Summary:                    [patch] Shared IMAP mailboxes can cause the server
to crash
Description: 
If the IMAP mailbox used to hold the voice messages is shared amongst a
number of users then the server can crash with problems inside the UW-IMAP
C-Client code. This is caused by multiple threads trying to use the shared
structure that the c-client code produces for the mailbox stream.

The particular installation is using Cyrus Imap server, with
authuser/authpassword set and multiple users having the same imapuser
setting.

    Add mutexes around accesses to the IMAP library interface.  This
prevents
    certain crashes, especially when shared mailboxes are used.
