[sanitizer] Use mmap to zero-fill large shadow regions.
...
This is covered by existing ASan test.
This does not change anything for TSan by default (but provides a flag to
change the threshold size).

[sanitizer] Use system unwinder in signal handlers on Android.
...
Because of the way Bionic sets up signal stack frames, libc unwinder is unable
to step through it, resulting in broken SEGV stack traces.
Luckily, libcorkscrew.so on Android implements an unwinder that can start with
a signal context, thus sidestepping the issue.

[Sanitizer] Add Symbolizer::AddHooks() and use it in TSan and MSan.
...
Summary:
TSan and MSan need to know if interceptor was called by the
user code or by the symbolizer and use pre- and post-symbolization hooks
for that. Make Symbolizer class responsible for calling these hooks instead.
This would ensure the hooks are only called when necessary (during
in-process symbolization, they are not needed for out-of-process) and
save specific sanitizers from tracing all places in the code where symbolization
will be performed.

Overhaul the symbolizer interface.
...
This moves away from creating the symbolizer object and initializing the
external symbolizer as separate steps. Those steps now always take place
together.
Sanitizers with a legacy requirement to specify their own symbolizer path
should use InitSymbolizer to initialize the symbolizer with the desired
path, and GetSymbolizer to access the symbolizer. Sanitizers with no
such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for
initialization.
The symbolizer interface has been made thread-safe (as far as I can
tell) by protecting its member functions with mutexes.
Finally, the symbolizer interface no longer relies on weak externals, the
introduction of which was probably a mistake on my part.

[msan] Fix invalid origin copying.
...
Origin copying may destroy valid origin info. This is caused by
__msan_copy_origin widening the address range to the nearest 4-byte aligned
addresses both on the left and on the right. If the target buffer is
uninitialized and the source is fully initialized, this will result in
overriding valid origin of target buffer with stale (possibly 0) origin of the
source buffer.
With this change the widened origin is copied only if corresponding shadow
values are non zero.

[msan] Fix origin of deallocated memory.

MSan poisons deallocated memory but it used to give it an invalid origin value,
resulting in confusing reports. This change associates deallocation stack trace
with such memory.
Note that MSan does not have quarantine, and use-after-free detection is very
limited.

passed to the linker. By default, it contains interceptors and sanitizer
interface functions, but can be extended with tool-specific lists.
