[evolution-patches] Patch for login synchronization b/w GW addressbook, calendar

[Harish Krishnaswamy <kharish novell com>]

hi,

 The attached patch adds synchronization between simultaneous login
requests issued by the addressbook, calendar (and the alarm daemon) for
the same account so that we authenticate to the server only once. 
This problem also reduces the occurrences of #64298 (problems due to
invalid sessions)  though not addressing it directly.

kindly review the same.
thanks,
harish
