The code previously assumed that write() took a non-zero number of clock
ticks. This is mostly true, but can't be guaranteed. Add a check to
avoid crashing if it's 0.

If a process requires executing fallback unwinder and the thread
crashing is not the main thread, the wrong unwinder is used.
Fix this case, and add a new unit test that causes an abort in
the non main thread.

Test: New unit test passes with fix and fails without.
Test: Ran debuggerd on swcodec process and it still dumps all threads.

We have a case where a service is requested to be started and does

if init is in a bad state.

The VMCompilationPerformance profile is used to run Isolated Compilation
in a Protected VM, normally during the device idle, where relevant
APEXes are staged.
The original VMCompilationPerformance introduced in aosp/2060891 does
not have any specific definition and requires vendors to customize it.
This change re-defines it as an aggregated profile with a default set of
existing profiles, so that performance can be reasonable by default.
This profile may be renamed to a more generic name later, e.g.
"SCHED_SP_COMPUTE".

Directories should always be encrypted unless there is a specific reason
they can't be. /data/bootanim is unencrypted without a specific reason,
so fix it to be encrypted. It is too late to use encryption=Require.
However, the contents of this directory doesn't need to be preserved on
updates, so we can use encryption=DeleteIfNecessary instead of
encryption=Attempt.

When system_server crashes or gets killed, it causes zygote to kill
itself, which in turn leads to killing all processes in the same
process group (all apps). This leaves empty process groups because
system_server is not there to remove them.
Purge empty process groups when init detects zygote death.

When system_server and zygote crash or get killed, all apps also get
killed but their process groups are left empty. Provide a function to
remove all empty process groups so that init can purge them when this
even happens.

Let's turn a bug into a feature... Since this code is built with intsan,
anyone who caused overflow here will have had an abort, so we know
no-one actually needs the BAD_INDEX return that was presumably the
original author's intent. So let's just mandate that, since it's a lot
harder to ignore an abort than it is to ignore an error return.
