When a process crashes, both ActivityManager and init will try to kill
its process group when they notice. The recent change to minimize the
amount of time a process is paused results in crash dumps being killed
before they finish as a result of this. Since anything that needs to be
low-latency is probably not going to be too happy if it crashes, just
wait for completion whenever we're processing a real crash.

Integer overflow sanitized builds are throwing an error on the while

It is possible for a match to only contain a context and not a schema,
or vice versa and in this case, the previously matched values should
continue to be used. The serializer already handles this case by
setting the index of the match to ~0u if there is not one, so this
change simply has the parser skip these values.

usb_device_get_string converts incoming ucs-2 text
to ascii by truncating the upper byte of each
character. This is error prone.
This patch introduces usb_device_get_string_ucs2
to access raw USB string descriptors, as well as
changes usb_device_get_string to replace any non
ascii character with '?'.

Test: Connected & disconnected a NuForceDAC.
Partners (entities other than AOSP) can expose their own system
libraries which are in /system/lib[64] to Android apps. This can be done
by adding the name of the libs into the files
/system/etc/public.libraries-<companyname>.txt.
There can be multiple of the txt files on a device, which is for the
case that multiple partners contributing to the same system image
have their own set of public libraries.
The public libraries MUST be named as lib<name>.<companyname>.so. This
is to prevent accidental exposure of AOSP-defined system private libs.
Note 1:
<companyname> doesn't need to be the same as the value of the sysprop
ro.product.manufacturer or anything that can be part of a file path.
Note 2:
This feature is not for exposing SoC-specific libs to Android apps. That
is already done by /vendor/etc/public.libraries.txt and is only for
libs in /vendor/lib[64].

This commit extracts /system/lib[64]/vndk and /system/lib[64]/vndk-sp
into another namespace in the vendor section. This commit is necessary
because LLNDK libraries (e.g. libc or libnativewindow) may otherwise
link to the shared libraries in /system/lib[64]/vndk-sp, which may be
older than the one LLNDK libraries built with.

1. Extend MAX_BACKTRACE_FRAMES to 256, as we can have callchains
with length near 256 when recording Android applications.
2. .eh_frame and .ARM.exidx doesn't know how to unwind from instructions
setting up or destroying stack frames. It can lead to wrong callchains,
which may contain pcs outside executable mapping areas. Stop unwinding
once this is detected.
3. Some CIE entries in .eh_frame/.debug_frame suggest unwinder reading
personality routine from memory. However, that is not available in
offline unwinding, and leads to ACCESS_MEM_FAILED error. Work around
this by returning all zero data when failed to read data for some
addresses.
4. Some libraries have empty .eh_frame_hdr but valid .eh_frame.
Work around this by building eh_frame_hdr manually.
5. Prefer to use .debug_frame than .eh_frame. Because the former
can unwind instructions setting up and destroying stack frames.

vndk_package is a phony module that includes ALL VNDK libs found in the
source code. As a result, VNDK libs that were actually not needed for
the device have been installed consuming storage. For example,
/system/lib/vndk/android.hardware.automotive*.so files were installed
even though walleye/taimen do not have automotive HALs.
VNDK libs are now installed by their link time dependencies (i.e. if a
vendor module uses libcutils, then /system/lib[64]/vndk-sp/libcutils.so
is automatically installed.).
By the way, there is a few number of VNDK libs that do not have any
link time dependency from vendor modules. They are always opened via
dlopen. In such cases, the vndk modules are added to `required`
or `LOCAL_REQUIRED_MODULES` of the module that dlopens them.
