Let's increase the receive buffer size for the NETLINK_KOBJECT_UEVENT
socket to 2MB. Unless a large number of uevents queue up, that memory is
not allocated anyways. The receive buffer size serves only as an upper
limit for the total amount of memory consumed by all skbs queued to a
specific socket.
We experienced situations where ueventd got blocked for multiple seconds
while writing to /dev/kmsg, and the receive buffer overflowed in the
meantime.

Treble system-as-root GSI needs to work on devices with and without /odm
partition. This change creates the following symlinks for devices without
/odm partition:
/odm/app ->/vendor/odm/app
/odm/bin ->/vendor/odm/bin
/odm/etc ->/vendor/odm/etc
/odm/firmware ->/vendor/odm/firmware
/odm/framework ->/vendor/odm/framework
/odm/lib -> /vendor/odm/lib
/odm/lib64 -> /vendor/odm/lib64
/odm/overlay -> /vendor/odm/overlay
/odm/priv-app -> /vendor/odm/priv-app
For devices with odm partition, /odm will be used as the mount point and
those symlinks will be hidden after mount.

With treble, the vendor kernel and ramdisk are supposed to be used.
But vendors always find new and interesting ways to break things:
$ cat /proc/device-tree/firmware/android/fstab/system/dev; echo
/by-name/system_a
$

The TrafficController inside netd also get notified when the interface
on device added or removed, and it need both ifaceName and ifaceIndex
information from Netlink event. Add the ifaceIndex in the event can
avoid the TrafficController to run if_nametoindex again when receive
the event.

* changes:
adb: remove meaningless const.
adb: convert Connection to a nonblocking interface.
adb: use soong version stamping.
adb: switch over to Android.bp.
Rename the existing Connection to BlockingConnection, add a nonblocking
Connection, and add an adapter between the two, to enable future work
to reduce the impedance mismatch from implementing a blocking interface
on top of nonblocking primitives.
While we're here, delete A_SYNC, and remove one layer of pipes when
sending a packet (replacing it with a condition variable when using
BlockingConnectionAdapter).

mapSysfsString return code is checked for negativity after being casted

(cherry pick from commit 979591b627)
Currently selection criteria for in-kernel vs userspace lmk is kernel
driver presence and device not being a Go device. This change removes
Go device check leaving kernel driver presence to be the only selection
criteria.

(cherry pick from commit caa2dc56fd)
New ro.lmk.kill_timeout_ms property defines timeout in ms after a
successful kill cycle for more kills to be considered. This is
necessary because memory pressure after a kill does not go down
instantly and system needs time to reflect new memory state. This
timeout prevents extra kills in the period immediately after a
kill cycle. By default it is set to 0 which disables this feature.

(cherry pick from commit 65f54a2665)
Record free memory at low vmpressure levels and whenever pressure
increases beyond low free up enough memory to downgrade memory pressure
to low. This is done by freeing enough memory to get to the max free
memory levels seen during low vmpressure.
The kill logic for Go devices is not changed as these devices are designed
to operate under high memory pressure.
