1902283053 Fix handling of non-waitable zombie threads. Now they are not
considered running, so WaitStop doesn't lock up and
breakpoints get installed and uninstalled.  We also don't try
to detach from them, since that will fail.

816e3da26d Make Value always represent an l-value and never a generic
container for values.

Instead of having one evaluator function that returns a
generic Value, there is now an evaluator function for each
generalized type that simply returns a native type.

The compiler is more type-safe now because there are almost no
type conversions at evaluation time and it's impossible to
invoke a nil evaluator function during evaluation.  This also
makes ideals and pointers really clean.

As an added bonus, expression evaluation should be faster
because it doesn't require heap allocation for every
intermediate value, type switches, or lots of conversions to
and from Value.  It also involves fewer function calls.

e76a335ada make the low-level encoder and decoder private and have them access byte.Buffers rather
than io.Readers and io.Writers.
change the Encoder/Decoder protocol so that each message is preceded by its length in bytes.

9211a7d413 Beginnings of a Go interpreter. This implements basic and
pointer types, supports literals, identifiers, type-checking
most unary and binary operators, "compiling" a few unary and
binary operators, and assignment and declaration statements.

aa1e8064b2 change HTTP access for RPC.
1. use CONNECT instead of GET.
   CONNECT has exactly the meaning
   we want; most of the time people
   connect to ip:port; we're connecting
   to /_goRPC_

2. wait for a successful HTTP response
   before assuming we are connected to
   the RPC protocol.  this allows better
   error reporting and also keeps the
   protocol alternating between speakers,
   so that the buffering in the HTTP request
   reader cannot accidentally eat some
   RPC bytes too.

gotest sometimes hangs, but not in HTTP.

gotest -match=Unknown hangs every few runs
even in a clean client.
