The go/format.Node function fails silently on malformed ASTs, even
though it writes out an invalid tree containing the strings "BadExpr"
and "BadStmt". We fix this by checking for *ast.Bad{Expr,Decl,Stmt}
before running the function. Ultimately, this should be fixed upstream
and just return an error from format.Node.

Delivering each message in a go routine turned out to be problematic, there are some messages
that must be fully processed before later messages are started, and there was no way to guarantee that.
We now push concurrence handling up to the higher level, this has the disadvantage of not being able to guarantee
we respond to call messages correctly, but its a small price to pay.
The LSP currently processes each message fully in order blocking the handler, while we still work on basic
functionality.

I realized this was a mistake, we should try to keep the source
directory independent of the LSP protocol itself, and adapt in
the outer layer.
This will keep us honest about capabilities, let us add the
caching and conversion layers easily, and also allow for a future
where we expose the source directory as a supported API for other
tools.
The outer lsp package then becomes the adapter from the core
features to the specifics of the LSP protocol.
