In an effort to ensure that our development community does not
introduce new code without corresponding SELinux changes, Android
closely monitors the number of SELinux denials which occur during
boot. This monitoring occurs both in treehugger, as well as various
dashboards. If SELinux denials are dropped during early boot, this
could result in non-determinism for the various SELinux treehugger
tests.
Introduce /system/bin/auditctl. This tool, model after
https://linux.die.net/man/8/auditctl , allows for configuring the
throttling rate for the kernel auditing system.
Remove any throttling from early boot. This will hopefully reduce
treehugger flakiness by making denial generation more predictible
during early boot.
Reapply the throttling at boot complete, to avoid denial of service
attacks against the auditing subsystem.
Delete pre-existing unittests for logd / SELinux integration. It's
intended that all throttling decisions be made in the kernel, and
shouldn't be a concern of logd.
Bug: 118815957
Test: Perform an operation which generates lots of SELinux denials,
and count how many occur before and after the time period.

Somehow the code was still including this include from libbacktrace.
I think the libbacktrace include directory was coming from some
transitive includes. I verified that nothing in debuggerd is using
the libbacktace.so shared library.
Bug: 120606663
Test: Builds, unit tests pass.

charger needs to suspend the device when the power goes away
when it doesn't have root. These two files are marked with
group system, user system, mode 0600 in 'on boot', but
it is not executed in charger. Hence, move these actions
to 'on init'.
Test: no failure in libsuspend in charger

Add a new ashmem_init function that only dlopens libashmemd_client.
This allows the library to be preloaded in the zygote.
Test: boots, works

- Rename SparseBuilder to ImageBuilder, WriteSplitSparseFiles
to WriteSplitImageFiles, WriteToSparseFile to WriteToImageFile, etc.
- Add sparsify argument to ImageBuilder, WriteToImageFile, and
WriteSplitImageFiles
This allows lpmake to write non-sparse super image directly. Virtual
devices needs non-sparse images to work on.
Test: lpmake without --sparse
Test: liblp_test

- If file is unlinked, the mmapped region is still there.
- If file is truncated, a SIGBUS will be seen, and holding
the fd doesn't help.

This is required for read() to function correctly
in Windows since it behaves differently in text mode and
binary mode and may cause unpredictable behavior depending
on the contents of the image file.
