sharesec: Implement --view-all

Listing individual shares can be quite slow when you have a lot of shares. This
implements a --view-all option that prints something like

[share1]
REVISION:1
OWNER:(NULL SID)
GROUP:(NULL SID)
ACL:S-1-1-0:ALLOWED/0/FULL

[share2]
REVISION:1
OWNER:(NULL SID)
GROUP:(NULL SID)
ACL:S-1-1-0:ALLOWED/0/FULL
