This allows Android to cleanly shutdown when running in a PID namespace
in a way that does not rely on adbd running. This is useful to allow
Android to be running in a container and its lifetime managed by an
OCI-compliant tool.

Test: `kill -TERM 1` as root is correctly dropped.
Test: `kill -TERM 1` from the init PID namespace causes init to cleanly shutdown.

New function to create the process memory object. This allows for
a future where different remote process memory objects could be created
depending on the way remote memory can be created. Even different local
memory objects that access memory without doing any checks.
It also allows MemoryRange objects to share one single process memory object
and could help if the process memory object caches data.
Small changes to MapInfo::CreateMemory to when some errors are detected.
- Always check if the map is a device map, instead of only if the name
is not empty.
- Check if a memory map is readable before creating the memory from process
memory.
Bug: 23762183
Test: Ran unit tests, unwound on device using the new code.

Unless a process logs that it is requesting a device to reboot, there
are no logs to show which process triggered a reboot. This change
introduces such a log in property service such that system initiated
reboots can be clearly blamed back to a calling process.

Test: reboot and check kernel log for reboot string

init: support loading odm sepolicy
Currently init merges two sepolicy cil files:
- /system/etc/selinux/plat_sepolicy.cil
- /vendor/etc/selinux/nonplat_sepolicy.cil
This change replaces nonplat_sepolicy.cil with the following two files:
- /vendor/etc/selinux/declaration/nonplat_declaration.cil
- /vendor/etc/selinux/vender_sepolicy.cil
And support merging another default (but optional):
- /odm/etc/selinux/odm_sepolicy.cil.
Bug: 64240127
Test: boot sailfish normally without odm.cil
Test: boot another device having odm.cil

As a VNDK-SP module, Android.bp must have 'vndk' tag as well as
'vendor_available: true'.
The 'vndk' tag for VNDK-SP module is formated as below:
vndk: {
enabled: true,
support_system_process: true,
},
VNDK-SP modules will be installed both in system/lib(64) as normal and
in system/lib(64)/vndk-sp as a vendor variant.

(cherry picked from commit 14d540a156)
- Add a method to get the max size of an elf file by reading the
section header offset + size. This will properly map an elf
file embedded into an apk, instead of just mapping in what is done
by the dynamic linker. It does assume that the section headers are
at the end of the elf file.
- Add new tests for the above functionality.
- Update the unwind_symbols tool to take an address for finding a
function instead of dumping the entire symbol table.
Bug: 23762183
Test: Unit tests pass, unwind through the camera process and verify
Test: the GoogleCamera.apk shows some function names.

We have seen that storing persistent properties in separate files
causes increased boot latency compared to if they were stored in a
single contiguous file.
This change creates a simple format for a contiguously stored property
file, and adds the support for arbitrary characters in the names of
persistent properties, which previously had been restricted. It has a
mechanism for converting older devices to the new format as well.

Test: boot bullhead with new properties
Test: boot bullhead and verify old properties are converted to the new
property file
Test: corrupt property file and ensure that it gets recovered from memory

Clang static analyzer worries that strcpy to a field may overwrites

- Change all load_base to load_bias in the test files.
- Add the test files to the backtrace_test.
- Add a function to get the path to the test libraries.
- Change aarch64 to arm64 for offline test code.
- Modify the offline tests so that they can be easily updated when
unwinding on any arch for any other arch is possible.
- Add tests of CreateNew for remote debugging.
Test: Ran unit tests on host and angler.

We've seen crashes due to processes exceeding the current soft limit
for open FDs of 1024, mainly due to increases in using FDs for shared
memory and gralloc memory objects.
There is not a compelling reason to keep this limit artificially low,
so we raise it to 32K. This matches my desktop linux limit, so it is
with precedent.
Bug: 64894637
Test: open 32K FDs in a process without failure then fail after 32K

Add a new service option, `rlimit` that allows a given rlimit to be
set for a specific service instead of globally.
Use the same parsing, now allowing text such as 'cpu' or 'rtprio'
instead of relying on the enum value for the `setrlimit` builtin
command as well.
Bug: 63882119
Bug: 64894637
Test: boot bullhead, run a test app that attempts to set its rtprio to
95, see that the priority set fails normally but passes when
`rlimit rtprio 99 99` is used as its service option.
See that this fails when `rlimit rtprio 50 50` is used as well.
Test: new unit tests
