lmkd uses PIDs to track processes, however occasionally a PID of a process
might be reused without lmkd detecting that. This can happen if originally
registered process crashes, PID numbers wrap around and the same PID gets
reused for a different process. In this situation lmkd might kill a wrong
process. To prevent this issue from occurring lmkd will track processes
using their pidfd. During process registration lmkd calls sys_pidfd_open
and stores returned pidfd with the process record. Returned pidfd will not
be reused until lmkd closes it which happens only after the process is
unregistered. This way lmkd ensures that process identification is unique
and can't be reused.

With pidfd polling support lmkd can detect process death without periodic
polling. Implement mechanism to detect kernel pidfd support using
pidfd_open syscall existence as an indicator. Implement the logic to use
pidfd to wait for process death.

There is an alarm() call that provides a 30 second timeout in case
logd is unavailable. The main reason for this is in the case that logd
is crashing, debuggerd is ptrace'ing logd, and tombstoned is
attempting to dump log messages. In this case, with no other checks
and without this alarm, tombstoned will deadlock when dumping log
messages.
However, tombstoned already has two mechanisms to prevent the above
situation from happening:
1) It checks that the thread name that is is dumping is either logd or
starts with "logd." and skips dumping logs in this case.
2) It does not dump logs if it is running in process for any process.
Calling alarm() or modifying signal handlers from general purpose
libraries is not recommended either, so without a strong reason to
keep this, this change removes it.
This also shortens the liblog.wrap_mode_blocks test time, since the 30
second issue that it ensures does not happen has been fundamentally
removed.
Test: `kill -8 `pidof logd`` succeeds without delay
Test: liblog, logd unit tests

The original code assumed that the load bias in the program headers
would be exactly the same as in eh_frame/eh_frame_hdr/debug_frame.
This isn't guaranteed, so add a section bias for use when creating
a DwarfSection. In addtion, make the load bias and section bias
a signed value. There is no reason that this value needs to be positive,
so don't force it to be.
Add a new offline test that has a different load bias in eh_frame than
in the executable load.
Add additional unit tests to verify the load bias values are set properly.
Clean up the tests in ElfInterfaceTest, making all tests names follow the
same convention.

This CL only draws boundaries between userspace and full reboots, and
adds some functionality that will be required for userspace reboot:
* Whenever device is shutting down is now controlled in reboot.cpp,
since during userspace reboot this state can change.
* Now it's also possible to restart handling of control messages inside
property service. In case of userspace reboot, init will restart it
after stopping post-data services.
* New userspace-reboot-requested trigger is added similar to shutdown
one for full reboot.
Test: adb reboot
Test: adb reboot userspace

As generic ld.config.txt will be covered with linker config generator,
ld.config.txt with previous vndk build is no longer required. This
change removes this part so there will be no unnecessary build step for
multiple vndk version build. Also vndk snapshot will have vndkcore and
vndkprivate files with version number, update_and_install_ld_config.mk
has been updated temporary for vndk_lite build.
