Nathan Bossart 76fd342496 Provide a better error message for misplaced dispatch options.
Before this patch, misplacing a special must-be-first option for
dispatching to a subprogram (e.g., postgres -D . --single) would
fail with an error like

	FATAL:  --single requires a value

This patch adjusts this error to more accurately complain that the
special option wasn't listed first.  The aforementioned error
message now looks like

	FATAL:  --single must be first argument

The dispatch option parsing code has been refactored for use
wherever ParseLongOption() is called.  Beyond the obvious advantage
of avoiding code duplication, this should prevent similar problems
when new dispatch options are added.  Note that we assume that none
of the dispatch option names match another valid command-line
argument, such as the name of a configuration parameter.

Ideally, we'd remove this must-be-first requirement for these
options, but after some investigation, we decided that wasn't worth
the added complexity and behavior changes.
