Jan Schmidt 7bf3554228 structure: Change NULL and empty string handling 
Don't forbid the empty string "" in generic structures, only in taglists.
Properly allow the NULL string by adding special cases for serialising
and deserialising it. prop1=(string)NULL is the NULL string,
prop1=(string)"NULL" is the actual string with the value "NULL"
