NetLabel: Allow passing the LSM domain as a shared pointer
Smack doesn't have the need to create a private copy of the LSM "domain" when
setting NetLabel security attributes like SELinux, however, the current
NetLabel code requires a private copy of the LSM "domain". This patches fixes
that by letting the LSM determine how it wants to pass the domain value.
* NETLBL_SECATTR_DOMAIN_CPY
The current behavior, NetLabel assumes that the domain value is a copy and
frees it when done
* NETLBL_SECATTR_DOMAIN
New, Smack-friendly behavior, NetLabel assumes that the domain value is a
reference to a string managed by the LSM and does not free it when done
