(closes issue #7852)

Reported by: nic_bellamy
Patches:
      2006-10-03_svn_44249_voicemail_lockmode_v3.patch uploaded by nic_bellamy (license 213)

Add support for configurable file locking methods.  The default is "lockfile",
which is the old behavior.  There is an additional option, "flock", which is
intended for use in situations where the lockfile method will not work, such as
with SMB/CIFS mounts.
