bf3fff1a9e libutils: Fix bug in strstr16.
In the original code when target is an empty string
strlen16() would start reading the memory until a
"terminating null" (that is, zero) character is found.
This may happen because "*target++", at line 300,
would increment the pointer beyond the actual string.

bdddcab3bd Use target.linux for all linux kernel based targets
Now in Android.bp files, target.linux applies to all targets running a
linux kernel (android, linux_glibc, linux_bionic). So common
flags/sources/etc can be combined instead of copying them to each
target.

4852933707 Rename target.linux[_x86[_64]] to target.linux_glibc[_x86[_64]]
In the future, target.linux will apply to all targets running a linux kernel
(android, linux_glibc, linux_bionic). So move all current users to the specific
linux_glibc.

There will be another cleanup pass later that will move some instances back to
target.linux if the properties should be shared with target.android and
target.linux_bionic, but target.linux needs to be removed first.

5bae1b866d Make __android_log_assert behave more like libc asserts.
If we don't output to stderr too, not only is it annoying to shell users (who
won't see anything), it prevents us from writing better gtests that actually
make assertions about the assert message.

Hans Boehm
23c857ebd6 Make RefBase more robust and debuggable
This prevents two different kinds of client errors from causing
undetected memory corruption, and helps with the detection of others:

1. We no longer deallocate objects when the weak count goes to zero
and there have been no strong references.  This otherwise causes
us to return a garbage object from a constructor if the constructor
allocates and deallocates a weak pointer to this. And we do know
that clients allocate such weak pointers in constructors and their
lifetime is hard to trace.

2. We abort if a RefBase object is explicitly destroyed while
the weak count is nonzero.  Otherwise a subsequent decrement
would cause a write to potentially reallocated memory.

3. We check counter values returned by atomic decrements for
plausibility, and fail immediately if they are not plausible.

We unconditionally log any cases in which 1 changes behavior
from before. We abort in cases in which 2 changes behavior, since
those reflect clear bugs.
In case 1, a log message now indicates a possible leak. We have
not seen such a message in practice.

The third point introduces a small amount of overhead into the
reference count decrement path. But this should be negligible
compared to the actual decrement cost.

Add a test for promote/attemptIncStrong that tries to check for
both (1) above and concurrent operation of attemptIncStrong.

Add some additional warnings and explanations to the RefBase
documentation.
