Turn off integer sanitization on android_memset. memset()ing is
expected to be a fast operation.
Avoid the use of the "while (size--) { }" construct, which harmlessly
underflows.

Call abort() on undefined or sketchy integer behavior.
Protects against integer overflow attacks.
Tested on Nexus 5 and Nexus 9 with no obvious problems.

Hash functions rely on overflow behavior, so whitelist them.
ATRACE_TAG_NOT_READY: use an unsigned constant when shifting bits.
Otherwise, the value overflows on shift. The users of this constant
assign it to a uint64_t variable.

(cherry picked from commit b602e6f9a3)
and run fsck with -f on clean shutdown instead.
With -f, fsck.f2fs always performs a full scan of the /data
partition regardless of whether the partition is clean or not.
The full scan takes more than 2 seconds on volantis-userdebug
and delays the OS boot.
With -a, the command does almost nothing when the partition
is clean and finishes within 20-30ms on volantis-userdebug.
When the partition has an error or its check point has
CP_FSCK_FLAG (aka "need_fsck"), the command does exactly the
same full scan as -f to fix it.

Using a getenv('OUT') in such a deep down function is a wrong design
choice. Replacing with explicit parameter that may be NULL in case
device specific files can be accessed from /.
Since TARGET_COPY_OUT_SYSTEM may be defined to something different than
system we also ensure that we use a path relative to TARGET_OUT to
compute path to fs_config_* files.

If a thread is created while the parent thread is "Background",
then the default timerslack value gets set to the current
timerslack value of the parent (40ms). The default value is
used when transitioning to "Foreground" -- so the effect is that
the timerslack value becomes 40ms regardless of foreground/background.
This does occur intermittently for systemui when creating its
render thread (pretty often on hammerhead and has been seen on
shamu). If this occurs, then some systemui animations like navbar
ripples can wait for up to 40ms to draw a frame when they intended
to wait 3ms -- jank.
This fix is to explicitly set the foreground timerslack to 50us.
A consequence of setting timerslack behind the process' back is
that any custom values for timerslack get lost whenever the thread
has transition between fg/bg.

If /dev/kmsg already exists, it's unnecessary for klog_init()
to create it's own copy. This avoids needing to grant the mknod
permission to everyone who uses kmsg. Typically the only time
/dev/kmsg doesn't exist is before ueventd starts.

User specified values of numInts and numFds can overflow
and cause malloc to allocate less than we expect, causing
heap corruption in subsequent operations on the allocation.

Fix broken mips64 build by replacing mips32r2-only android_memset.S.
Use HW-bonded pairs of 64-bit stores to fill 128 bits/cycle.
Rely on HW automatic cache prefetch optimizations.
Software cache prefetching is counterproductive on next mips cores.
New method is coded in C, and also works okay on non-Mips architectures.

strlcpy we provide for glibc/Windows rather than the Android one.
This also removes some unnecessary library dependencies.

Also make important events in init's life NOTICE rather than INFO,
and ensure that NOTICE events actually make it to the kernel log.
Also fix the logging so that if you have a printf format string
error, the compiler now catches it.
Also give messages from init, ueventd, and watchdogd distinct tags.
(Previously they'd all call themselves "init", and dmesg doesn't
include pids, so you couldn't untangle them.)
Also include the tag in SELinux messages.
