When adbd runs as root, it should transition into the
su domain. This is needed to run the adbd and shell
domains in enforcing on userdebug / eng devices without
breaking developer workflows.
Introduce a new device_banner command line option.

Don't assume that calling chown(filename, getuid(), getgid())
will always succeed. In the case of /sdcard, a file you create
will be owned by root, so the chown call will fail.
Instead, use uid=gid=-1 so that the chown call is truly a no-op.
Ignore the results of calling chmod. Again, for /sdcard, the
chmod call will never succeed, because the file isn't owned by
the shell user.

This cleans up most of the size-related problems in system/core.
There are still a few changes needed for a clean 64-bit build,
but they look like they might require changes to things like the
fastboot protocol.

Since ca8e66a8b0, init has
been handling reboots and filesystem unmounts. Remove obsolete

In case of bulk read/write failure or disconnect, transport_usb
calls usb_ffs_kick in order to force the daemon to re-open the
FunctionFS ep files as a way to soft restart the kernel driver.
However, there's no reason to always close the ep0 file, as it
would need to be reopened and the descriptors rewritten--this
is unnecessary, especially in the simple/frequent case of cable
disconnect, and causes the kernel driver to unbind and bind *all*
of the function drivers. This is causing USB Chapter 9 tests to fail.
Thus, try to reuse the same ep0 file handle across reconnects. In
case there is a failure, the ep1/ep2 opens would fail and all the
file handles get dropped. For the adb root case, the entire daemon
gets restarted anyway.

adbd changes the permissions of files uploaded by copying
owner's permission to group and other. This causes kernel
load failure if any changes are made to kernel modules
followed by ``adb push'' or ``adb sync'' because file mode
644 would become 666.
The change uses fs_config to get the target mode of files.
In addition, the SELinux file label is set incorrectly
on synced files. Set the label properly.

Bug: 12264775
handle_packet() in adb.c didn't check that when an A_WRTE packet is
received, the sender's local-id matches the socket's peer id.
This meant that a compromised adbd server could sent packets to
the host adb server, spoofing the identity of another connected
device if it could "guess" the right host socket id.
This patch gets rid of the issue by enforcing even more checks
to ensure that all packets comply with the description in
protocol.txt.
+ Fix a bug where closing a local socket associated with a
remote one would always send an A_CLSE(0, remote-id, "")
message, though protocol.txt says that should only happen
for failed opens.
The issue was that local_socket_close() called
remote_socket_close() after clearing the remote socket's
'peer' field.
The fix introduces a new asocket optional callback,
named 'shutdown' that is called before that, and is
used to send the A_CLSE() message with the right ID
in remote_socket_shutdown().
Also add some code in handle_packet() to detect
invalid close commands.
