fix(apiserver): send exdata, exec cwd and exec home with submitted jobs (bug-1936)

Browse source 
Cause: modelJobToSubmit() filled only cmdline, execuser, launch_type and
pre/post-exec of job_startinfo_t, so the extended data the submit handler
builds (env, *_limit incl. -W run limit, file transfers, interactive mode),
the cwd and the exec home never reached the controller or the worker.

Fix: map the start info in a pure submitStartInfo() (exdata from
ExtendData, execcwd from ExecCWD or CWD, exechome from ExecHome) that
modelJobToSubmit copies into the C struct; decode exdata back in
cJobToModel/cJobArrayToModels so the store keeps ExtendData and CWD.
Reject extend_data the worker's parse_exdata() cannot take (not a JSON
object, over EXDATA_LENGTH-1 bytes) and drop an empty transfer list
instead of sending a null.
