Restore some missing functionality to sig_analog.

Browse Source 
The main purpose of this commit is to restore missing functionality present in 
the ss_thread before all the sig related work was done. Two of the biggest
missing things were distinctive ring detection and cid handling for V23.
fxsoffhookstate and associated mwi variables have been moved inside sig_analog
as they were not being set properly as well.
