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.

We introduce a method (*Interface).Complete(), which is intended
to be called from clients after all embedded interfaces have been
fully defined. For importers, this will definitely be the case
after the import has finished, so each importer have been updated
to do so, with the exception of the gcimporter, which does not use
embedded interfaces, therefore Complete() can be called immediately
after construction.
Building the method set separately from the constructor type caused
some problems with go/importer, which copies the types.Interface
object, leading to there existing two almost-identical interface
types referenced from interface method receivers, only one of which
has been completed. To avoid this situation, the importer has been
modified to construct the interface object only once.

Clients such as compilers need this information in order
to correctly link against imported packages.
This also adds support for the condensed import data format
where the priority information is stored as a suffix of the
condensed import data, as well as support for archive files.

GccgoInstallation.InitFromDriver currently parses
the output of gccgo -### to get the gcc version,
target triple, and library paths. At least with
Ubuntu's stock libgo5 package, the search path for
.gox files derived from the version is incorrect.
gccgo uses the DEFAULT_TARGET_VERSION macro when
constructing the search path; this value can be
retrieved from gccgo via the "-dumpversion" flag.

This can import all of the standard library, and has been tested
by using gotype to type check libgo with gccgo's export data (this
would be nice to automate, but I can't see a good way to do it,
not least because system-specific source files cause errors which
I needed to identify manually).
It includes a builtin export locator. Unfortunately I can't see a
more reliable way to locate the builtin export files than to parse
the output of 'gccgo -###'.
