Label adb keys file and allow access to it.

The /adb_keys entry will only take effect if a restorecon is
applied by init.rc on a kernel that includes the rootfs labeling
support, but does no harm otherwise.

The /data/misc/adb labeling ensures correct labeling of the adb_keys
file created if the device has ro.adb.secure=1 set.

Allow adbd to read the file.

Add a domain for the recovery console.

Define a domain for use by the recovery init.rc file for
/sbin/recovery.  Start with a copy of the kernel domain
rules since that is what /sbin/recovery was previously running in,
and then add rules as appropriate.

Allow recovery to execute ashmem_device and tmpfs.

Requires execmem and ashmem_device:chr_file execute similar to bootanim
presumably for the display.

Did not see any cache_file execute denials and do not see any
exec of /cache files in the code, only reading/interpreting scripts,
so I removed cache_file rx_file_perms.

Did not see any tmpfs execute denials in /proc/last_kmsg but the
source code appears to extract the update-binary to a tmpfs mount
in /tmp and then exec it.  So I retained that rule.

Tested with adb sideload.

Make bluetooth, nfc, radio and shell adb-installable

bluetooth, nfc, radio and shell are not explicitly declared
in installd.te. This prevents applications in those group
from upgrading by "adb install -r".

You can reproduce the issue by following step:
 1. adb pull /system/priv-app/Shell.apk
 2. adb install -r Shell.apk
 3. install failed with the error log blow

[Error in logcat]
E/installd(  338): couldn't symlink directory '/data/data/com.android.shell/lib' -> '/data/app-lib/com.android.shell-1': Permission denied

Get rid of separate platform_app_data_file type.

The original concept was to allow separation between /data/data/<pkgdir>
files of "platform" apps (signed by one of the four build keys) and
untrusted apps.  But we had to allow read/write to support passing of
open files via Binder or local socket for compatibilty, and it seems
that direct open by pathname is in fact used in Android as well,
only passing the pathname via Binder or local socket.  So there is no
real benefit to keeping it as a separate type.

Retain a type alias for platform_app_data_file to app_data_file until
restorecon /data/data support is in place to provide compatibility.

Adding permissions needed to remove cache

During removing cache data using Zipper application, I found violation logs.

avc:  denied  { write } for  pid=198 comm="installd" name="cache" dev="mmcblk0p29" ino=81680 scontext=u:r:installd:s0 tcontext=u:object_r:download_file:s0 tclass=dir
avc:  denied  { remove_name } for  pid=198 comm="installd" name="downloadfile.apk" dev="mmcblk0p29" ino=82247 scontext=u:r:installd:s0 tcontext=u:object_r:download_file:s0 tclass=dir
avc:  denied  { unlink } for  pid=198 comm="installd" name="downloadfile.apk" dev="mmcblk0p29" ino=82247 scontext=u:r:installd:s0 tcontext=u:object_r:download_file:s0 tclass=file

Reproduction path is like below
1. Downloading Zipper application from Google Play (I used Zipper 1.9.9.2)
2. Clicking option and clicking "removing cache" button
3. Select "yes"
4. Violation show up

Get rid of separate download_file type.

This appears to have been created to allow untrusted_app to
access DownloadProvider cache files without needing to allow
open access to platform_app_data_file.  Now that platform_app_data_file
is gone, there is no benefit to having this type.

Retain a typealias for download_file to app_data_file until
restorecon /data/data support is in place to provide compatibility.
