r12203: Add the share path into the sharemode db. This involves
revving the minor version number for libsmbsharemodes (we
now have a new _ex interface that takes the share path
as well as the filename). Needed for #3303. Some code written
by SATOH Fumiyasu <fumiya@samba.gr.jp> included in the changes
to locking/locking.c. The smbstatus output is a bit of a mess
and needs overhauling...
Jeremy.
