typeOf field is new tab-delimited field in dcd-client output, so you no
longer need to manually guess types / parse code. Calltips still yield
the actual written type, but in case of "auto", the typeOf column may
contain more useful info.
this is a or-combined mask of the request kinds which operate on
`request.sourceCode`. Before if a client sent a request without source
code (with empty source) to one of these commands, the server would
crash with an assertion failure, now the server returns an empty
response.
