Use better ctx for dict_attrunknown
Remove vp_free entry from ATTR_FLAGS.  it's no longer needed
Added simple wimax test
Unknown dictionary attributes are now talloc'd.

So use talloc_free()
In pairparse_any(), convert "known unknowns" to known

e.g.

	Attr-26.24757.84.9.5.4 = 0x1a99

will become

	WiMAX-PFDv2-Src-Port = 6809
Parse "known unknowns" to knowns, as with the previous commit
Unknown attributes are of type "octets", and therefore pointers
Parse "known unknowns" to knowns to map_from_cp(), too.

Abstract the code into a common function
Remove unused buffer
When printing templates, use ' instead of " for literals.

To match with the rest of the code and tests
Added map / template verify functions.
Check da's, too, in fr_verify_vp()
If the second parse is still unknown, don't use it
Function to add unknown attributes to the dictionary
Deal with map verify functions.  Missed in commit 21e7594e
verify da's by name, not by number in fr_verify_vp()

Because we have have multiple attributes of the same name,
but identical numbers
Create dictionary entries for unknown attributes

When loading the conditions && "update" sections.
Add a new map_from_fields_unknown(), which is a copy of
map_from_fields(), but which adds the dictionary entries.

This makes the server better deal with unknown attributes
