callagent: Introduce high level SIP Call
...
Introduce a high level class that can create multiple transactions,
handles the sequence numbers, the dialogs, the opened session and
provides a nice call, hangup, cancel, terminate interface.

callagent: Timeout fixes, pass the dialog along...
...
This is fixing a previous commit, fixes the timed out handling, attempts
to change the initial dialog -> confirmed dialog handling (but still
gets it wrong, it should compare the dialog, or just get a new dialog
from the response and check if it is compatible with the initial dialog).

transaction: Remember if an INVITE has been canceled.
...
Only the INVITE transaction can be canceled, when it gets
canceled we might or might not get a confirmation or we might
be too late to cancel things. With this flag we will be able
to do something sensible when we get a late final response.

transaction: Make the callbacks pass the dialog
...
The transaction now work on something called an initial dialog, e.g.
during a INVITE we go from an initial dialog to a confirmed dialog and
maybe create a session. Prepare the code to support this.
It is still not clear how callbacks, dialog confirmation and session
creation will be handled but it will somehow fit together.

provide a asFoldedString implementation, tell the folding code about
it, create a SIPToFromParam that holds the list of params.

grammar: Flatten the display_name to not do it later
...
For now we do not need to have fine grained access
to the string and it is easier to flatten things here
than later.

grammar: Parse the To/From header according to the grammar
...
Right now the UTF8 support for the displayname is still
missing and needs to be added later. The to_spec is not
part of the RFC but it makes our code more happy if things
look like the from_spec.

callagent: Dispatch received data with OsmoDispatcher
...
Dispatch the data from thre socket in a new context. This assures
that we will not run into locking issues. One day where we will have
VMs that can use multiple cores we might have a dispatcher set in
each transaction/session. The we could establish a rule that each
transaction is dispatched in the right/same queue.

callagent: Introduce timers, change locking, all work in progress
...
The idea is to introduce locking, but not within the callbacks,
allow to set a different SIPDialog, work on retransmit for simple
messages.
