stuff it's testing...

With the switch to libcrt.builtins, some symbols no longer becomes
exported. Add dummy references to them to force them to be exported.
This is to maintain backwards binary compatibility with ancient Android
versions.
x86 and x86_64 crashes with libcrt, keep using libgcc for now.

The new module type bionic_mountpoint wasn't mutated by the sanitizer.
As a result, it has been taking non-sanitized symbol libraries even for
sanitized builds. Fixing the issue by making the module type to
implement the cc.Sanitizeable interface so that it can be mutated by the
sanitizer.

When free_track option is enabled and malloc debug detects error in
VerifyFreedPointer flow, if freed pointer's usable_size is more than
g_debug->config().fill_on_free_bytes(), the error log is not correct.
The max. bytes printed to error message should be the max bytes to
cmp, not usable size.

The log priorities and ids are in an NDK header, available to everyone.
Move CHECK into its own header for now. This would be better if it was
more like the <android-base/logging.h> CHECK family, but I don't have an
easy way to do that without lots of copy & paste, so punting for now.

All of the heapprofd code assumes that it's the only hook that
has been enabled. Enforce that by disallowing heapprofd from
enabling if malloc debug or malloc hooks have been enabled.
Test: Ran all unit tests (bionic/malloc hooks/malloc debug/perfetto).
Test: Enabled malloc debug ran perfetto integration tests and verified
Test: that an error message goes to the log.

The change is a workaround of app compat issue until the app fixes the
issue.
Likely, the app does not only dlopen(), but open() the libicuuc.so
with the absolute path.
Note that platform uses the stub libandroidicu.so, not libicuuc directly.
This CL topic moves (not duplicates) libandroidicu from /system to
/apex. Even though /system/lib/libicuuc.so is kept in the default
namespace, but no one should be using it.
Some debug info after this CL:
$ adb shell cat /proc/<zygote pid>/maps | grep libicuuc
$ adb shell cat /proc/<app pid>/maps | grep libicuuc
Only /apex/com.android.runtime/lib64/libicuuc.so is found, not the
/system.

The pieces:
- The malloc common shared by static and dynamic code (malloc_common.cpp).
- The code for shared libraries that includes any dlopen'ing
(malloc_common_dynamic.cpp).
- The implementation of perfetto's heapprofd (malloc_heapprofd.cpp).
This makes it easier to see what's going on in the many different areas.
It should also make it easier to add the allocation capping option.
Other related changes:
- Update the unit tests for android_mallopt. All of the current options
don't work on static binaries, so make sure that is reflected in the test.
- A few names changes to make sure that all code is consistent.
Test: Ran tests (malloc hooks/malloc debug/perfetto/bionic unit tests).

Some of the greylist libraries can be in directories other than
/system/lib. For example, libnativehelper.so is moved from the directory
to /apex/com.android.runtime/lib.
Previous behavior for greylist libraries is to find the lib under
/system/lib while "within" the current namespace which is usually the
classloader-namespace. Since the libs no longer exist there, linker
fails to load it and no further attempt is made.
This change fixes the problem by loading the greylist libs "from" the
default namespace. Since there is a link from the default namespace to
the namespace where the moved libraries are intended to be loaded (e.g.,
the 'runtime' namespace for libnativehelper.so), the call is successful.

We need symbol files for /bionic/* paths.
New property "mountsource" is added to specify the "real" module that
the bionic mountpoint module is a mountpoint for. The real module
provides path to the unstripped elf file, which is installed to the
symbols/bionic/* path.

When the linker is invoked on itself, (`linker64 /system/bin/linker64`),
the linker prints an error, because self-invocation isn't allowed. The
current method for detecting self-invocation fails because the second
linker instance can crash in a constructor function before reaching
__linker_init.
Fix the problem by moving the error check into a constructor function,
which finishes initializing libc sufficiently to call async_safe_fatal.
The only important thing missing is __libc_sysinfo on 32-bit x86. The aux
vector isn't readily accessible, so use the fallback int 0x80.

Instead of every function being its own atomic, have a single
pointer that can be used to flip all pointers at once. This avoid cases
where the set of pointers can be in an partial switched state.
Also fix a few inconsistent naming of functions in the file.
Test: Ran unit tests (malloc debug, malloc hooks, perfetto).

The test was really only supposed to verify that mallinfo eventually
increase after allocations of certain sizes. Sometimes the mallinfo
returned decreases due to some compaction event, so don't fail in that
case.
