Downstream patches for this does it through NMSettings plugin, however
settings plugin are hard to maintain and complicated architecture wise
as well.
So directly create a connection profiles in-memory from the
nm-modem-ofono side. Those profiles are created in /run, and are not
added as a persistent connection, because connection state quite depends
on the state of ofono
This also allows us to drop the hack where we are keeping track of
active context/APN through the connection name, i.e if connection name
was in /imsi/context1 format, it was used. Instead now, Connection name
is actual context name which is user friendly ("Vodafone Connect" e.g.
in my case), and details like IMSI and context are stored internally.
[ratchanan@ubports.com:
- forward-ported to main branch.
- fold "wwan/ofono: handle context removal" into this commit.
- track the "preferred"-ness of the context and react accordingly.
Creates proxies for all retrived contexts to listen to changes.
While at it, also track name and type.
- use, instead of ignore, internet APN. Also support internet+mms APN.
- correct priv->contexts' value destroy function.
- factor out UUID generation as a helper function.
- handle the case where context dictionary is missing required keys.
- simplify nm_ofono_connection_new's arguments and rename to
add_or_update_connection. Makes it handle the case where the
connection already exists.
- also simplify other functions' arguments.
- clean up code and comments. Fix memory problems. Get rid of warnings.
