Bug: 25567964
Since linker-namespaces are enabled for all target_sdk_versions
and there is no longer need in workarounds in libnativeloader -
remove unused target_sdk_version parameter for internal calls.
This also brings libnativeloader closer to aosp/master

adbd on device kicks the usb connection when usb IO fails. But to notify
adb on host to reconnect it, adbd needs to close ep0 to reset the usb
connection. Otherwise, adb on host cann't connect the device unless the
usb cable is reconnected or adb host server is restarted.
This can be tested by using `adb reconnect device` command.

Add comment that SharedBuffer is deprecated.
Both aref and SharedBuffer had memory ordering bugs. Aref has no
clients.
SharedBuffer had several bugs, which are fixed here:
mRefs was declared neither volatile, not atomic, allowing the
compiler to, for example, reuse a stale previously loaded value.
It used the default android_atomic release memory ordering, which
is insufficient for reference count decrements.
It used an ordinary memory read in onlyOwner() to check whether
an object is safe to deallocate, without any attempt to ensure
memory ordering.
Comments claimed that SharedBuffer was exactly 16 bytes, but
this was neither checked, nor correct on 64-bit platforms.
This turns mRef into a std::atomic and removes the android_atomic
dependency.

Convert to use std::atomic directly.
Consistently use relaxed ordering for increments, release ordering
for decrements, and an added acquire fence when the count goes to
zero.
Fix what looks like another race in attemptIncStrong:
It seems entirely possible that the final adjustment for
INITIAL_STRONG_VALUE would see e.g. INITIAL_STRONG_VALUE + 1,
since we could be running in the middle of another initial
increment.
Attempt to somewhat document what this actually does, and
what's expected from the client. Hide the documentation in
the .cpp file for now.
Remove a confusing redundant test in decWeak. OBJECT_LIFETIME_STRONG
and OBJECT_LIFETIME_WEAK are the only options, in spite of some
of the original comments.
It's conceivable that either of these issues has resulted in
actual crashes, though I would guess the probability is small.
It's hard enough to reason about this code without the bugs.
