5a9ad8b9e3 go/ast: use token.Pos instead of token.Position; adjust all dependent code
Specifically:

	* lib/godoc:
	- provide file set (FSet) argument to formatters where needed

	* src/cmd:
	- cgo, ebnflint, godoc, gofmt, goinstall: provide file set (fset) where needed
	- godoc: remove local binary search with sort.Search (change by rsc),
	  extract file set for formatters

	* src/pkg:
	- exp/eval: remove embedded token.Position fields from nodes and replace
	  with named token.Pos fields; add corresponding Pos() accessor methods
	- go/token: added file.Line(), changed signature of File.Position()

	* test/fixedbugs/:
	- bug206.go: change test to not rely on token.Pos details

	* added various extra comments
	* Runs all.bash
	* gofmt formats all of src, misc w/o changes
	* godoc runs

	* performance:
	- The new version of godoc consumes about the same space after indexing
	  has completed, but indexing is half the speed. Significant space savings
	  are expected from smaller ASTs, but since they are thrown away after a
	  file has been indexed, this is not visible anymore. The slower indexing
	  time is due to the much more expensive computation of line information.
	  However, with the new compressed position information, indexing can be
	  rewritten and simplified. Furthermore, computing the line info can be
	  done more efficiently.

        New godoc, immediately after indexing completed (best of three runs):

	  PID COMMAND      %CPU   TIME   #TH #PRTS #MREGS RPRVT  RSHRD  RSIZE  VSIZE
	44381 godoc        0.0%  0:38.00   4    19    149  145M   184K   148M   176M

	2010/12/03 17:58:35 index updated (39.231s, 18505 unique words, 386387 spots)
	2010/12/03 17:58:35 bytes=90858456 footprint=199182584
	2010/12/03 17:58:36 bytes=47858568 footprint=167295224

	Old godoc, immediately after indexing completed (best of three runs):

	  PID COMMAND      %CPU   TIME   #TH #PRTS #MREGS RPRVT  RSHRD  RSIZE  VSIZE
	23167 godoc        0.0%  0:22.02   4    17    132  129M   184K   132M   173M

	2010/12/03 14:51:32 index updated (24.892s, 18765 unique words, 393830 spots)
	2010/12/03 14:51:32 bytes=66404528 footprint=163907832
	2010/12/03 14:51:32 bytes=46282224 footprint=163907832

	The different numbers for unique words/spots stem from the fact the the
	two workspaces are not exactly identical. The new godoc maintains a large
	file set data structure during indexing which (probably) is the reason
	for the larger heap (90858456 vs 66404528) before garbage collection.

12da5a90e0 log: new interface
New logging interface simplifies and generalizes.

1) Loggers now have only one output.
2) log.Stdout, Stderr, Crash and friends are gone.
	Logging is now always to standard error by default.
3) log.Panic* replaces log.Crash*.
4) Exiting and panicking are not part of the logger's state; instead
	the functions Exit* and Panic* simply call Exit or panic after
	printing.
5) There is now one 'standard logger'.  Instead of calling Stderr,
	use Print etc.  There are now triples, by analogy with fmt:
		Print, Println, Printf
	What was log.Stderr is now best represented by log.Println,
	since there are now separate Print and Println functions
	(and methods).
6) New functions SetOutput, SetFlags, and SetPrefix allow global
	editing of the standard logger's properties.   This is new
	functionality. For instance, one can call
		log.SetFlags(log.Lshortfile|log.Ltime|log.Lmicroseconds)
	to get all logging output to show file name, line number, and
	time stamp.

In short, for most purposes
	log.Stderr -> log.Println or log.Print
	log.Stderrf -> log.Printf
	log.Crash -> log.Panicln or log.Panic
	log.Crashf -> log.Panicf
	log.Exit -> log.Exitln or log.Exit
	log.Exitf -> log.Exitf (no change)

This has a slight breakage: since loggers now write only to one
output, existing calls to log.New() need to delete the second argument.
Also, custom loggers with exit or panic properties will need to be
reworked.

All package code updated to new interface.

The test has been reworked somewhat.

The old interface will be removed after the new release.
For now, its elements are marked 'deprecated' in their comments.

Fixes #1184.

c606b964a0 go/typechecker: 2nd step towards augmenting AST with full type information.
- refine/define Scope, Object, and Type structures
  (note: scope.go has the addition of types, the rest is only re-organized
  for better readability)
- implemented top-level of type checker:
  resolve global type declarations (deal with double decls, cycles, etc.)
- temporary hooks for checking of const/var declarations, function/method bodies
- test harness for fine-grained testing (exact error locations)
  with initial set of tests

This is a subset of the code for easier review.

1f9dfa294f go AST: First step towards augmenting AST with full type information.
- change ast.Ident back to contain the name and adjust all dependent code
- identifier object information will be added again through an optional
  typechecker phase (in the works).
- remove tracking of scopes in parser - it's easier to do this in a separate
  phase (in the works)
- in godoc, generate popup info table directly instead of through a formatter
  for simpler data flow (at the expense of a little bit more code)

Runs all tests.

As a result of this change, the currently shown popup information
(const, var, type, func, followed by identifier name) will not be
shown anymore temporarily.

The command "godoc -src pkg_name" should output the interface of the named package, but it excludes all duplicate entries. Also the command "godoc -src pkg_name method_name" will output the source code only for one method even if there are more of them with the same name in the same package.
