Add initial handling of location paths (arrays of integers identifying
an entity in a .proto source file).
Expose path info in protogen; each descriptor has a Path field containing
its location path.
Format comments in protoc-gen-go. This contains one change from
github.com/golang/protobuf: Package comments are now included before the
package statement (but not attached to it) and use // comment syntax
instead of /* */. e.g.,
Before:
package test
/*
This package contains interesting messages.
*/
After:
// This package contains interesting messages.
package test

Copy/duplicate the logic in github.com/golang/protobuf for computing
package names and import paths and the names of generated files.
This is all sufficiently complicated that the code is the best
documentation. In practice, users should always set a go_package option
containing an import path in every file and pass the
paths=source_relative generator flag to get reasonable behavior.

The v2 API already assumes that type aliases are available elsewhere.
Thus, we can drop this dynamic check for type alias support.

The GoIdent type is now a tuple of import path and name. Generated files
have an associated import path. Writing a GoIdent to a generated file
qualifies the name if the identifier is from a different package.
All necessary imports are automatically added to generated Go files.

Copy generator.CamelCase for camel-casing names, with one change: Convert
'.' in names to '_'. This removes the need for the CamelCaseSlice function
which operates on a []string representing a name split along '.'s.
Add protogen.Message.
Reformat generated code.
Add regenerate.bash, largely copied from regenerate.sh.

Package protogen provides support for writing protoc plugins.
A "plugin" in this case is a program run by protoc to generate output.
The protoc-gen-go command is a protoc plugin to generate Go code.
cmd/protoc-gen-go/golden_test.go is mostly a straight copy from
the golden test in github.com/golang/protobuf.
