7f7cb166c8 gob: several fixes.
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.

It's still not compiled in by default.

f593b37f23 gobs: error cleanup part 1.
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.

5d9064697b gob: allow exchange of interface values
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.

a3d1045fb7 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.

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.

Fix is to move all decoder state into the decoder object.
