This fixes the following usability issues:
- when go-guru is called twice in a row and the output from the second invocation
is bigger then this output is not fully visible
- output window could be re-used by other packages (such as helm) that are not
usable with the shrank window

Major modes should use the C-c prefix followed by C-something. We'll
stick with C-o (oracle) since C-g is taken by go-jump-xxx (and in any
case C-g should be reserved for keyboard-quit.)

The parser does intra-file resolution. It's only a best-effort but
it's extremely fast, so we try it first and fall back to the loader-based
implementation if it fails.
Also:
- factor definitionResult so it doesn't depend on either go/types.Object
or go/ast.Object.
- guessImportPath: make importPath=="" result an error,
since you can't import the empty string. Simplify importQueryPackage.
- Make fastQueryPos continue in face of minor parse errors.
- describe: eliminate old TODO; suppress log statement.

go-guru--run has been split up to separate running the tool
from turning its output into compilation-mode form.
The definition command uses only the first part,
and parses its output in JSON form.
Added test, factoring the test script.

The -modified flag causes guru to read a simple archive file from stdin.
This archive specifies alternative contents for one or more file names.
The build.Context checks this table before delegating to the usual
behavior.
This will not work for files that import "C" since cgo accesses the
file system directly.
Added end-to-end test via Emacs.
Simplify findQueryPos (now: fileOffsetToPos)

Previously you had to describe a type to get this information,
which required two queries, and the need for this query is
extremely common.

As an optimization, the callers and callstack queries now avoid the
relatively costly pointer analysis in some common cases:
The callers of a function that is never address-taken can be enumerated
directly from the SSA representation.
Similarly, the callstack can be computed initially by ignoring dynamic
call edges; we run the pointer analysis only if no path is found in this
partial callgraph. As a bonus, this also causes the tool to
preferentially report all-static callpaths.
A callers query on fmt.Errorf now completes in 3 seconds instead of 8,
and a callstack query completes in 2 seconds instead of 8.
The new code is covered by the existing tests.
