This series extends libsemanage and semodule with optional capability to
detect external changes to modules and perform a rebuild if there are
any. See patch 4 for motivation and more details.
The first three patches are preparatory cleanup/refactoring, patch 4
implements the libsemanage side of the feature described above, and
patch 5 adds a command-line option to semodule that allows to turn on
the feature.
Default behavior of libsemanage and semodule is not changed (apart from
added checksum calculation on each transaction, which however seems to
add no noticeable overhead based on benchmarks - see patch 4 for
details).
I'm posting this as an RFC mainly because I'm unsure about naming of the
new function(s) and the command-line parameter. Suggestions on better
names are welcome, as are any reviews/comments.
