Changes to init's behavior during early mount:
1. Mounting of tmpfs on /mnt is moved from init stage to early mount.
2. init creates /mnt/vendor used to mount vendor partitions.
3. If a device tree fstab entry for early mount specifies a mount point
under /mnt/vendor e.g. /mnt/vendor/foo, init will create
/mnt/vendor/foo mount point.
Bug: 64905218
Test: change dt fstab entry to mount persist to /mnt/vendor/persist;
mount point is created correctly, and partition is mounted in early
mount. See go/pag/1069774
Test: device boots with /mnt/vendor and previous contents of /mnt present,
and selinux label "mnt_vendor_file" is applied correctly.

Add ability to switch to the algorithm used by lowmemorykiller driver
for determining when to kill. It uses minfree levels to decide at which
levels of free memory and file cache to kill a process. oom_adj_score
is also determined by comparing current memory resources against minfree
levels.
ro.lmk.use_minfree_levels property is introduces for switching into this
mode. By default it is disabled.

(cherry picked from commit d273b6630d)
Current mechanism of getting system memory state by using sysinfo()
is not enough because it does not provide information about file cache
size which is needed to correctly assess memory state. Switch to using
data from /proc/meminfo that includes information provided by sysinfo()
and file cache size in addition to that.

This change allows bootstat to read the ro.boot.boottime_offset
property, which is set on devices where Android runs in a container.
This is because the CLOCK_BOOTTIME clock is not reset when (from
Android's perspective) the device restarts, since the host OS does not
restart itself.

Previously, processes started via `adb shell` have an oom_score_adj of
-1000, making them invisible to the oom killer. This makes running a
process that consumes all memory (e.g. by leaking in a loop) lead to
the entire rest of the system (including adbd, because of bad
heuristics in the kernel) being oom killed before getting to it.

OS X reports maxPacketSize as wMaxPacketSize * (bMaxBurst + 1) in the
deprecated GetPipeProperties function. Use the also-deprecated
GetPipePropetiesV2 API to get bMaxBurst and figure out what
wMaxPacketSize is. (This file is going to go away eventually, so don't
bother with switching to the recommended GetPipePropertiesV3, since
it would be a substantially larger charge.)

Events in the LogBuffer are supposed to be sorted by timestamp, but for a variety
of reasons that doesn't always happen. When a LogReader is reading from LogBuffer,
LogBuffer starts at the newest event, and scans backward through the list, looking
for the last event. Previously it would accept a couple that were a little bit out
of order, but if it found one that was ancient, it would just bail. This change
removes that check for the ancient messages. They are probably indicative of
something else upstream, but since there is no invariant of the list being sorted,
this change simplifies the search algorithm, and makes it look only at the previous
300 events.

Removes healthd from the build if -service.override

When -service.override is used, framework manifest needs

DEVICE_FRAMEWORK_MANIFEST_FILE.
