Glibc >=2.32 exposes a gettid() which clashes with libcutils
thread.h, so add a check to not expose it if building against
newer glibc (ChromiumOS will still use glibc 2.27 besides 2.32).
Bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1182060
Test: Builds without errors on both glibc 2.32 and 2.27.

This function is no longer necessary, and uses a deprecated API
(mallopt(M_BIONIC_DISABLE_MEMORY_MITIGATIONS)). This function was
provided originally as part of libcutils because the original API was a
private android_mallopt.
The API is being reborn as a memory-init-specific mallopt. Given that
regular system components and apps will be able to call it directly,
it's not necessary to have a wrapper function in libcutils any more.

C++ thread_local is less code to write, and performs better. All known
users have been moved over already.

libcutils' thread local stuff is almost unused already, so let's try
harder to prevent new users. (In parallel I'll try to actually move the
four existing users off it, so we can actually remove this.)

Convenience API to disable memory mitigations, where we can specify
logging and also have a single place to update once a related bug is
fixed.

(cherry picked from commit 573fc58bad)
This makes the system property functions available on the host too, and
ensures a consistent view of system properties between libcutils and
libbase, if you have code running on the host that uses both.

The *kernel* header is "GPL-2.0 OR Apache-2.0", but the userspace
libcutils is just Apache-2.0 like all our code.

Helps with support of recovery and rollback boot reason history, by

This is to deprecate the sysprop change notification in atrace.
After this change, processes will only update their enabled tags
at the first atrace event. Previously we reloaded the tags as a
result of the sysprop changed Binder notification, which woke up
every process in the system.
Test: adb shell su root atrace -t 10 ss
Test: #define ATRACE_SHMEM 0; adb shell su root atrace -t 10 ss

Having libcutils ask ashmemd for ashmem fds results in unsatisfactory
performance/memory overhead. Introduce a duplicate of /dev/ashmem and
route to it instead.
Our goal remains as before, namely, use SELinux to phase out usage of
ashmem that doesn't go through libcutils.

This allows the library to be preloaded in the zygote.

Hex literals have the type of the first type they fit in. The reboot
constants are large enough that that's `unsigned` rather than `int`.

Move functions operating on cgroups from sched_policy.h in libcutils
into sched_policy_ctrl.h under libprocessgroup. This consolidates
cgroup-related functionality inside libprocessgroup.
