d169268a1a scanner cleanup - getting it ready to as a library
- removed unneeded code that accumulated over time
- change src from string to []byte (perhaps should be io.Read
but that has some other disadvantages)
- simplified interface

3689e221e8 Steps towards a general scanner/parser library for Go:
- converted more of AST and parser to use interfaces and explicit
structs for individual Go constructs (can be replaced now with
interface calls such that the parser becomes AST structure
independent, as suggested by rsc)
- added more tests (find all .go files under GOROOT)
- (temporarily) lost html links for identifiers when generating
html output
- TODO: lots of cleanups
