The netd service and system server will use bpf syscalls to get network
stats information when kernel supported. And the syscall from system
server will need seccomp permission to run it.

Lock the FreeTrackData mutex during fork and reset it in the child.
Ensures that the FreeTrackData is consistent when forking from a
multi-threaded process, and that the mutex is in a defined state
in the child.

Setting PR_SET_NO_NEW_PRIVS actually breaks SELinux domain transition
(of debuggerd, for example). Do not set the bit when install the filter.
Instead, the caller must either have done it, or have CAP_SYS_ADMIN.

This is also slightly faster for the no VDSO case (56ns vs 66ns).

Introduce new flag to mark soinfo as TLS_NODELETE when
there are thread_local dtors associated with dso_handle
belonging to it.

ld-android.so exports exact same set of symbols
as linker. Since it is not supposed to be loaded
every symbol points to fail() method.

This will allow us to apply linker's version script to the "fake"
version of ld-android.so.

The libc.map.txt file already defines these three functions as having
been introduced in API 19, but these header files had declared them as
21 and up.
See https://android-review.googlesource.com/c/platform/development/+/233407
imaxabs is already declared as 19 and up.
Test: build-ndk-prebuilts.sh && ./update_platform.py &&
checkbuild.py && run_tests.py
Test: manually build app against 18 and 19

Also fix the tests for some missing benchmarks that have been
added recently.
Test: Ran bionic benchmarks tests and all pass.
Test: Ran bionic benchmarks to verify that there are no crashes.

C++17 removed a handful of things that are used in the libclang
headers, which are used by the versioner. Enable the flag that
re-exposes these until we have a C++17 compatible libclang.
Add a stub posix_memalign to the linker. libc++abi uses posix_memalign
when allocating exceptions, which the linker does not use.
Test: make checkbuild

Toolbox is moving to Android.bp, and its genrule needs access to these
kernel headers.

To pave the way to reducing app's kernel attack surface, this change
split the single filter into one for system and one for apps. Note that
there is current no change between them.
Zygote will apply these filters appropriately to system server and apps.
Keep set_seccomp_filter() for now until the caller has switched to the
new API, which I will do immediately after this before the two filters
diverse.
Also remove get_seccomp_filter() since it doesn't seem to be used
anyway.
Test: diff the generated code, no difference except the variable names
Test: cts -m CtsSecurityTestCases -t android.security.cts.SeccompTest

The examples on malloc options were erroneously
specifying to use 'guards' as an option to enable
both front and rear guards, whereas the correct
option name is 'guard.'

Make the cost of strto<signed> closer to the cost of strto<unsigned>
by removing an `if` from the inner loop. Previously a signed conversion
cost 10ns more than an unsigned one.
