Summary:                    [patch] realtime function does not return pair when
database value is null
Description: 
this is the same issue reported in
https://issues.asterisk.org/view.php?id=15615#c108403

the previous issue was closed, stating that it was corrected in 1.6.x. We
are still experiencing this issue in 1.6.0.13.

the function is rather useless if a the return does not contain the same
number of pairs on every query of the same table. 

this is a bigger issue in 1.6 than 1.4 since app_realtime is no longer in
1.6

still no go. only pairs where the column has a value are returned. What we
are expecting is that a column with a null value is in the string as such,
like "callerid=,username=3035551212,secret=123456,callgroup=" where
callerid and callgroup are in the table with null values. even with this
patch the values are ommited if null, and there are a a varying number of
pairs in the return, which changes the position of the needed data from
query to query.
