Add Fastboot support for flashing secondary images

Fastboot update and flashall will now flash secondary
images if provided, and if the --slot flag is not set
to 'all'. Also added flash-primary to preserve the
previous behavior, and flash-secondary to just flash
the secondary images.

Handle invalid suffix lists

Some devices will report an error string as a value
when unknown variables are queried. This can lead to
unexpected behavior, so we attempt to detect this case
by seeing if the suffix list doesn't make sense.

Call set_active after flashall and update

If the device has previously failed to boot, and the current slot is
marked as unbootable, we must call set_active to reenable the slot.

Support use local time for RTC

When default timezone isn't UTC, there will no persist.sys.timezone
under /data/property/, so init won't get the default timezone for
setting time from rtc.

This change adds a fallback to read the property when the persist file
does not exists.

Notice, the default property of persist.sys.timezone should be set in
/default.prop instead of /system/build.prop

NO_REF_TASK
Tested: set default timezone with Asia/Shanghai, make sure bios time
is correct in local time, reboot to android, the local time should
be correct.

add a property for controlling perf_event_paranoid

This adds a system property for controlling unprivileged access to
perf_event_paranoid. It depends on adding kernel support for
perf_event_paranoid=3 based on grsecurity's PERF_HARDEN feature to
completely disable unprivileged access to perf. A minimal port of this
feature is used in the vanilla Debian kernel by default.

It hides the non-hardened value as an implementation detail, since while
it is currently 1, it will probably become 2 in the future.

Rootdir: Add more asan.options support

Extend the asan.options file to read binary-specific configuration
from files out of /system. For early services, the system image
location is important as /data may not be available when they are
started.

Add a template that turns most sanitization off. At this point in
time, it is, however, impossible to get to a zero overhead state
after the fact. The template is meant to adapt a build after the
fact, and work around issues with LOCAL_SANITIZE := never.

Add a Make variable and rule copying the template to the path and
name expected by ASAN. Add SANITIZE_LITE to automatically add a
large set of options files.

adb: don't dup local socket fd.

SIGHUP handling depends on the local socket fd being fully closed in
order to trigger an event on its counterpart. Release the local socket
fd inside of Subprocess when returning it to ensure this.
