[patch 00/20] SMS D-Bus support and misc small patches

[Inaky Perez-Gonzalez]

From: Inaky Perez-Gonzalez <inaky.perez-gonzalez at intel.com>

This (3rd? 4th?) version of the patchset builds the D-Bus support on
top of the new _txq_submit() callback mechanism.

Note there are still a couple of opens that need discussion:

 - the message ID is generated based on the contents of the message --
   thus, the current way doesn't work. We need the caller to
   _txq_submit() to generate it. It's been left out of the STK
   stc.c:handle_command_send_sms() because I am not sure what is the
   right way to do it -- need feedback on that.

 - The generation of the SMS message ID based on contents still has
   shortcomings: if we submit two messages with the same content and
   destination number, the ID is the same [sms.c:sms_msg_send()]. What
   other factor would make sense to add? time?
