multipath: Validate multipath actions more thoroughly in multipath_parse().
		
The stricter validation requires updates to the calls to test-multipath
to supply a valid n_links value.  test-multipath doesn't actually use
that value (it runs over different values in an internal "for" loop), so
this doesn't change any behavior.

Also adds a test to exercise each possible multipath_parse() error message.

ofp-parse: Don't segfault when an OpenFlow action's argument is missing.
		
Some actions checked that 'arg' was nonnull before attempting to parse it
but a lot of them didn't.  This commit avoids the segfault by substituting
an empty string when no argument is given.  It also updates a few of the
action implementations to correspond.

nicira-ext: Fix comment.
		
Multipath actions only support registers as destinations, but this was
defined by reference in nicira-ext.h and the referenced text changed.
