After switching libm from libgcc to libcrt.builtins, some of the symbols
are no longer getting included in libm, causing the compiler to complain
about missing symbols from the version script. Explicitly export them in
libc (since libm depends on libc).

Introduce a new flag ANDROID_DLEXT_RESERVED_ADDRESS_RECURSIVE which
instructs the linker to use the reserved address space to load all of
the newly-loaded libraries required by a dlopen() call instead of only
the main library. They will be loaded consecutively into that region if
they fit. The RELRO sections of all the loaded libraries will also be
considered for reading/writing shared RELRO data.
This will allow the WebView implementation to potentially consist of
more than one .so file while still benefiting from the RELRO sharing
optimisation, which would otherwise only apply to the "root" .so file.

Gold isn't emitting these symbols, so we don't necessarily have the
support for them (gold is still the default for most architectures in
the NDK).

We still don't have a good way to create vendor AIDs in the system or
other non-vendor partitions, therefore we keep this check disabled.

Life is easier if we just keep test code in the same directory as the

With the switch to libcrt.builtins, some symbols no longer becomes
exported. Add dummy references to them to force them to be exported.
This is to maintain backwards binary compatibility with ancient Android
versions.
x86 and x86_64 crashes with libcrt, keep using libgcc for now.

The new module type bionic_mountpoint wasn't mutated by the sanitizer.
As a result, it has been taking non-sanitized symbol libraries even for
sanitized builds. Fixing the issue by making the module type to
implement the cc.Sanitizeable interface so that it can be mutated by the
sanitizer.

When free_track option is enabled and malloc debug detects error in
VerifyFreedPointer flow, if freed pointer's usable_size is more than
g_debug->config().fill_on_free_bytes(), the error log is not correct.
The max. bytes printed to error message should be the max bytes to
cmp, not usable size.

The log priorities and ids are in an NDK header, available to everyone.
Move CHECK into its own header for now. This would be better if it was
more like the <android-base/logging.h> CHECK family, but I don't have an
easy way to do that without lots of copy & paste, so punting for now.

All of the heapprofd code assumes that it's the only hook that
has been enabled. Enforce that by disallowing heapprofd from
enabling if malloc debug or malloc hooks have been enabled.
Test: Ran all unit tests (bionic/malloc hooks/malloc debug/perfetto).
Test: Enabled malloc debug ran perfetto integration tests and verified
Test: that an error message goes to the log.
