Refactors allpaths to print an adjacency list from "from" to "to", instead of
just the nodes. This allows other tools like modgraphviz to print the subgraph.
For example, the following command:
cd $GOPATH/src/cloud.google.com/go && \
go mod graph | \
digraph allpaths cloud.google.com/go golang.org/x/text@v0.3.2 | \
modgraphviz | \
dot -Tpng -o graph.png
Generates the following graph.png: https://user-images.githubusercontent.com/3584893/60481727-df0a8680-9c4b-11e9-8df9-c581d599edd1.png
Also splits out the allpaths tests into their own test, and adds many test
cases.
This is a breaking change. The previous behavior returned vertices; now it
returns edges. If you relied on the previous behavior, use:
my-application | digraph allpaths <from> <to> | digraph nodes

If typeCheck() returned an error, we could get into a state where a
package had an entry in the pcache, but the package's files had an
empty "pkgs" map. When we got a DidChange event for one of the files,
no packages would get invalidated since the file's "pkgs" was
empty. This resulted in the cached typeCheck() error persisting
indefinitely. Fix by never caching pcache entries on error.
An easy way to reproduce the problem was to delete the package name
from a file. For example, edit "package foo" to be just
"package". This caused the package to get stuck with an "AST for %s
has an invalid position" error.

The first deadlock involved differing mutex acquisition order in two
code paths:
1. loadParseTypecheck() holds the "mcache" mutex then eventually
acquires the "handleMu" file mutex.
2. (*goFile).invalidateContent() acquires the "handleMu" mutex first and
then the "mcache" mutex.
Fix by changing the acquisition order in invalidateContent().
The second deadlock involved the file watcher. The two code paths
involved were:
1. (*goFile).GetPackages() holds the view mutex and eventually calls
(*WatchMap).Watch, which acquires the watcher mutex.
2. (*session).openOverlay acquires the watcher mutex as it triggers a
file's callbacks, and then the callback
"(*goFile).invalidateContent" acquires the view mutex.
Fix by not holding the watcher mutex as we invoke the callbacks.

Add some extra smarts when evaluating untyped constants as completion
candidates. Previously we called types.Default() on the expected type
and candidate type, but this loses the untypedness of an untyped
constant which prevents it from being assignable to any type or named
type other than the untyped constant's default type.
Note that the added logic does not take into account the untyped
constant's value, so you will still get some false positive
completions (e.g. suggesting an untyped negative integer constant when
only a uint would do). Unfortunately go/types doesn't provide a way of
answering the question "is this *types.Const assignable to this
types.Type" since types.AssignableTo only considers a constant's type,
not its value.
