e40bbea95f libselinux: Add selabel_digest function
selabel_digest(3) if enabled by the SELABEL_OPT_DIGEST option during
selabel_open(3) will return an SHA1 digest of the spec files, plus
a list of the specfiles used to calculate the digest. There is a
test utility supplied that will demonstrate the functionality.

The use case for selabel_digest(3) is to implement an selinux_restorecon
function based on the Android version that writes a hash of the
file_contexts files to an extended attribute to enhance performance
(see external/libselinux/src/android.c selinux_android_restorecon()).
