The signal stack is sufficiently large for a single invocation of the
signal handler, but in cases where the signal handler needs to recurse,
(e.g. if our address space is limited by RLIMIT_AS), it's too small for
us to get to the part where we recognize that we've recursed and bail
out.

header-abi-checker will strip all functions from ABI dumps.

Currently, getnameinfo() will never issue a reverse DNS lookup if the first
byte of the IPv6 address is 0x00. This means it is not possible to do a
reverse DNS lookup for a NAT64 address if the NAT64 prefix is the well-known
prefix. Make this possible by treating the well-known prefix specially. This
is not needed for unicast NAT64 prefixes because they do not start with 0x00.

The changes needed to pick up time zone data files from
a mounted APEX directory. Code that looks for time zone
data now looks in a new location after checking for
data installed by the time zone updates via APK feature.
This hasn't been tested in combination with a real APEX but
it shouldn't do anything bad if the new path does not exist.

When a construct like:
if defined(something)
blocks1
elif 1
blocks2
else
blocks3
endif
The parser would put the first clause but then simply omit the elif and
put all of blocks2 without a terminating #endif. The code also did
something similar when the #else was an #endif.
Also convert all of the unit tests to real unit tests and only run
them if you run cpp.py by itself. Added new unit tests to cover the
new cases.
Test: Ran cpp.py unit tests.
Test: Reran update_all.py and verified nothing changed, and that running
Test: it on the new kernel headers that exposed this problem.

* changes:
libc: Match header annotations to version script
versioner: Build SymbolDatabase from version scripts
versioner: Add 28 to version list
libc: Add default __STRING implementation
With ELF TLS, the static linker assumes that an executable's TLS segment
is at a known offset from the thread pointer (i.e. __get_tls()). The
segment can be located prior to the TP (variant 2, x86[_64], sparc) or
after it (variant 1, arm{32,64}, ppc, mips, ia64, riscv).
We can't make our pthread_internal_t exactly follow the ordinary arm64
ABI (at least) because TP[5] is used for clang's -fstack-protector on
Android. Instead, reserve extra space after the TP (up to 16 words), which
will be followed by the executable's TLS segment.

(cherry picked from commit f397317e96)
Use <android-base/macros.h> instead where possible, and move the bionic
macros out of the way of the libbase ones. Yes, there are folks who manage
to end up with both included at once (thanks OpenGL!), and cleaning that
up doesn't seem nearly as practical as just making this change.

versioner will add another `#ifdef` guard and fail the test.

This commit defines a default `__STRING()` definition. There should be
a default definition because the unit test cases of versioner will
include `android/versioning.h` directly. We cannot include
`sys/cdefs.h` in `android/versioning.h` either because that will lead to
circular inclusion.

Some vendors may have been using the AIDs outside the oem ranges
for long that those aids need continue to be maitained for the
existing devices. We allow them countinue to use the old AID names
and values on device launch with P and before, to give them the
period of time to adopt the new AID scheme.

We don't have a host bionic version of
libclang_rt.asan-x86_64-android.so, so I'm using the android version,
which can't load liblog.so, since it's missing DT_RUNPATH that would
normally load liblog.so from a relative path to the .so.
