Summary:                    [patch] func_uri could use a QSFIELD function to
parse x-www-form-urlencoded data
Description: 
Hi,

I've added a QSFIELD function to func_uri.c to get fields from a
querystring. I thought this would be an acceptable way to read an ordered
dictionary gotten through e.g. func_curl.


[Synopsis]
Gets a single field from a application/x-www-form-urlencoded query
string.


[Description]
Returns the URI-decoded content from the <index>-th field with name
<field>
from query string found in variable <varname>.

[Syntax]
QSFIELD(varname,field[,index])


Example:

exten =>
_IDX!,n,Set(qsdata=field1=pe%20%25%40%26%3dna&field1=pe+na2&field2=pena3)
exten => _IDX!,n,NoOp(qsdata is ${qsdata})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field1,-1)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field2,-1)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field1,0)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field2,0)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field1,1)})
exten => _IDX!,n,NoOp(qstest ${QSFIELD(qsdata,field2,1)})

Set("qsdata=field1=pe%20%25%40%26%3dna&field1=pe+na2&field2=pena3")
NoOp("qsdata is field1=pe%20%25%40%26%3dna&field1=pe+na2&field2=pena3")
NoOp("qstest pe na2")
NoOp("qstest pena3")
NoOp("qstest pe %@&=na")
NoOp("qstest pena3")
NoOp("qstest pe na2")
NOTICE[4224]: func_uri.c:243 qsfield: Field field2= not found in query
string from qsdata on requested index
NoOp("qstest ")
