protogen: include source comments in generated code

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
