For some reason, the memunreachable tests are rock solid on the
devices covered by APCT, but catch a ton of false-negatives on
hikey960, which show up as failures that look like:
system/core/libmemunreachable/tests/MemUnreachable_test.cpp:200: Failure
Expected equality of these values:
1U
Which is: 1
info.leaks.size()
Which is: 0
These happen when a stray copy of a pointer is lying around that
points to the memory it is expected to leak. The stray pointers
can be on the stack or in the jemalloc thread cache of freed
allocations, which is always considered active memory.
Add some extra cleanups to get rid of old pointers.
1. Clear the tcache when destructing UnreachableMemoryInfo
2. Clear the stack and tcache before and after each test
3. Make MemunreachbleTest.twice match MemunreachableTest.stack
Also fix MemunreachableTest.notdumpable, which was only passing
when run as root, which was bypassing what the test was trying
to cover. Make the test pass when run as non-root, and skip
when the test is running as root.

Add test and benchmark.
Also switch libbacktrace, libunwindstack, libmemunreachable
to use libprocinfo for map file reading.
The benchmark shows using libprocinfo speeds up map file reading
in libbacktrace and libunwindstack 18% - 36% on walleye.

This adds an API to fs_mgr for reading dm-linear tables out of device trees
and issuing device-mapper ioctls. The device tree code will be
implemented separately. The dm-linear structures in fs_mgr are organized
assuming we may want to pull them from sources other than DT (for
example, text files, binary blobs, or something hardcoded for testing).
File systems which are mounted from these logical partitions have
specific fstab requirements. The block device must be a partition name,
and if Verified Boot is used, that name must match the vbmeta partition name.
Second, the entry must have the "logical" fs_mgr flag. Example fstab
entry:
vendor /vendor ext4 ro wait,logical
Example fstab entry in device tree:
vendor {
compatible = "android,fstab";
dev = "vendor";
type = "ext4";
mnt_flags = "ro";
fs_mgr_flags = "wait,slotselect,avb,logical";
};

If BOARD_EXT4_SHARE_DUP_BLOCKS is true, "adb remount" will error saying

Since event sources can come and go asynchronously because of delayed
driver instantiation due to initialization or firmware upload, USB
attched devices, kernel module loads, or test automation sources like
monkey, add in inotify on /dev/input/ to support these possibilities.

The tags property is (and has always been) unused by Soong. The property has
been defined as a list of strings, and the `androidmk` converted any
LOCAL_MODULE_TAGS entries over to it, but we've never done anything with it.
In preparation for removing the definition from Soong, I'm removing it from all
Android.bp files in the tree.
Since this has never done anything, this is a no-op, but if you really did want
the Android.mk behavior, the proper way to define a module to be installed in
userdebug / eng builds is to use PRODUCT_PACKAGES_DEBUG or PRODUCT_PACKAGES_ENG
in the appropriate product makefile.

This commit excludes `qtaguid.cpp` from the VNDK-SP variant of
`libcutils.so` because the interface of `libnetd_client.so` may vary
between AOSP releases.
Besides, these functions don't work in vendor processes either because
VNDK-SP libraries are loaded in an isolated `vndk` linker namespace,
which cannot access `/system/lib[64]/libnetd_client.so` directly. This
change makes it easier to spot the issue at build time and saves several
bytes.
Test: Build aosp_walleye-userdebug and
/system/lib[64]/vndk-sp-$VER/libctuils.so no longer exports qtaguid_*
functions.

Add two states: connecting and authorizing, to disambiguate the offline
and unauthorized states, respectively.
Previously, devices would transition as follows:
offline -> unauthorized -> offline -> online
offline -> unauthorized (when actually unauthorized)
With this patch:
connecting -> authorizing -> online
connecting -> authorizing -> unauthorized (when actually unauthorized)
This allows test automation and the like to distinguish between offline
devices, unauthorized devices, and working devices without having to
do retry loops with arbitrary sleeps on their end.
