Pass in parameters to the driver in stdin rather than through argv.
This allows us to more easily route parameters to the driver and add
more parameters without breaking users. The driver doesn't need to
have the same interface as go list, because it's unlikely the driver interface
will converge with the go list interface.
We still pass in the query "words" to the driver in the argv, because
that's as good a place as any, but there's no "list" command.
Question: should we add a "command" option to the driverRequest struct?

The documentation for Load says:
“Load returns an error if any of the patterns was invalid as defined
by the underlying build system. It may return an empty list of
packages without an error, for instance for an empty expansion of a
valid wildcard. Errors associated with a particular package are
recorded in the corresponding Package's Errors list, and do not cause
Load to return an error.”
Therefore, it should not be an error for a pattern to match no
packages. If the pattern is a literal package path that does not
exist, we should prefer to return a *Package for it with an error in
the Errors field.

This change adds the -buildflag argument to go/packages/gopackages,
which may be passed repeatedly to set config.BuildFlags. I felt -flag
was too vague.
config.Flags is renamed to config.BuildFlags for consistency, and
packages.findExternalDriver now passes -buildflag instead of -flag to
drivers. This will break existing drivers.

This deletes the raw and golist packatges, instead using the main
Package structure as the serialzied form between the build tool and the
loader.
This requires a few new fields on Package for information that we used
to hide, and some extra json tags on Package.
It also required Package to have custom JSON marshalling methods.

This allows an external binary (not go list) to be the source of package
information.
It uses a binary called gopackagesraw if present in the PATH.
The binary can be overriden by specifying the GOPACKAGESRAW
environment variable.
The command must accept the -test -deps -export and -flags, and take a
list of package patterns to match. It then returns a raw.Results followed by
the matching raw.Package structs in json format on stdout.
