Subject: [PATCH 11/19] Add parallel cache for share_access entries, one per
 connection struct.

Needed as we cannot change the VFS ABI for 4.0.x, but need to add the
equivalent of 'uint32_t share_access' to the struct vuid_cache referenced
in connection_struct.

Exports 2 accessor functions - lifetime managed by talloc on the conn
struct list.

Subject: [PATCH 13/19] Add check_user_share_access()

This factors out the share security and read_only flag
setting code so this can be called from both make_connection_snum()
as well as check_user_ok(). Gives a consistent share security
check function.

Subject: [PATCH 18/19] Fixup the change_to_user_by_session() case as called
 from become_user_by_session()

Use inside source3/printing/nt_printing.c:get_correct_cversion().

Allow check_user_ok() to be called with vuid==UID_FIELD_INVALID.
All this should do is throw away one entry in the vuid cache.
