v2.4.3. packaging and documentation update.
Disable scan timeout by default (dangerous feature that can lead to threads deadlock).
Small code cleaning in lmgr_report.
Fixed typo in function name.
migration: better management of pending migration volume.

Pending migration volume was not accurate enough and resulted
in slow migration (file per file) when the size limit was closed
to be reached.
This patch distinguish in enqueued volume the amount of data that
was supposed to be copied, but was finally not (VOL_NOK).
Thus the pending volume can be computed as:
vol_sumitted - VOL_OK - VOL_NOK.
