- Add a new offline unwinder test that fails without this change.
- Update unit tests.
- Refactor offline unwind tests to make it easier to add tests.

Specifically:
* rvalue references.
* St does not require N...E delimiters (explicit special case in the spec).
* ".cfi" suffixes.

A race condition occurs when one thread takes more than a second to get
scheduled to handle the signal we send to ask it to dump its stack.
When this happens, the main thread will continue on, close the fd, and
then ask the next thread to dump, but the slow thread will then wake up
and try to write to the new thread's fd, or trigger an assertion in
__linker_enable_fallback_allocator.
Do a few things to make this less bad:
- encode both target tid and fd in the shared atomic, so that we know
who each fd is for
- switch __linker_enable_fallback_allocator to return success instead
of aborting, and bail out if it's already in use
- write to the output fd right when we get to it, instead of doing it
whenever the dumping code decides to, to reduce the likelihood that
the timeout expires

Commit 3e235911 in bionic switched LP32's sigaction implementation over
to using the rt_sigaction syscall, matching LP64. Update our seccomp
policy to match.

The 16kB maximum for transfers was removed from
the kernel in 3.3. Devio has since supported
arbitrary transfer sizes through scatter gather.
See the following kernel patches for context:
"USB: change the memory limits in usbfs URB submission"
"usbdevfs: Use scatter-gather lists for large bulk transfers"

For strict VNDK runtime restriction, use ld.config.txt as a source
file. For treblized devices without BOARD_VNDK_VERSION, use
ld.config.vndk_lite.txt file.
Test: Build and boot on Pixel 2017 and 2018 devices.

Rename ld.config.txt.in to ld.config.vndk.txt and
ld.config.txt to ld.config.vndk_light.txt.
For FULL_TREBLE devices without BOARD_VNDK_VERSION, update the VNDK
library list in ld.config.vndk_light.txt with the actual VNDK list.

When persist.adb.trace_mask is used to enable verbose logging, avoid
exponential logging when a user runs `adb logcat`. As a side-effect,
set the minimum logging level to include everything when ADB_TRACE is
used on the client (which is something we want anyway).

Test: `adb shell 'setprop persist.adb.trace_mask; killall adbd'; adb logcat`

Switch asocket over to taking a std::string instead of apacket* for
data. This allows us to remove asocket specific fields from apacket*.

These checks were moved to after the read of the payload, which is too
late. Add a check before each read to avoid a heap buffer overflow.
