Summary:                    [patch] Race conditition in app_meetme leads to
crash
Description: 
I have been tracking down random crashes on a number of Asterisk servers
that rely heavily on app_meetme conference rooms. Depending on the server
load they can crash upto several times a week.

The majority of core dumps seem to be related to insufficient locking on
the conference 'userlist' linked list structure.

I have attached to patch to fix the locations where I think thread locks
are missing. Applies against 1.4.31. I have quickly glanced at the 1.6.x
branch and this looks to be required there too but I have no servers to
test that version on.
