Heschi Kreinick 63d31665e3 go/packages: add name= query
Add an implementation of name= for go list. It will be used to
implement goimports and godoc-like lookups by package name.

Imported a copy of the semver package from the stdlib to do version
comparison, and tweaked the gopathwalk API to include a hint about what
kind of source directory is being traversed.

Note that the tests, despite my best efforts, are not hermetic: go list
insists on doing version lookups in situations where it seems to me like
it shouldn't need to.

I think this implementation is ready for serious use. The one thing I'm
nervous about is that it currently does a substring match when looking
for a package name, so if you look up a package named "a" you will get
a huge number of results. This matches goimports' behavior but I don't
know if it's suitable for general use.
