[Dovecot] AIX: mntctl implementation for NFS quota support

[Ralf Becker]

Hi Timo, Hello list,

I've played around with dovecot-1.1.1 on AIX to get quotas (especially 
NFS quotas) to work. I've found that dovecot doesn't implement handling 
of 'mntctl' and so it is unable to determine filesystem mountpoints on 
AIX correctly.

Your'll find more information about 'mntctl' here:
http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.aix.basetechref/doc/basetrf1/mntctl.htm

Okay...

I've added mntctl support to 'lib/mountpoint.c' today. My tests are 
looking good and so I'd like to share the patch.
While I'm still not really familiar with dovecots memory management, I 
need someone who is familiar with it to have a look on my lines of code. 
Especially the usage or p_new, t_strconcat and p_free should be checked. 
:-)

To activate the patch you have to add "#define HAVE_VMOUNT_H 1" do 
'config.h'. Maybe someone wants to alter configure* to do this 
automatically?

And of course Timo, if you find it useful, you may include the code in 
one of the next dovecot releases.

Regards, Ralf
