LogBuffer::log() returns either a negative number on error or a
positive number indicating the length of the message written.
Therefore, the check to notify kernel log readers of a new message
should be that this function's return value is > 0.

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.

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.)
