A mispelling in the Makefile in the root directory prevented "make
distclean" to go into subdirectories.
In libsemanage/src/, semanageswig_python_exception.i was not cleaned by
"make distclean" because the target did not use $(GENERATED) and this
variable was being redefined in the Makefile.
Fix these two bugs.

We use the same lookup function for service contexts
that we use for property contexts. However, property
contexts are namespace based and only compare the
prefix. This may lead to service associations with
a wrong label.
This patch introduces a new back end for android
services with a stricter lookup function. Now the
service name must match the key of the service label
exactly.

The "-r" flag of sefcontext_compile now causes it to omit the
precompiled regular expressions from the output.

Adds the "-i" flag, which prints the version and
architecture identifier of the regular expression back end.

Serialized precompiled regular expressins are architecture
dependent when using PCRE2. This patch
- bumps the SELINUX_COMPILED_FCONTEXT version to 5 and
- adds a field to the output indicating the architecture
compatibility.
libselinux can cope with an architecture mismatch by
ignoring the precompiled data in the input file and recompiling
the regular expressions at runtime. It can also load older
versions of file_contexts.bin if they where built with
sefcontext_compile using the exact same version of the
pcre1/2 as selinux.

According to dbus upstream: "dbus-launch is fairly horrible code,
complicated by the historical need for it to support X11 autolaunching,
so the D-Bus maintainers would like to move it out of the critical path
and minimize its use."

On Android, certain discrepancies arise for unused functionality or
for dealing with the differences in Bionic libc. This patch includes
all the "ifdef'ing" required and introduces the BUILD_HOST define.
The BUILD_HOST define removes functionality not needed when building
libselinux for the Android build host machine.
Note that not all the libselinux src files are used to build
the host and target libraries on Android.

On Android for both the host build, and the target, certain
backends are not needed:
- X Backend
- DB Backend
- Media Backend
Introduce the following defines for removing them from the
built library:
- NO_X_BACKEND
- NO_DB_BACKEND
- NO_MEDIA_BACKEND
When configured with these options and an attempt
is made to use them, selabel_open() will return
ENOTSUP.

When a user installs a module, the filename is used as the module name.
This change was introduced with CIL language where a module name is not
stored in the module itself. It means that when a pp module has
different filename and stored module name, the filename is used instead
of the stored module name. It brings problems with compatibility for
scripts and modules which were built and used on older system and were
migrated to the new userspace.
This patch changes the behavior of semanage_direct_install_file() which
is used by 'semodule -i' so that when a module with pp language
extension is installed, it tries to get and use a stored module name
instead of a filename. A warning message is provided.
The warning message in policycoreutils/hll/pp is updated to reflect this
change:
$ semodule -X 400 -i /root/testfile.pp
Warning: SELinux userspace will refer to the module from /root/testfile.pp as testmod rather than testfile
$ /usr/libexec/selinux/hll/pp /root/testfile.pp testfile.cil
