command-line setting.
* cygwin.din: Export sexec* functions as function which returns ENOSYS
(i.e., sexec* is deprecated).
* dtable.cc (dtable::vfork_child_dup): Ensure that impersonation is restored
even on failure.
* exec.cc: Throughout, remove references to sexec* and _spawnve.
* pinfo.h: Remove _spawnve declaration.
* spawn.cc: Rename _spawnve to spawnve and use throughout.
(spawn_guts): Eliminate hToken argument and processing of same.  Just perform
special actions if impersonating.
(spawnve): Rename from _spawnve.
