[PATCH 1/5] stk: Add agent registration and logic.

[PATCH 1/5] stk: Add agent registration and logic.

[Andrzej Zaborowski]

[-- Attachment #1: Type: text/plain, Size: 12175 bytes --]

This patch adds a skeleton that command implementations use in the
subsequent patches.

Icons and text attributes are not implemented in this series, I'll
send them separately.  There are slight differences from
doc/stk-api.txt, for example org.ofono.Error.EndSession can be used
to terminate either a user-initiated or UICC-initiated session.

Should we change the ".Error" part to something like ".Navigation",
since these are not error conditions and may be confusing?

Re: [PATCH 2/5] stk: Add menu related utilities.

Hi Andrew,

I suggest breaking up this giant constructor with many arguments into
two functions.  One that takes a setup_menu object and one that takes a
select_item object.  Then fills in the items appropriately.

Regards,
