As per discussion in https://android-review.googlesource.com/#/c/221980,
we should be using #ifdef __APPLE__ rather than our own custom-defined
DARWIN for building on MacOS X.

Commit 3895fbbe0c ("selinux: Add support
for portcon dccp protocol") added support for the (portcon dccp ..)
statement. This fix will allow policy to be built on platforms
(see [1]) that do not have DCCP support by defining the IANA
assigned IP Protocol Number 33 to IPPROTO_DCCP.

This adds CIL and checkpolicy support for the (portcon dccp ...)
statement. The kernel already handles name_bind and name_connect
permissions for the dccp_socket class.

Add support to checkpolicy and checkmodule for generating CIL as their
output.
Add new options "-C" and "--cil" to specify CIL as the output format.

Since strtol(3) doesn't clear errno on success, anything that sets
errno prior to this call will make it look like the call failed. This
happens when built with ASAN.

In C, defining a function with () means "any number of parameters", not
"no parameter". Use (void) instead where applicable and add unused
parameters when needed.

Allow mls/constraint mls/validatetrans constraints to be displayed
in debug mode. If POLICY_KERN version is >=
POLICYDB_VERSION_CONSTRAINT_NAMES then the policy defined
types/attributes will be returned.

Fix a segmentation fault if the --handle-unknown option was set without
arguments.
Thanks to Alexandre Rebert and his team at Carnegie Mellon University
for detecting this crash.

This patch is proposed to solve Ticket #1 [1672486] (command line
binaries should support --version and --help).
It adds handling of -h, -V and the long formats --help and --version to
all binaries (checkpolicy/checkmodule).
It also adds handling of long options for some of the available options.
Manual pages have also been updated accordingly (and a few undocumented
options have been documented).
