Many functions are already marked "extern" in libsemanage's public
headers and this will help using the content of the headers in order to
automatically generate some glue code for Python bindings.

Allow an alternative selinux store root path to be used. The option
can be set in semanage.conf as store_root. If no option is provided, the
default path for the store_root is "/var/lib/selinux".

An HLL to CIL compiler must exist in the compiler_directory path which
is configubrable in semanage.conf. By default, this path is
/usr/libexec/selinux/hll/. The compiler name needs to match the HLL
language extension. For example, for pp files,
/usr/libexec/selinux/hll/pp must exist.
The HLL infrastructure uncompresses the HLL module and pipes the data to
the appropriate CIL compiler. The output CIL from the compiler is read
from another pipe, compressed, and saved to the module store as a cached
CIL file. This file will be used on all subsequent policy builds, unless
a new module is installed with the same name at the same priority, at
which point the cache is deleted and is subsequently rebuilt and cached.
A new option is added to semanage.conf, ignore_cache, which if set to
true will cause the cached CIL files to be ignored and all HLL files to
be recompiled and the resulting CIL to be recached.

* Exports the handle get/set default priority functions.

* Exports the module info management functions.
* Exports the get/set enabled status functions.
* Exports the module key management functions.
* Exports the module install, upgrade, remove info/key functions.

By default only the effective branch of a tunable conditional would be
expanded and written to raw policy, while all needless unused branches
would be discarded.
Add a new option '-P' or "--preserve_tunables" to the semodule program.
By default it is 0, if set to 1 then the above preserve_tunables flag
in the sepol_handle_t would be set to 1 accordingly.

This patch adds a function to turn off file contexts validation.
We need this for cross-installs in rpm, where we install policy
into a chroot that has binaries of a different architecture which
cannot be executed on the build system. So, we would like to use
this function to disable executing setfiles. This of course means
the file contexts could be invalid, but we're willing to take
that risk.

Currently any changes made to the policy which require committing a handle cause dontaudit rules to be re-enabled. This is confusing, and frustrating for users who want to edit policy with dontaudit rules turned off. This patch allows semanage to remember the last state of the dontaudit rules and apply them as default whenever a handle is connected. Additionally other functions may check for the file semanage creates to determine if dontaudit rules are turned on. This knowledge can be useful for tools like SETroubleshoot which may want to change their behavior depending on the state of the dontaudit rules. In the event that a the file cannot be created a call to commit will fail.

Add a semanage_mls_enabled() interface to libsemanage so that
semanage/seobject can be rewritten to use it to test whether MLS is
enabled for a given policy store rather than checking the runtime MLS
enabled status, which can be misleading when using semanage on a
SELinux-disabled host or when using semanage on a store other than the
active one. Sample usage:
from semanage import *
handle = semanage_handle_create()
rc = semanage_connect(handle)
rc = semanage_mls_enabled(handle)
