Before this fix, types such as
type T map[string]T
caused infinite recursion in the gob implementation.
Now they just work.
Fixes#1518.

Yesterday's change was too simple-minded and failed if an
interface value was being discarded. We need to parse the
data stream and remember any type information that arrives.
Also fix a minor bug when ignoring an interface: toss only what
we know about, not everything.

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.

The decoder was crashing when handling an rpc that expected
a struct but was delivered something else. This diagnoses the
problem. The other direction (expecting non-struct but getting
one) was already handled.

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.

2) compatibleType needs to use decoder's type map
