Re: Adding support for OMA-WAP Provisioning OTA

Basically most of the changes were made to ota_compiler.[ch].
  Here, if the compiler detects the OMA provisioning ID in the XML 
document (see ora_compiler.c:423 in the file), it passes a
flag to each of the callees that tells them to expect OMA-style 
settings. I had to change some of the internal parsing tables to 
accommodate OMA-style settings, while still handling Nokia/Ericsson 
style ok (this I've checked and it works ok).

In addition, the OMA spec says you can have a PIN to authenticate the 
settings to the ME, and a pin/security type (userpin, netwpin, 
usernetwpin or userpinmac) and describes how to use this to generate a 
SHA1/HMAC hash to be added to the binary message. These changes are in 
ota_prov.c -- some functions have had their protos changes as a result.

Finally, smsbox is modified to allow the sendota interface to take 
type=oma-settings&pin=1111&sec=userpin (or similar) to specify 
OMA-style settings.

There is a slight bug I discovered in the patch I sent: One needs to 
make  ota_compiler.c:421 read:
--
   if (document->intSubset &&
	document->intSubset->ExternalID &&
	strcmp(document->intSubset->ExternalID, "-//WAPFORUM//DTD PROV 
1.0//EN") == 0) {
--

That is add the additional check that document->intSubset->ExternalID 
is not NULL before accessing it :) -- I can do another diff if you 
like.

One more thing: For the HMAC computation, libssl is required. On my 
platform (OSX Panther) autoconf detection of this seems a bit flaky.

As I said, you need a new Series 40 or 60 Nokia (6800 and above, 6600 
and above), SonyEricsson P900 or some of the new Motorolla phones to 
test with. I have none of these! I had assumed all Series 60 support 
this, but nada.

  Let me know if you need more info.
