Using append simplifies the code and makes it work if
the initial capacity of the slice is smaller than the
number of items pushed.

The previous implementation was a mess with invariants
maintained inconsistently. Essentially reimplemented
the package:
- used a circular list as internal representation for
significantly simpler implementation with fewer
special cases while maintaining the illusion of
a nil-terminated doubly linked list externally
- more precise documentation
- cleaned up and simplified tests, added test case
for issue 4103.
No changes to the API or documented semantics.
All this said, I would be in favor of removing
this package eventually. container/ring provides
a faster implementation and a simpler and more
powerful API.
Fixes#4103.

go/doc: move Examples to go/ast
cmd/go: use go/doc to read examples
src/pkg: update examples to use new convention
This is to make whole file examples more readable. When presented as a
complete function, preceding an Example with its output is confusing.
The new convention is to put the expected output in the final comment
of the example, preceded by the string "output:" (case insensitive).
An idiomatic example looks like this:
// This example demonstrates Foo by doing bar and quux.
func ExampleFoo() {
// example body that does bar and quux
// Output:
// example output
}

godoc doesn't have the fu to present the example well, but this gives
us an example of an example to develop example fu.

Consequently, remove many package Makefiles,
and shorten the few that remain.
gomake becomes 'go tool make'.
Turn off test phases of run.bash that do not work,
flagged with $BROKEN. Future CLs will restore these,
but this seemed like a big enough CL already.

Having the test be in the container/heap package yields a cycle
container/heap (for the test)
-> testing
-> time
-> container/heap (for timerHeap)
Occasionally the linker would get mixed up, resulting in a test panic
in a very weird place.

I have written a tool to verify Printf calls, and although it's not
ready to be reviewed yet it's already uncovered a spate of problems
in the repository. I'm sending this CL to break the changes into
pieces; as the tool improves it will find more, I'm sure.

When it is known that there is already at least one element in the
list, it is awkwardly verbose to use three lines and an extra
variable declaration to remove the first or last item (a common
case), rather than use a simple expression.
a stack:
stk.PushFront(x)
x = stk.Front().Remove().(T)
vs.
stk.PushFront(x)
e := stk.Front()
e.Remove()
x = e.Value.(T)
[An alternative CL might be to add PopFront and PopBack methods].

Remove wasn't nil'ing the *Element.id. This property was exploited
by MoveToFront and MoveToBack internally, so I renamed the existing
Remove to "remove", and created an exported wrapper "Remove" that does
the right thing for the user's sake.
Also, saved an allocation by using *List as the id rather than *byte.

Package iterable has outlived its utility.
It is an interesting demonstration, but it encourages
people to use iteration over channels where simple
iteration over array indices or a linked list would be
cheaper, simpler, and have fewer races.

Also, move Do() to vector.go, so that Do() for IntVector and StringVector
is autogenerated.

autogenerated with "make generate".

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.
3) Manually changed src/exp/parser/parser_test.go
so that it doesn't try to parse the parser's
source files using the old syntax (they have
new syntax now).
4) gofmt -w src misc test/bench

the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.
this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.
Fixes#115.
