This is a rewrite of the existing implementation.
Three new variables are now needed to add/modify
the exisitng base policy. They are, BOARD_SEPOLICY_REPLACE
and BOARD_SEPOLICY_UNION which govern what files
are replaced and concatenated, and BOARD_SEPOLICY_DIRS
which lists the various directories that will contain
the BOARD_SEPOLICY_REPLACE and BOARD_SEPOLICY_UNION
policy files.

"sepolicy" is a phony target defined by the build system.
If you use it as dependency of a file target, you'll get unnecessary
rebuild.

A double free error occurs when building with non glibc
devices. The hdestroy() function frees all comparison
keys internally in these cases. So avoid an explicit
call to free().

Creates 2 new types:
- asec_apk_file : files found under /mnt/asec
when the asec images are mounted
- asec_image_file : the actual encrypted apks under
/data/app-asec

- allow all apps to connect to the keystore over unix socket
- dhcp runs scripts in /system/etc/dhcpcd/dhcpcd-hooks and creates/removes lease files
- mtp connects to dnsproxyd when a pptp vpn connection is established
- allow appdomain to also open qtaguid_proc and release_app to read qtaguid_device
- WifiWatchDog uses packet_socket when wifi comes up
- apps interact with isolated_apps when an app uses an isolated service and uses sockets for that interaction
- for apps with levelFromUid=true to interact with isolated_app, isolated_app must be an mlstrustedsubject

The app_* syntax was a legacy of the original approach of looking up
the username returned by getpwuid() and the original username encoding
scheme by bionic. With the recent changes to move away from this approach,
there is no reason to retain that syntax. Instead, just use _app to match
app UIDs and _isolated to match isolated service UIDs. The underscore
prefix is to signify that these are not real usernames and to avoid
conflicts with any system usernames.
Requires a corresponding change to libselinux.

Used when an app service is declared with android:isolatedProcess="true".
Place such processes in a separate domain, and further isolate them
from each other via categories.

The policy version suffix support was carried over from conventional
Linux distributions, where we needed to support simultaneous installation
of multiple kernels and policies. This isn't required for Android, so
get rid of it and thereby simplify the policy pathname.
We still default to generating a specific policy version (the highest
one supported by the emulator kernel), but this can be overridden
by setting POLICYVERS on the make command-line or in the environment.
Requires a corresponding change to libselinux.

When realloc creates the first block of memory, it must

to operate correctly.

When LINK_SEPOL_STATIC was not defined, symbol
log_warning was trying to be resolved by the linker.
That symbol was not defined as it should have been
log_warn and not log_warning.
When a key would be validated in key_map_validate(), an
unchecked key, like user, could cuase a segfault when
the se_key was getting free'd no matter what at the end
of the function, even if no se_key was alloc'd.
