't matter
(it's not needed for name identity), and non-exported anonymous fields
cannot be accessed from an imported package.

Although such a control-flow path is impossible by
construction, we must avoid no-arg returns (even if
unreachable) in non-void functions.
Tested by adding a sanity-check that ssa.Return has the correct arity.
Also: added ssautil.Switches() test.

This fixes a case where adding an import when there are is no
existing import declaration can corrupt the position of
comments attached to types. This was the last known
goimports/astutil corruption case.
See golang.org/issue/6884 for more details.
Unfortunately this requires changing the API to add a
*token.FileSet, which we should've had before. I will update
goimports (the only user of this API?) immediately after
submitting this.
This CL also contains a hack (used only in this case of no
imports): rather than fix the comment positions by hand
(something that only Robert might know how to do), it instead
just prints the AST, manipulates the source, and re-parses
the AST. We can fix up later.

By using a simple (graph-based) serialization algorithm
and binary encoding, a significantly more compact export
data format is achieved than what the current compilers
use. Furthermore, the exporter and importer are completely
symmetric algorithms that are compact, and much easier to
change/expand.

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.
