For clarity and performance reasons, we want the fast path of goimports
to be purely syntactic. Packages whose import paths don't match their
package names make this harder. Before this CL, we parsed each imported
package to get its real package name. Now, we make named imports for
such packages, and on subsequent runs we don't have to do the extra
work.
A package name matches its import path if the name is the last segment
of the path, or the next-to-last before a version suffix vNN. gopkg.in
style .vNN suffixes are considered mismatching.
The previous attempt (CL 145699) failed because I assumed we'd be able
to find all packages from scratch. That's not true if the import path is
completely unrelated to the package name. To avoid that problem, rather
than removing and re-adding mismatched imports, we just literally add
names to them.

Redesign fixImports to have a clearer workflow, and hopefully create
clear places to plug in go/packages. This change is mostly
performance/functionality neutral, but does clean up some corner cases.
The new flow centers around the pass type, which encapsulates the
process of loading information about the current code, adding possible
new imports, and trying to apply them. I'm hoping that it's easy to
understand what's happening just by reading fixImports, and that new
sources of information (e.g. a network service) fit well into that flow.
Where possible, I left the functions near where they were extracted in
hopes of making review easier, but it's probably not going to be easy.
Sorry. I might move them into a more reasonable order in a followup CL.
Notable modifications:
- The stdlib cache is restructured to match pass' internal storage.
- Sibling imports with conflicting names are considered.
- Package name lookups are batched, hopefully making it easier to plug
in go/packages.
Questions that might be worth answering:
- Should findImportGoPath really scan $GOROOT? Unless the user is working
on a development copy, it's totally redundant with the cache.
- What is the best way to combine candidates from multiple sources?
Right now the first one wins, and findStdlibCandidates relies on that
to get crypto/rand ahead of math/rand.
- In the third pass, should it assume sibling imports or should it
actually go load the exports? It didn't load them before, but that seems
arbitrary.

It used to rewrite golang.org/x/* imports to golang_org/x/*.
But https://golang.org/cl/147443 renamed golang_org/x to internal/x,
which broke the ability to run "go generate" in net/http, which runs
this command.
Given that net/http (and Go itself) is the only caller of cmd/bundle
or the -underscore flag, repurpose it to instead rewrite the
golang.org/x imports to internal/x, like CL 147443. But we keep its
name out of laziness and to minimize the number of cross-repo changes

We use the custom marker support to allow us to simplify the
annotations, making it much easier to understand the tests.

This exposes the ability to add markers to the public interface, and
changes the way markers are collected to make it so a standard call to
Expect can replicate the internal behaviour.
This allows custom rules to also add marks.
Also add a special EOF identifier that acts like a mark at the end of
the file in which it occurs.

Delivering each message in a go routine turned out to be problematic, there are some messages
that must be fully processed before later messages are started, and there was no way to guarantee that.
We now push concurrence handling up to the higher level, this has the disadvantage of not being able to guarantee
we respond to call messages correctly, but its a small price to pay.
The LSP currently processes each message fully in order blocking the handler, while we still work on basic
functionality.
