use a better C++ exception wrapper to handle non OpenCV exceptions (as pure C++
one)

Git commit 4662dd94102f8144bc65ce1cb66d6b6cb1d500fd by Gilles Caulier.
Committed on 18/06/2014 at 14:22.
Pushed by cgilles into branch 'master'.

Libkface now depand of last stable OpenCV library version 2.4.9
This prevent internal crash int Cv:Algorithm that we cannot handle in libkface
as exception.
Now, Face Recognition do not crash but still report Exception at training
operations, especially about wrong Cv:Matrix size :

digikam(8673)/digikam (core)
Digikam::DImg::load:"/mnt/data2/photos/GILLES/NEW/Adrien/2010-04-13/20100413_009.jpg"
 :
JPEG file identified
OpenCV Error: Assertion failed (0 <= _dims && _dims <= CV_MAX_DIM) in setSize,
file /mnt/devel/opencv/modules/core/src/matrix.cpp, line 89
digikam(8673)/KFACE: cv::Exception training LBPH:
/mnt/devel/opencv/modules/core/src/matrix.cpp:89: error: (-215) 0 <=_dims &&
_dims <= CV_MAX_DIM in function setSize

It still a problem somwhere, but it's better than previous state.

Committed on 24/06/2014 at 12:32.
Pushed by cgilles into branch 'master'.

add more test before to commit/checkout compressed histogram data in Face
database, to prevent crashes, especially if data are corrupted from database.

With next digiKam 4.1.0, a lots of improvements/fixes have be done around face
management. Please give us a fresh feedback.

Note i recommend to delete face recognition database to prevent dysfunction due
to possible wrong data store in this container. Look where file is located in
my computer :

[gilles@localhost database]$ pwd
/home/gilles/.kde4/share/apps/libkface/database
[gilles@localhost database]$ ls -al
total 397028
drwx------ 2 gilles gilles      4096 juin  24 14:22 ./
drwx------ 3 gilles gilles      4096 juin  18 19:08 ../
-rw-r--r-- 1 gilles gilles 406543360 juin  24 14:22 recognition.db
[gilles@localhost database]$

After removing the face recognition database.
I'm still trying to crash it. No big memory leaks and no crash so far. (it
started with 1.7Gb of virtual memory and finished with 2.1Gb after looking at
~20.000 photos).
Great job.
