- Ensure that the compressed and uncompressed lengths in the data
descriptor match those in the central directory.
- Calculate CRCs for compressed entries and ensure that those CRCs
match the information in the central directory / data descriptor.
This is currently guarded by a flag and will be turned on at a
later stage.
- Finally, always trust the LFH when it comes to indicating the
existence of a data descriptor. We no longer require this info to
match the central directory to bring this in line with other zip
processing tools. (see NOTE in the included change).

adbd currently decides to use the QEMUD pipe if ro.kernel.qemu=1, as set
for ranchu. The Android container in Chrome OS doesn't have that
property set and it can't be set to 1 because it's used as equivalent to
"runs inside an emulator" throughout Android and changes the way
graphics are handled, whether Bluetooth is supported, etc., behaviour
that we do not want to trigger in Chrome OS.
adbd now also checks service.adb.transport to decide whether to use the
QEMUD (goldfish) pipe.
adbd still first checks for ro.kernel.qemu to preserve existing
behaviour and will still fallback to TCP if it can't use Goldfish.

The value of PRODUCT_{SYSTEM,VENDOR}_VERITY_PARTITION will be included
in the verity metadata of an image. For example:
PRODUCT_VENDOR_VERITY_PARTITION := /dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor
This makes the image cannot be shared for devices with different by-name
prefix:
/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor
/dev/block/platform/soc.0/7824900.sdhci/by-name/vendor
This change supports using a generic PRODUCT_{SYSTEM,VENDOR}_VERITY_PARTITION to
build image and replace it with the actual path at run time:
PRODUCT_VENDOR_VERITY_PARTITION := /dev/block/bootdevice/by-name/vendor ==>
/dev/block/platform/soc.0/7824900.sdhci/by-name/vendor

Current first stage mount only allows three mount points: system, vendor
and/or odm. This was introduced by project Treble to mount those
verified partitions early. However, there might be some other custom
partitions needs to be mounted early as well. This CL removes the
restriction and does first stage mount for whatever specified in
fstab-dt.

Fix a deadlock that happened when a reader/writer thread released a
transport while the hotplug thread attempted to handle a device
disconnection. Decrementing a transport refcount to zero would hold the
global transport mutex and attempt to take the usb handles mutex, while
the hotplug thread would hold the usb handles mutex and try to call
unregister_usb_transport, which would attempt to take the global
transport mutex.
Resolve this by making transport_unref not take the global transport
mutex.

Although prctl is declared as a varargs function, in actuality it takes
unsigned long arguments (after the first int argument). This patch
ensures that the slack value passed to prctl is correctly sized.
Without this change, the 32-bit ARM compiler places the 64-bit slack
value in registers r2 and r3, but prctl expects the first argument to be
in r1. For kernel versions < 4.6, set_sched_policy has not been
correctly setting the timer slack value in 32-bit ARM code.

If a device is unplugged while it's being processed, we can be inside

* changes:
debuggerd_client: increase pipe buffer size to max.
crash_dump: don't notify ActivityManager if it crashed.
crash_dump: clear the signal mask.
If a process tries to dump itself (e.g. system_server during ANRs),
crash_dump will block trying to write to its pipe if it's not
sufficiently large. Increase the pipe size to the max, and add a test
to make sure that it's always at least 1MB (the default value).

Because the zram_size type is unsigned int.so if ZRAM size great
than 2^31 -1, zram_fp will receive a negtive integer, while the
ZRAM driver only accept natural number.We need to use printf
formatting %u instand of %d.
Test: 1. Config the zramdisk size 2348810240 and build a ramdisk
2. Reflash device and check below command:
$adb shell dumpsys meminfo
$ adb shell cat /sys/block/zram0/disksize
ZRAM info display will be abnormal
3. Config the zramdisk size 2348810240 and apply with this
patch.
4. Retest to step 2 and the ZRAM info will be ok.
