Summary:                    Implicit declaration of copy yields broken
app_voicemail when building with IMAP support
Description: 
While upgrading from 1.4.37 to 1.4.39.1, I noticed the following anomaly
during compilation:

app_voicemail.c: In function 'vm_forwardoptions':
app_voicemail.c:5209: warning: implicit declaration of function 'copy'

I then observed that app_voicemail.so could not be loaded into the
resulting instance of asterisk:

[Jan 31 07:42:16] WARNING[30718]: loader.c:382 load_dynamic_module:
Error loading module 'app_voicemail.so':
/usr/lib64/asterisk/modules/app_voicemail.so: undefined symbol: copy

This apparent regression was introduced by r295200 in the 1.4 branch
(committed by jpeeler). In particular, lines
https://issues.asterisk.org/view.php?id=5209 and
https://issues.asterisk.org/view.php?id=5212 seem to be to
blame. They both call upon copy(), something which - as far as I can tell -
is defined alternately in imap/mail.h (from c-client) and in
app_voicemail.c itself if IMAP_STORAGE is _not_ defined, so I suppose
that's where the problem stems from. I don't know how to fix this in the
appropriate fashion so, for now, I opted to revert the changes that trigger
this problem.
