f39dc9fff2 More steps towards tracking of identifier scopes.
- provide scope to parse functions; if non-nil, parser uses the scope
  to declare and lookup identifiers
- resolve forward references where possible

758f2bc556 eliminate the package global name space assumption in object files
5g/6g/8g: add import statements to export metadata, mapping package path to package name.
	recognize "" as the path of the package in export metadata.
	use "" as the path of the package in object symbol names.

5c/6c/8c, 5a/6a/8a: rewrite leading . to "". so that ·Sin means Sin in this package.

5l/6l/8l: rewrite "" in symbol names as object files are read.

gotest: handle new symbol names.

gopack: handle new import lines in export metadata.

Collectively, these changes eliminate the assumption of a global
name space in the object file formats.  Higher level pieces such as
reflect and the computation of type hashes still depend on the
assumption; we're not done yet.

01b4f2dd23 Steps towards tracking scopes for identifiers.
- Identifiers refer now to the language entity (Object)
	  that they denote. At the moment this is at best an
	  approximation.

	- Initial data structures for language entities (Objects)
          and expression types (Type) independent of the actual
	  type notations.

	- Initial support for declaring and looking up identifiers.

	- Updated various dependent files and added support functions.

	- Extensively tested to avoid breakage. This is an AST change.

5a1d3323fe 1) Change default gofmt default settings for
parsing and printing to new syntax.

                  Use -oldparser to parse the old syntax,
                  use -oldprinter to print the old syntax.

               2) Change default gofmt formatting settings
                  to use tabs for indentation only and to use
                  spaces for alignment. This will make the code
                  alignment insensitive to an editor's tabwidth.

                  Use -spaces=false to use tabs for alignment.

3ca1b1d27f Continuation of issue 221 fix. When 8g or 6g or 5g are called with a
UTF-8 string, Yconv() converts it into an octal sequence. If the
string converted to more than 30 bytes, the str buffer would
overflow. For example, 4 Greek runes became 32 bytes, 3 Hiragana
runes became 36 bytes, and 2 Gothic runes became 32 bytes. In
8l, 6l and 5l the function is Sconv(). For some reason, only 5l uses
the constant STRINGSZ (defined as 200) for the buffer size.

80e17d6797 the AST walker currently provides no way to find out how the
nodes in the tree are nested with respect to one another.
a simple change to the Visitor interface makes it possible
to do this (for example to maintain a current node-depth, or a
knowledge of the name of the current function).

Visit(nil) is called at the end of a node's children;
this make possible the channel-based interface below,
amongst other possibilities.

It is still just as simple to get the original behaviour - just
return the same Visitor from Visit.

Here are a couple of possible Visitor types.

// closure-based
type FVisitor func(n interface{}) FVisitor
func (f FVisitor) Visit(n interface{}) Visitor {
	return f(n);
}

// channel-based
type CVisitor chan Visit;
type Visit struct {
	node interface{};
	reply chan CVisitor;
};
func (v CVisitor) Visit(n interface{}) Visitor
{
	if n == nil {
		close(v);
	} else {
		reply := make(chan CVisitor);
		v <- Visit{n, reply};
		r := <-reply;
		if r == nil {
			return nil;
		}
		return r;
	}
	return nil;
}

dc7355a974 Add flag -tabindent to gofmt: forces use of
tabs for indentation even if -spaces is set.

Changes to gofmt:
- added -tabindent flag
- don't recompute parser and printer mode repeatedly

Changes to go/printer:
- provide new printing mode TabIndent

Changes to tabwriter:
- implement new mode TabIndent to use tabs independent
  of the actual padding character for leading empty columns
- distinguish between minimal cell width and tab width
  (tabwidth is only used if the output contains tabs,
  minwidth and padding are always considered)
- fixed and added more comments
- some additional factoring

By default, -tabindent is disabled and the default gofmt
behavior is unchanged. By setting -spaces and -tabindent,
gofmt will use tabs for indentation but do any other
alignment with spaces. This permits a user to change the
visible indentation by simply changing the editor's tab
width and the code will remain properly aligned without
the need to rerun gofmt.

bae4f5085e cmd/cc: Fix -I switch to handle a path with blankspaces correctly
Currently, -I switch can't deal with a path containing spaces.
This commit simplify setinclude(), by removing the special case
of a string that had spaces. After this change, setinclude() will
merely add the given directories to the include path, if it does
not yet exist, and this approach works.

Will be needed for solving issue 115.

cgo/libmach remain unimplemented. However, compilers, runtime,

for all shipped functionality, this is done. Ship! ;)

d731dc8e72 Addressing issue brought up by dsymonds:
- When providing alternative spellings to a query, do not
  prefix it with a package qualifier as the suggestion may
  not have any results. Correctly filtering is quite a bit
  of work, and clicking the alternative spelling will always
  also show the qualified hits if they exist (but also others).
  Seems good enough for now.
- Give user feedback when the query syntax was wrong.
- Package names in search results are now links to the respective
  package documentation.
- Experimented with excluding main packages and test files
  from index with inconclusive results. Code is present and
  can be enabled by changing a flag in the source. This needs
  some more work.
