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.

1) Be sure to use the eval-time encoder/decoder rather than
the compile-time decoder. In a few cases the receiver for
the compiling encoder was being pickled incorrectly into a
closure.
(This is the fix for issue 1238).
2) Get the innermost name right when given a pointer to an
unnamed type.
3) Use a count to delineate interface values, making it
possible to ignore values without having a concrete type
to encode into. This is a protocol change but only for the
new feature, so it shouldn't affect anyone. The old test
worked because, amazingly, it depended on bug #1.
Fixes#1238.

Remove err from the encoderState and decoderState types, so we're
not always copying to and from various copies of the error, and then
use panic/recover to eliminate lots of error checking.
another pass might take a crack at the same thing for the compilation phase.

The implemetation describes each value as a string identifying the
concrete type of the value, followed by the usual encoding of that
value. All types to be exchanged as contents of interface values
must be registered ahead of time with the new Register function.
Although this would not seem strictly necessary, the linker garbage
collects unused types so without some mechanism to guarantee
the type exists in the binary, there could be unpleasant surprises.
Moreover, the receiver needs a reflect.Type of the value to be
written in order to be able to save the data. A Register function
seems necessary.
The implementation may require defining types in the middle of
of sending a value. The old code never did this. Therefore there
has been some refactoring to make the encoder and decoder
work recursively.
This change changes the internal type IDs. Existing gob archives
will break with this change. Apologies for that. If this is a deal
breaker it should be possible to create a conversion tool.
Error handling is too complicated in this code. A subsequent
change should clean it up.

Because maps are mostly a hidden type, they must be
implemented using reflection values and will not be as
efficient as arrays and slices.

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
3rd set of files.

(the one-line struct types used in composite literals will become
one line again in another cleanup round; don't worry about them now)

preceded by a byte holding -n.
