[PATCH] SMPP Optional Parameters

Hello all,

as promised I rebased my SMPP TLV patch and post is here for review.
Please anybody if possible, write a userguide because I don't have time to
do it and without userguide this patch will not get into mainline.

Short description...

        In the config
group = smpp-tlv
name = some-name
tag = 0x1601
type = integer|nulterminated|octetstring
length = 4

In the msg struct I added meta_data field that can contain any
parameters not only for smpp. meta_data is formated as follows:
        meta_data = ?group?key=value&key1=value1?smpp?some-name=ABC
then SMPP module just set all TLVs that can be found in the smpp group of
meta_data.

With this approach it's possible to use this generic interface to put some
extra functionality into any SMSC module.

Example sendsms url:
lynx -source -dump 'http://localhost:13013/cgi-bin/sendsms?username=tester&password=foobar&to=123&from=456&text=text&meta-data=%3Fsmpp%3Fsome-name%3D123'

Example MO url:

http://localhost:123/bla/...&meta-data=%D&...

or with Post:
X-Kannel-Meta-Data

or with xml:
<meta-data>xxxxx</meta-data>


Please test it and let me know how it works.


P.S. I don't like how smpp_pdu_init and smpp_pdu_shutdown functions called.
They called from bb_smscconn.c but I have not found a better place to call
these. This may change in future ;)
