This way, we don't fault in the entirety of our DSOs immediately;
instead, used pages are "sticky" in memory. Works only on kernel 4.4
and up: downlevel, we ignore the mlockall failure.
Once we get statically-linked lmkd in better shape, we'll just switch
to that.

Use the art dex file library to read the dex data.
Add unit tests for the UnwindDexFile code.
Bug: 72070049
Test: All unit tests continue to pass.
Test: Dumped the backtrace of the 137-cfi test while running in interpreter
Test: mode and verified that the stack trace is correct. Did this on host
Test: and for arm/arm64.

vendor_init doesn't have permissions to read rootfs labeled files, but
needs to read /vendor_file_contexts to do restorecon correctly. This
file is a file_contexts file, so labeling it as such seems appropriate.
Test: bullhead + vendor_init doesn't hit this audit

This commit links the vndk namespace of vendor processes to the default
namespace of vendor processes. allow_all_shared_libs is specified so
that VNDK extensions can link with other vendor libraries in
/vendor/lib[64].
Bug: 69824336
Test: Create a vndk-ext lib that links to vendor lib and use that
vndk-ext lib in a vendor executable.

Finishing a TODO from vendor_init, check SELinux permissions before
setting properties in vendor_init.

This commit moves /{odm,vendor}/lib[64]/vndk[-sp] to vndk namespace so
that vndk extension can override vndk libs from
/system/lib[64]/vndk[-sp].
Bug: 69824336
Test: Create libutils_ext locally and it can be called from
android.hardware.nfc@1.0-service.

The stack dump was not printing leading zeros for data after the
change to remove uintptr_t types from the libbacktrace API.
Bug: 65682279
Test: Created an arm tombstone and an arm64 tombstone and verified
Test: that the stack data has leading zeros.

These are halified. Instead launch blank_screen which
does the same task w/o init itself having binder
dependencies.
Bug: 70846424
Test: manual + reboot appears similar

I'd be not doing this for a while since some of this code doesn't
compile on host and libinit previously did. But after realizing
the property_service.cpp (libinit) references symbols in init.cpp
(init) and seeing a new linker error crop up due to that, it's time to
make the fix.
My only hold out previously was that libinit compiled on host bionic
and some of init (builtins.cpp, etc) do not, however given that we
don't actually have host bionic support or host bionic init tests,
that isn't a good reason. We can and should mock out the libraries
that aren't available with host bionic when ready.
Test: build, unit tests, boot

This CL implements a simple force_suspend(). This function takes a
timeoutMs argument that is currently ignored. It also uses a two-stage
init process that spawns the suspend_thread when autosuspend is in use.
Follow-up CLs will:
- Implement file locking to prevent multiple libsuspend instances from
starting multiple suspend threads in the system.
- Fully implement timout for force_suspend.
- Integrate force_suspend with suspend_thred.
Bug: 70669809
Test: autosuspend still works

Traceur app is being split out of shell user. Previously it logged to
shell's bugreports directory. It no longer has access, so it needs a
new, user-friendly file location to store trace data.
Bug:68126425
Test: Traceur can write and shell can read from this directory

In order to support the offline unwinding properly, get rid of the
usage of non-fixed type uintptr_t from all API calls.
In addition, completely remove the old local and remote unwinding code
that used libunwind.
The next step will be to move the offline unwinding to the new unwinder.
Bug: 65682279
Test: Ran unit tests for libbacktrace/debuggerd.
Test: Ran debuggerd -b on a few arm and arm64 processes.
Test: Ran crasher and crasher64 and verified tombstones look correct.
