Under certain conditions, poll() may raise the POLLERR
flag along with POLLIN, in which case the check for
(ufd.revents == POLLIN) results in an endless busy loop.
The following fix was applied to
hardware/libhardware_legacy/uevent/uevent.c
to fix a similar bug:

Obsolete RLE 565 logo is used nowhere,
because 565 framebuffer isn't used for years.
It's not necessary to keep this thing alive anymore.

Create a new "androidboot.selinux" option, to control how userspace
handles SELinux. This kernel command line can have three options:
* disabled
* permissive
* enforcing
"disabled" completely disables userspace support for SELinux. No
policy is ever loaded, nor is the SELinux filesystem /sys/fs/selinux
ever mounted.
"permissive" loads the SELinux policy, but puts SELinux into
permissive mode. SELinux policy violations are logged, but not rejected.
"enforcing", the default, loads the SELinux policy, and places
SELinux into enforcing mode. Policy violations are rejected.
This change addresses post review comments for change

When init starts up, immediately put SELinux into enforcing mode.
This is currently a no-op. We currently have everything in the
unconfined domain, so this should not break anything.
(if it does, I'll roll it back immediately)
If the kernel doesn't have SELinux support compiled in, then
don't try loading a policy and continue without SELinux protections.

Add an optional argument to the socket option for specifying
a SELinux security context for the socket. Normally the socket
security context is automatically computed from the service security
context or set using the seclabel option, but this facility allows
dealing with two scenarios that cannot be addressed using the existing
mechanisms:
1) Use of logwrapper to wrap a service.
In this case, init cannot determine the service security context
as it does not directly execute it and we do not want logwrapper
to run in the same domain as the service.
2) Situations where a service has multiple sockets and we want to
label them distinctly.

The Linux RNG may have little entropy during boot. As more and more
devices have a Hardware RNG, we mix in 512 bytes from Hardware RNG
(if present) into Linux RNG early during boot (after
wait_for_coldboot_done and before property_service_init actions in
init).
To avoid having to trust the output of Hardware RNG, we do not mix it
into the Linux RNG's primary pool or increase the Linux RNG's entropy
estimates.

The previous patch "init: verify size of property buffers passed
to property_get" incorrectly modified one of the callers,
resulting in ro.serialno, ro.bootmode, ro.baseband, and
ro.bootloader always being set to their default values.

With the old strdup() mechanism, it may return NULL if insufficient memory was
available. So we check the return value or do not use strdup to avoid null
pointer issue.

Adding a new location for policy files under
/data, the new location is /data/security. The
new location is used before attempting to use
any other location.
This requires a new directory to be created by
the init script and an update to the location of
the property_contexts file for property service.

To support runtime policy management, add support for reloading
policy from /data/system. This can be triggered by setting the
selinux.loadpolicy property to 1, whether from init.rc after
mounting /data or from the system_server (e.g. upon invocation of
a new device admin API for provisioning policy). ueventd and
installd are restarted upon policy reloads to pick up the new
policy configurations relevant to their operation.
