When receiving an SMS, if the encoding is either GSM7 or UCS2, we will treat the
contents of the SMS as text; and if the encoding is either 8BIT or unknown, we
will just dump the contents of the SMS as data.
When creating an SMS, the user is not allowed to give both text and data, only
one can be given. We will use by default 8BIT when data is given, and guess the
best encoding if text is given.
Note that it's still possible to have SMS with neither text nor data, as in
delivery status reports.
This commit also handles the split of the input data in order to make it fit
into singlepart or multipart messages.
We will look for the part being notified in the CMTI indication directly in the
list of processed parts; and if we have it there already we won't re-process it.
Still, we may get several CMTI indications for the same part one after the
other, so it may still happen that the second CMTI comes *before* we have parsed
and created the part in the SMS list. For that case, the SMS list will reject
taking the part if there is already a part with the same storage+index already
processed.
This fix removes the `known_sms_parts' hash table, which was being handled
incorrectly.
This should fix https://bugzilla.gnome.org/show_bug.cgi?id=675175
If we get an error when telling the SMS list to take the new PDU, the caller is
the one responsible for freeing the part, so avoid doing it twice.

Instead of letting the plugins specify a default storage to use, just look at
the supported ones and use the best one.
"MT is preferred over "ME" or "SM", as "MT=ME+SM"
There is no point in specifying a default 'mem1' memory storage, which is used
for reading/listing/deleting, as those are operations that need a specific
'mem1' set each time.
Also, there is no point in specifying separate default 'mem2' and 'mem3' memory
storages, specially because now we allow Sms.Store() to specify a storage.
So, we will now only have a 'default' memory storage, which is applicable for
both 'mem2' and 'mem3' (storing, sending from storage and deleting).
