Use an concurrency-limiting semaphore to reduce I/O parallelism in Import.
Also, start the producer in a new goroutine so that it runs in parallel
with the consumer. Paradoxically, this reduces the peak number of
goroutines.
Also, in buildutil.ForEachPackage, make the concurrency limiting
semaphore global, since I/O parallelism is a process-wide resource.

lexicalLookup reconstructs the lexical scope from the existing tree of

The optional Qualifier function determines what prefix to attach to
package-level names, enabling clients to qualify packages in different
ways, for example, using only the package name instead of its complete
path, or using the locally appropriate name for package given a set of
(possibly renaming) imports.
Prior to this change, clients wanting this behavior had to copy
hundreds of lines of complex printing logic.
Fun fact: (*types.Package).Path and (*types.Package).Name are valid
Qualifier functions.
We provide the RelativeTo helper function to create Qualifiers so that
the old behavior remains a one-liner.

Match gofmt's behaviour of closing the status buffer. Don't display the
buffer in case of success as we were going to hide it instantly again,
anyway. Also, instead of using delete-window, use
gofmt--kill-error-buffer. gofmt--kill-error-buffer uses quit-window if
there's a window for the buffer, kill-buffer otherwise.
quit-window only deletes the window if it was created explicitly for the
status buffer and if it is still displaying it. This way, we won't close
windows that the user created or repurposed himself.
Additionally, this change ensures that we don't leave a *go-rename*
buffer lying around when gorename succeeded.

Previously, gorename rejected all method renamings if it would
change the assignability relation.
Now, so long as the renaming was initiated at an abstract
method, the renaming proceeds, changing concrete methods (and
possibly other abstract methods) as needed. The user
intention is clear.
The intention of a renaming initiated at a concrete method is
less clear, so we still reject it if it would change the
assignability relation. The diagnostic advises the user to
rename the abstract method if that was the intention.
Additional safety checks are required: for each
satisfy.Constraint that couples a concrete type C and an
interface type I, we must treat it just like a set of implicit
selections C.f, one per abstract method f of I, and ensure the
selections' meanings are unchanged.
The satisfy package no longer canonicalizes types, since this
substitutes one interface for another (equivalent) one, which
is sound, but makes the type names random and the error
messages confusing.
Also, fixed a bug in 'satisfy' relating to map keys.
