New Revision: 372289

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=372289
Log:
Fix memory leaks in app_voicemail when using IMAP storage or realtime config

This patch fixes two memory leaks:

1. When find_user is called with NULL as its first parameter, the voicemail
   user returned is allocated on the heap.  The inboxcount2 function uses
   find_user in such a fashion when counting new messages, and fails to free
   the resulting voicemail user object.

2. When populate_defaults is called on a voicemail user, it wipes whatever
   flags have been set on the object by copying over the global flags object.
   If the VM_ALLOCED flag was ste on the voicemail user prior to doing so,
   that flag is removed.  This leaks the voicemail user when free_user is later
   called.

(closes issue ASTERISK-19155)
