Change the shouldTraverse function to no longer keep a global map of
which inodes it's seen. Instead, whenever a symlink is seen for a path
name, check every directory entry in that path name and see if any are
the same inode as the current one, detecting any loop just from the
name itself.
More details of why the test was flaky are in the bug.

The go1.9 type checker now returns fake packages in addition to an
error if the package was not found at all. This changes the behavior
of guru in a release-specific way, requiring the test to be split into
a common part and a go1.9-specific part.
In hindsight, perhaps it would have been better to place the
expectation in a comment alongside the query so that they can be
easily enabled or disabled together. (The downside of that design is
that you can't batch-update all the expectations to match the actual
behavior.)

The existing API for querying values only allows directly querying
pointer-like values, or pointers to such values. The new, extended
queries make it possible to destructure values and access arbitrarily
nested pointers, such as fields in structs, or specific values in
tuples.
We use single Go expressions as the queries, which we further restrict
to a subset of the language (indexing, field access, pointer
dereferences and channel receives).
Instead of adding another map to Result, we return a *Pointer and
populate it during analysis. This does mean that a Config cannot be
reused for multiple analyses, as it now holds analysis-specific state.
That is, however, not a big problem as reusing one Config had little
use.
Since the new API can do everything the old could, it deprecates
AddQuery and AddIndirectQuery.

Prior to this change, handlerServer.GetPageInfo created a build.Context
starting with build.Default, and provided custom implementations for
its IsAbsPath, ReadDir, and OpenFile funcs. Those funcs would operate
on h.c.fs virtual filesystem.
https://godoc.org/go/build#Context.IsDir is documented as:
// IsDir reports whether the path names a directory.
// If IsDir is nil, Import calls os.Stat and uses the result's IsDir method.
IsDir func(path string) bool
IsDir was left as nil, and so the default implementation was used.
The default implementation uses os.Stat and isn't aware of the h.c.fs
virtual filesystem.
This appears to have been harmless in the past, but after the change to
go/build in https://golang.org/cl/33158, it started to interfere with
the operation of godoc. The command godoc began to fail to resolve
relative import path "." in directories that exist, because the
incorrect IsDir implementation was looking in real filesystem, rather
than the virtual one:
$ ./godoc fmt
2017/03/04 18:59:50 cannot find package "." in:
/target
$ ./godoc -http=localhost:6060
2017/03/04 19:00:07 cannot find package "." in:
/src/fmt
Providing a custom implementation of IsDir that is aware of the h.c.fs
virtual filesystem, and performs a stat operation on the correct path
there resolves that problem. It also fixes the failing tests.
Additionally, because the exact error string returned from
Context.Import has changed after https://golang.org/cl/33158,
and now contains the text "package not found" rather than the
underlying error text from filesystem caused by a failed ReadDir
operation, the expected error message from "./godoc nonexistingpkg"
in a test needed to be updated to "cannot find package". It's no longer
dependent on the operating system.
It might be desirable to provide more relevant detail in the error
message from cmd/godoc when a package is not found, but that should be
determined and done in a followup CL. The scope of this one is to fix
normal functionality.
This change follows update to go/build in https://golang.org/cl/33158.
