The program secil2conf uses the libsepol function
cil_write_policy_conf() to create a policy.conf file from CIL policy.
By default a file called "policy.conf" will be created, but the "-o"
option can be used to write to a different file. The "-M" option can
be used to override the mls statement in CIL. The "-P" option will
cause tunables to be treated as booleans.

When running "make all" several times in the root directory of the
project, the following lines always appear (and the command takes some
seconds to complete on my system with a slow hard drive):
xmlto man secilc.8.xml
Note: Writing secilc.8
This is because "make man" always builds secilc.8 even though
secilc.8.xml has not been modified. Introduce an intermediate target to
avoid this behavior.

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.

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.

- Update Makefile to build the man page when just running 'make'

Converting to github markdown allows for easier integration with the
SELinux project wiki and viewing of documentation directly on github without
creating PDFs or reading through DocBook XML.
The conversion of DocBook to github markdown would not format tables or
keyword links properly. By maintaining the documentation in github
markdown in the repository, the content is well formatted with a table of
contents when viewing in the github wiki or in the repository.
The migration from DocBook to github markdown was done using Pandoc and
manual fixups. Mappings of CIL keywords to headings that were lost in the DocBook
conversion were added back. An introduction and design philosphy was
also pulled from the SELinux project wiki to provide more cohesion
to the current documentation.
Running make will now convert the github markdown into PDF and HTML.

Resolves https://github.com/SELinuxProject/cil/issues/3
An 'unordered' keyword provides the ability to append classes to the current
list of ordered classes. This allows users to not need knowledge of existing
classes when creating a class and fixes dependencies on classes when removing a
module. This enables userspace object managers with custom objects to be
modularized.
If a class is declared in both an unordered and ordered statement, then the
ordered statement will supercede the unordered declaration.
Example usage:
; Appends new_class to the existing list of classes
(class new_class ())
(classorder (unordered new_class))

This adds a userattribute statement that may be used in userroles and
constraints. The syntax is the same as typeattributset.
Also, disallow roleattributes where roles are accepted in contexts.
Specify a userattribute
(userattribute foo)
Add users to the set foo
(userattributeset foo (u1 u2))

So that building from top-level as per the README does not

The Android build does not like the symbol versioning introduced
by commit 8147bc7; the build fails with:
host SharedLib: libsepol (out/host/linux-x86/obj/lib/libsepol.so)
prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.15-4.8//x86_64-linux/bin/ld: error: symbol cil_build_policydb has undefined version
prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.15-4.8//x86_64-linux/bin/ld: error: symbol cil_build_policydb has undefined version LIBSEPOL_1.1
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Omit the versioned symbols and simply use the current interfaces
when building on Android.
Commit 36f62b7 also broke the Android build by moving secilc out of
libsepol, because the libsepol headers were not installed by the Android.mk
file.
Export the required libsepol headers for use by secilc and adjust secilc
to pick them up from the right location on Android.

Since the secilc compiler is independent of libsepol, move secilc out of
libsepol. Linke secilc dynamically rather than statically with libsepol.
- Move secilc source, test policies, docs, and secilc manpage to secilc
directory.
- Remove unneeded Makefile from libsepol/cil. To build secilc, run make
in the secilc directory.
- Add target to install the secilc binary to /usr/bin/.
- Create an Android makefile for secilc and move secilc out of libsepol
Android makefile.
- Add cil_set_mls to libsepol public API as it is needed by secilc.
- Remove policy.conf from testing since it is no longer used.
