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

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

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.

Revert "Remove obsolete workaround."
This reverts commit 1f3ac7583f.
Bug: 72143978
Bug: 24465209
Test: Tested failing case on sailfish, reverted back all CL's since
Test: 3471433 for b/24465209 and apps open
Changes:
- Change the register type from int16_t to uint32_t for the location data
and the Eval processing. This is because the special dex pc is > 65535.
- Add the ability for Dwarf register location information to point to a
register that is itself a Dwarf location register.
- Add dex_pc to the frame information.
- Modify the unwind tool to print the dex pc if non-zero.
This does not implement the printing of the dex information in anything
but the unwind tool. It's not the final form of this printing.
Bug: 72070049
Test: Ran new unit tests.
Test: Dumped stack while in interpreter running 137-cfi art test and
Test: verified dex pc is set to non-zero.

As we use different ld.config.txt per version, we don't need to

usbd checks whether adb is enabled by default, if yes,
would start adbd and would call into usb hal to configure
usb gadget stack.

Sometimes a process will have multiple shared libraries loaded
that have defined __jit_debug_descriptor. Specifically, art testing
will load libart.so and libartd.so, which would have broken unwinding
through jit'd code for art testing if libart.so winds up being found first.
In order to avoid duplicating the code for the linker to figure out
which one is live, change the algorithm to find the first non-zero
first_entry_ set in __jit_debug_descriptor.
Bug: 68396769
Test: Passes unit tests.
Test: Verified this can unwind 137-cfi on arm/arm64.

Properties right now can take any format, but that makes it hard to
specify an API for these properties as Treble intends to do.
Therefore this change introduces the idea of property types, described below.
1) 'string' this is the default type and allows any property to be set.
2) 'bool' this allows only boolean values (true|false|1|0)
3) 'int' and 'uint' these allow signed and unsigned integer values
respectively.
4) 'double' this allows floating point numbers with double precision.
5) 'size' this allows for strings matching [0-9]+[gkm].
6) 'enum' this allows only a specific set of space deliminated values
to be set, e.g. 'enum allow these strings' only allows one of 'allow',
'these', or 'strings' to be set.
Bug: 70858511
Test: unit tests, test that properties are only set if their type matches
